(4pts) Drugs, medicines, and poisons often work by acting on endogenous proteins. They do this by looking similar to a signal molecule and binding to the endogenous protein. Look up these four examples to fill in this chart. Drug, medicine, or poison Looks similar to this endogenous molecule: Binds to this endogenous protein/receptor: Muscarine Acetylcholine muscarinic receptors Prozac Serotonin serotonin transporter protein Ketamine NMDA NMDA receptor Tamoxifen estrogen estrogen receptor

Answers

Answer 1

Answer:

Drug, medicine, or poison: Muscarine; Looks similar to this endogenous molecule: Acetylcholine; Binds to this endogenous protein/receptor: muscarinic receptors

Drug, medicine, or poison: Tamoxifen; Looks similar to this endogenous molecule: estrogen; Binds to this endogenous protein/receptor: estrogen receptor

Drug, medicine, or poison: Prozac; Looks similar to this endogenous molecule: Serotonin; Binds to this endogenous protein/receptor: serotonin transporter protein

Drug, medicine, or poison: Ketamine; Looks similar to this endogenous molecule: NMDA; Binds to this endogenous protein/receptor: NMDA receptor

Explanation:

Muscarine is a poisonous natural product found in certain mushrooms. It is similar to acetylcholine and competes with acetylcholine at its receptor binding sites.Signs of muscarine poisoning include salivation, lacrimation, vomiting, diarrhea, abdominal pain, bradycardia, etc.

Tamoxifen is a selective estrogen receptor modulator. It is similar to estrogen and acts by inhibiting the effects of estrogen in the breast tissue. It is used to prevent and treat breast cancer in men and women.

Prozac is an antidepressant which belongs to th class known as selective serotonin reuptake inhibitors. It looks similar to serotonin and inhibits its action by competing with serotonin for its binding site. It is used for the treatment of depression disorders.

Ketamine is an NMDA (N-Methyl-D-aspartate) receptor antagonist. NMDA receptor antagonists are a class of drugs that work by inhibiting the action of the NMDA receptor. They are commonly used as anesthetics for animals and humans to induce a state of anesthesia known as dissociative anesthesia.

this is you're answer please give me thanks

Answer:

   In cells, oxygen is needed for aerobic respiration, which allows for the extraction of energy from ingested foods. Thus supplemental oxygen at home and in hospitals is vital for those with breathing disorders such as emphysema.

   Compressed oxygen tanks are used by mountaineers at high elevations to counteract the decreased O2 pressure at these altitudes.

   Supplemental oxygen is needed for surgical patients intentionally rendered paralyzed for medical procedures, in which "heart-lung machines" keep their vital functions going.

   Oxygen can be used as a sterilizing agent to kill certain anaerobic bacteria that are killed by sufficient exposure to the gas.

Industrial Uses of Oxygen:

   Oxygen is needed for the reaction that converts carbon to carbon dioxide gas in steel working, which takes place under high temperatures in a blast furnace. The carbon dioxide produced allows for the reduction of iron oxides into more pure iron compounds.

   Oxygen is used in other applications involving metal and requiring high temperatures, such as welding torches.

Aerospace Uses of Oxygen:

   In liquid form, oxygen is used widely as an oxidizing agent for use in missiles and rockets, where it reacts with liquid hydrogen to produce the terrific thrust needed for take-off. Astronaut spacesuits include a nearly pure form of oxygen.

   Oxygen is used to degrade hydrocarbon compounds, which are broken apart by heating them. This is used to create combustion that usually liberates water and carbon dioxide, but can also produce the hydrocarbons acetylene, propylene and ethylene.

   Oxygen is used in sewage-treatment and water-purification plants. It is forced through water to increase the production of bacteria that metabolize waste products in the water.

   Oxygen gas (O2) is needed to produce energy in things not linked to an electrical supply of their own, such as generators and vehicles (e.g., ships, airplanes and cars).

What other cofactors or cosubstrates does the pyruvate dehydrogenase complex require to function?

Answers

Answer:

Pyruvate dehydrogenase (PDH) is a very high molecular weight mitochondrial multienzyme complex.It includes three types of enzymes that need the participation of five coenzymes to develop their activity, three of them catalytic cofactors (TPP, lipoamide, FAD) and two stoichiometric (NAD and CoA). Two enzymes involved in regulating its activity are also part of the enzyme complex.

