How might a change of one amino acid at a site, distant from the active site of an enzyme, alter the substrate specificity of an enzyme?

Answers

Answer 1

Answer:

Answer:

An enzyme is a protein. Any change in the primary structure of a protein (the primary structure is the aminoacid sequence) can induce a change in the secondary, as well as tertiary structure (tridimensional conformation). This change in the shape of the enzyme can affect its activity, since it can change the active site consequently to this conformational change.

Proteases and acrosin are enzymes. How do they function in reproduction? A Their function is unknown. B They direct the sperm to the egg through chemical messengers. C They neutralize the mucous secretions of the uterine mucosa. D They act to break down the protective barriers around the egg, allowing the sperm

Answers

Answer: D. They act to break down the protective barriers around the egg, allowing the sperm.

Explanation:

Acrosin and other protease enzymes functions by the catalyzing the proteolysis, that is the breakdown of proteins into small polypeptides by cleaving the peptide bonds within the proteins by the process of hydrolysis.

The acrosine and other protease enzymes are released by the acrosome cap of the spermatozoa. This process facilitates the enzymatic digestion of zona pellucida layer of the egg. This helps in the penetration of egg by the sperm.

Growth of chest hair, deepening of the voice, and muscle growth are secondary sex characteristics. Which most likely affects the development of these traits? testes ovaries prostate gland vulva

Answers

Answer: testes

Explanation:

The testes are the male gametes which are present inside the pouch called as scrotum. The testes perform two functions that is they produce sperms and male sex hormone testosterone. The hormone testosterone is secreted by the cells of the seminiferous tubules also called as Leydig cells. The testosterone in males start producing during puberty. It is responsible for the development of secondary sexual characteristics in males like growth of facial, axial, chest and pubic hair, deepening of voice and growth of the muscles.

The testes is the most likely to affect the development of these.
