How does water form during cellular respiration?

Answers

Answer:

The electron transport chain is the third and final step of cellular respiration. Toward the end of the electron transport chain, the hydrogen from the coenzymes meets the oxygen that the cell has consumed and reacts with it to form water. In this way, water is created as a byproduct of the metabolism reaction.

Describe the importance of receptors in cellular communication

Answers

Answer:

Cells have proteins called receptors that bind to signaling molecules and initiate a physiological response. Different receptors are specific for different molecules. ... This is important because most signaling molecules are either too big or too charged to cross a cell's plasma membrane

Explanation:

hope this helps you have a good day

Receptors are transmembrane proteins, that bind to signaling molecules outside the cell and later transmit the signal through a sequence of molecular switches to internal signaling pathways.

What are types of cellular receptors?

Membrane receptors fall into three major classes namely G-protein-coupled receptors, ion channel receptors, and enzyme-linked receptors.

Not all receptors exist on the exterior of the cell. Some exist deep inside the cell, or even in the nucleus. These receptors typically bind to molecules which can pass through the plasma membrane, such as gases like nitrous oxide and steroid hormones like estrogen.

PLEASE ANSWER FAST! In the cells of an organism, the synthesis of biological molecules involves chemical reactions that have a positive change in free energy. Which of the following best explains the impact of this change in free energy?


A. It allows spontaneous reactions to occur.

B. It causes a decrease in entropy.

C. It causes the cell to give off heat.

D. It moves the cell toward equilibrium.

Answers

it seem to me B will be the answer just base off the question but let me reread that before anything

When a molecule is biologically molecule synthesized, there will be a monomer unit converted into the polymer, so there is a change in molecule randomness so entropy is decreased, hence option b is correct.

How biological molecules is synthesized?

When a biological molecule is synthesized the monomeric unit is converted into the polymeric unit and there will be a synthesis of bonds.

In a biological system, the system moves towards the spontaneous system, and the change in entropy should be increased. The biological system works only when it is a thermodynamically active system.

All the chemical reactions are held to move towards the equilibrium state when a biological molecule is synthesized change in the entropy of the system is decreased but a change in the entropy of the surroundings increases.

Therefore during the synthesis of biological molecules, entropy is decreased, hence option b is correct.

How does a cold day affect enzyme activity during photosynthesis?

Answers

Answer:

At low temperatures, between 32 and 50 degrees Fahrenheit – 0 and 10 degrees Celsius – the enzymes that carry outphotosynthesis do not work efficiently, and this decreases the photosynthetic rate. This leads to a decrease in glucose production and will result in stunted growth.

How is a species’ population dynamics affected by the presence of another species with the same niche?

Answers

Answer:

If two species occupied the same niche, they would be competing for the exact same resources. The competitive exclusion principle states that one of the species would drive the other to extinction.

Two species would be in direct competition for the same resources if they both occupied the same niche. According to the competitive exclusion principle, one of the species would inevitably wipe out the other.

What is niche?

It defines how an organism or population responds to the distribution of resources and competitors.

(for instance, by growing when resources are abundant and when predators, parasites, and pathogens are scarce) and how it then modifies those same factors.

According to the competitive exclusion principle, often known as Gauss's law, two species that are vying for the same resource in the same habitat but occupy distinct niches cannot coexist at constant population values.

Two species can dwell peacefully in ecological niches without facing any rivalry. It encourages diversity and keeps the food chain in balance.

Therefore, population dynamics affected by the presence of another species with the same niche.

Which process does not add carbon to the atmosphere?

Answers

Answer:

photosynthesis

Explanation:

Plants and photosynthetic algae and bacteria use energy from sunlight to combine carbon dioxide (C02) from the atmosphere with water (H2O) to form carbohydrates. Oxygen (O2) is a byproduct that is released into the atmosphere.

Photosynthesis does not add carbon to atmosphere.

What is Photosynthesis?

The process by which light energy is transformed into chemical energy in the form of sugars is known as photosynthesis. Using light energy, glucose (or other sugars) are created from carbon dioxide and water, with oxygen being released as a byproduct.

The glucose molecules act as the fuel for the cells; their chemical energy can be obtained through procedures like cellular respiration and fermentation, which result in the production of adenosine triphosphate (ATP), a small energy-carrying molecule, to meet the immediate energy requirements of the cell.

It is possible for organic molecules to integrate inorganic carbon from carbon dioxide; this process is known as carbon fixation, and the carbon in organic molecules is also known as photosynthesis.

Therefore, Photosynthesis does not add carbon to atmosphere.