Explanation:

PDH is a multienzyme complex formed by multiple copies of three catalytic proteins (E1, E2 and E3) and other structural and regulatory (phosphatase, kinase). It requires, in turn, different coenzymes (thiamine, lipoic acid) for its proper functioning. Given its enormous importance at a key point in energy production, it is highly regulated. E1 depends on thiamine pyrophosphate and catalyzes 2 stages: 1) decarboxylation of pyruvate, forming a hydroxyethyl-thiamine-diphosphate intermediate; 2) reductive acetylation of the lipoyl group, covalently linked (amide) to E2. E2 catalyzes the transfer of the acetyl group to CoA (3). E3 regenerates the oxidized lipoyl, transferring its electrons first to FAD and then to NAD.

The platypus bill has a multitude of receptors on it. Initially, researchers thought that the receptors were all mechanoreceptors (i.e. for sensing textures, shapes) because platypus can not smell or detect odors underwater. The scientific community was shocked (pun intended) when it was reported that some of the receptors were actually electroreceptors. Design an experiment to determine if platypus prefer to hunt for prey through mechanoreception or electroreception

Answers

Answer:

Experiment: to put insect preys with different textures (but of the same group, for example, moths) into two conditions: 1-pure water and 2-ion-rich water solution. For this experiment, it is important to highlight that the platypus is a semiaquatic mammal that eats insects that fall into the water. Pure water is a poor conductor of electricity, while water containing charged ions (and also impurities) is a good conductor of electricity. In consequence, if the platypus prefers to hunt through electroreception, it is expected that the ability for hunting will be better in an ion-rich water solution than in pure water. Second, if the platypus prefers to hunt through mechanoreception, it is expected that the ability for hunting will vary depending on the type of texture that exhibits insect preys (in this case, moths).  

Explanation:  

Mechanoreception can be defined as the ability to detect and respond to a stimulus by using sensory cells (neurons) that respond to mechanical pressure and/or distortion, while electroreception is the ability to respond to electrical stimuli, thereby detecting weak electric fields in water. In the experiment above described it is possible to determine the hunting preferences under differential electroreception/mechanoreception conditions. Statistical scores such as p-value can be used to determine the outcome of the experiment.

Why is the hydrolysis of water required for photosynthesis?

Answers

Hydrolysis is a chemical process in which a water molecule is inserted.

In light-based reaction, which occurs in the thylakoid layer, chlorophyll absorbs energy from the sun and converts it into chemical energy through water. Light-dependent reactions release oxygen to water hydrolysis as a by-product.

Hope it helps!

Water is one of the most important components of photosynthesis. The hydrolysis of water is required to provide the Electrons and protons( Hydrogen ions) in photosynthesis.

Light Reaction photosynthesis:

It is the phase in which plant cells produce NADPH and ATP via the energy of the electron transport chain.

In this phase,

The water hydrolyzes to produce, electrons and Hydrogen Ion. Electrons move in from protein to protein and release their energy.This energy is used to pump the more hydrogen ion into the thalakoid lumen. The final electron is used to reduce the NADP molecule.

Therefore, the hydrolysis of water is required to provide the Electrons and protons( Hydrogen ions) in photosynthesis.

Meerkats live together in groups to help raise and protect their offspring. Meerkat pups are most vulnerable when they are away from their burrow foraging for food. Adult meerkats exhibit sentinel behavior, standing upright and making alarm calls to warn other members in the group that predators are nearby. In a study of meerkat behaviors, scientists observed meerkat foraging groups and recorded the presence or absence of pups along with the frequency of adult sentinel behavior. The scientists determined that sentinel behavior increased when pups were present in the foraging group. Which of the following correctly identifies the dependent and independent variables in the described study? A. The frequency of sentinel behavior is the independent variable, and the presence of pups is the dependent variable. B. The presence of pups is the independent variable, and the frequency of sentinel behavior is the dependent variable. C. The number of predators is the independent variable, and the presence of pups is the dependent variable. D. The distance from the burrow is the independent variable, and the number of predators is the dependent variable.

Answers

Answer:

The correct answer is - option B. The presence of pups is the independent variable, and the frequency of sentinel behavior is the dependent variable.

Explanation:

The independent variable in a study or experiment is a variable that is subject to change or manipulated to see the effect on the result of the study by influencing the dependent variable. In this study, the independent variable that is manipulated is the presence of the pups to see what is led to the behavior of meerkats.

The dependent variable is a variable that is influenced in a study by the independent variable and led to the result of the study as the frequency of sentinel behavior is influenced by the presence of the pups so the dependent variable here is the frequency of sentinel behavior.

Explanation:

The decomposers are the small microorganisms which can be found in the soil habitat. These organisms obtain energy by break down of organic matter generated after the death of plants, animals and their residual matter. Through the process of decomposition the decomposers release nutrients such as nitrogen and carbon back to the environment. These nutrients are absorbed by the plants through soil. This way the nutrients are recycled in an ecosystem by decomposers.
