Which of the following is a peptide bond?

A.C-H bond
B.N-H bond
C.C-C bond
D.C-N bond

Answers

Answer 1

Answer:

The correct answer is - D.C-N bond

Explanation:

A chemical bond is formed between the carboxyl group of an amino acid to the amino group of the other amino acid and release a water molecule. It is a dehydration synthesis reaction.

So, the peptide bond normally formed by the reaction between amino acid from C1 of one amino acid molecule and N2 of the other amino acid molecule.

So the peptide bond that formed by this reaction is involve bonding of C-N bond.

The plant cell wall is made up of cellulose and the bacterial cell wall is made up of peptidoglycan.

What is a cell wall?

The cell wall is a protective covering found in plants and bacteria. When bacterial cell attacks the human system lysozymes are some kind of enzymes that degrades the human system.

Penicillin and lysozyme both affect the cell walls of bacteria. When bacteria divide, penicillin weakens their cell walls, causing them to burst and perish from osmotic pressure.

A little enzyme called lysozyme breaks down a bacterium's protective cell wall by attacking it.

Therefore, The plant cell wall is made up of cellulose, and the bacterial cell wall is made up of peptidoglycan.

analysis?

Answers

Answer: It would be the study of different plant varieties.

Explanation:

The one topic which study was the most crucial to his final analysis is the study of plant varieties. The correct option is B.

Who was Gregor Mendel?

Gregor Mendel discovered the fundamental laws of inheritance while working on pea plants. He deduced that genes are inherited in pairs and as distinct units, one from each parent.

Mendel studied the segregation of parental genes and how they manifested in offspring as dominant or recessive traits.

Mendel's First Law is particularly noteworthy because he made his observations and conclusions (1865) without having any prior knowledge of the relationships between genes, chromosomes, and DNA.

The law of segregation is the most important of these three laws because it has no exceptions and is universally accepted.

The study of plant varieties was the most important topic for his final analysis.

Thus, the correct option is B.

D. function in an acidic and basic environment

Answers

Answer:

D im pretty sure

Explanation:

Enzymes that work in the stomach must adjust to the unique environment by being able to function in an acidic environment.

Which enzyme would most likely function in the stomach?

One or more polypeptide chains of amino acids make up a big protein enzyme molecule. The unique protein folding patterns, which are crucial for enzyme specificity, are determined by the amino acid sequence.

Pepsin and rennin are the two primary enzymes found in gastric juice. While rennin coagulates the soluble milk protein, casein, into an insoluble curd, which is then attacked by pepsin, pepsin breaks down proteins into short polypeptide chains. Pepsin is produced by the chief cells of the stomach as pepsinogen, an inactive zymogen.

The plasma membrane found in both prokaryotic and eukaryotic cells is composed of a/an _______, which is semipermeable and controls the flow of molecules into and out of the cell.

Answers

Answer:

Phospholipid layer

Explanation:

The plasma or cell membrane is the outer covering of prokaryotic (bacteria) and eukaryotic (plants and animal) cells that provides support to the cytoplasm. The plasma membrane is made up of components like phospholipid layer, proteins, etc. However, the PHOSPHOLIPID LAYER component of the plasma membrane confers its SEMI-PERMEABILITY upon it.

The phospholipid layer consists of a hydrophilic i.e. water-loving region (phosphate head) and hydrophobic i.e. water-fearing region (fatty acid tails) that allows it to selectively control the flow of molecules into and out of the cell.

Explain in brief how the non-covalent weak interactions play a major role in biomolecular structure.​

Answers

Answer:

The type of intermolecular interactions of a set of molecules determines how they are grouped together. In the case of biological molecules, these types of non-covalent weak interactions have a great importance in the development of the vital phenomenon, since they allow the interaction of the different biomolecules with each other.

Explanation:

Non-covalent weak interactions are characterized by being long-range, that is, they act at a distance greater than 28 and by their weak binding energy (their binding energy is typically 10 to 100 times lower) so they can be created and break easily. These interactions are responsible for the final structure of macromolecules, for the specific binding between molecules, that is, for molecular recognition, for the self-organization processes of macromolecular and cellular structures, and for everything that involves movement and communication at the cellular and subcellular level. Its importance, therefore, is fundamental for all structural and functional aspects of living beings.

Describe the nonspecific antimicrobial effects of mucus, lysozyme, and acidic pH. For each of these substances, list where they are found in the body and how they function in fighting pathogens.

Answers

Answer: Non specific defence mechanism are the first lines of general defence that aids in preventing entry and minimising further passage of microbes and foreign materials into the body.

Explanation:

The non specific defence mechanisms protects us against any of enormous range of possible dangers using these methods:

--> defence at body surface

--> phagocytosis

--> natural antimicrobial substances

--> the inflammatory response and

--> immunological surveillance.

MUCUS is a slippery substance which covers the luminal surface of the Lungs. It provides defence at the body surfaces. Incase of any inhaled foreign material through the nose into the lungs, it's usually entrapped by the mucus. It is either coughed up or swallowed.

LYSOZYME: This is a protein with antibacterial properties present in granulocytes, tears and sweat. They are natural antimicrobial substances that destroys the cell walls of bacteria leading to its death.

ACIDIC Ph: The presence of acidic natural substances found in the stomach such as the gastric juice or hydrochloric acid, kills the majority of ingested microbes.

Answer:

B. 0 m

Explanation:

The graph given is a position - time graphical model of the motion of a body.

The y-axis denotes the position of the body and the x- axis is the time taken.

To solve this problem, since the velocity of the motion is constant and no acceleration, we trace up the point 6s on the x-axis and find the y-axis equivalent.

Completing the graph, the point lies on 0m. At 0m, the object would have traveled for 6s.

Why is the cell like a city?

Answers

Answer:

The cell is basically like a city because there are different parts of the cell that work together to keep a system running, therefore incredibly similar to a cell. There are parts to the cell such as the vacuole which acts as the storage for a cell, like the storeroom or bank in the city, and the lysosome which cleans up and recycles for the cell in away, acting as the recycle center or such for a city. Just like these few cell parts, there are many other parts which each have their respective "role" to functioning as a "city", and for those reasons a cell is like a city.

The cell is like a city because without it it’s nothing and the city is constantly moving and constantly there and so is the cell

Explanation:

An early step in the process of carbon fixation combines three molecules of CO2 with three molecules of RuBP to produce three 6-carbon molecules, which are immediately converted to six 3-carbon molecules. These six molecules are phosphorylated and reduced to produce glyceraldehyde 3-phosphate (G3P). What additional events occur to complete the Calvin cycle

Answers

Answer:

release of one G3P to make sugars and regeneration of RuBP

Explanation:

The Calvin cycle can be defined as a part of photosynthesis that utilizes the energy stored by light-dependent reactions to produce three-carbon sugars. The first carbohydrate produced by the Calvin cycle is a three-carbon sugar phosphate called glyceraldehyde-3-phosphate (G3P). Subsequently, G3P is used to produce other sugar molecules such as, for example, glucose. The Calvin cycle consists of three steps: 1-carboxylation (by using CO2 in a reaction catalyzed by Rubisco enzyme), 2-reduction of phosphoglycerate (ATP phosphorylation), and 3-regeneration of ribulose-bis-phosphate (RuBP) by using triose phosphates produced in the first two steps.
