The  complete question is

Compared to the amount of genetic information contained in a normal human body cell, the amount contained in a normal human sperm cell is

A. the same

B.twice as much

c. one-half as much

D. one-fourth as much

One-half as much. Thus, option "C" is correct.

<h3>How, explain your answer?</h3>

The amount of genetic information contained in a normal human sperm cell (23 chromosomes) is one-half as much as the information contained in a normal human body cell (46 chromosomes).

Sperm cells are produced during meiosis, a specialized division process that reduces the number of chromosomes in half, generating haploid daughter cells.

Thus, option "C" is correct.

<u>Answer:</u>

Effects Include:

Activates secondary messengers such as cAMP which further activates number of hormones like

  • ADH: production of this hormone causes kidneys to retain more water inside body.
  • GHRH: release growth factors and stimulates growth of organism.
  • ACTH: produces fight or flight responses i.e rise in heart beat, rise in Blood pressure etc
  • TSH: Stimulate the synthesis of Thyroid hormone and enhances the metabolism of body. In rare cases causes Goiter without the deficiency of Iodine.
  • LH: Stimulate follicle maturation and formation of ovules in women.
  • Calcitonin: Decreases blood calcium level by deposition calcium in bones. This effect weakens the muscles.
  • Glucagon: Stimulates glycogen breakdown from liver and muscles and many more effects.

<u>Explanation:</u>

Background Knowledge:

GPCR (G Protien coupled receptors) are present inside plasma membrane in huge amount. As name suggest that these receptors are coupled with G proteins during their inactive state present inside of the cell. During their Inactive state these G proteins are bounded with GDP molecule.

Upon receiving signal molecules from outside of cell alters the shape of GPCR. These receptors also triggers change in G Protein, as a result of this GTP get attached with them. This protein further activates reaction cascades inside of the cell.

What happen if GTP cannot be hydrolyzed to GDP + Pi?

If GTP cannot hydrolyzed in to GDP + Pi than, it cannot be able to dissociate from G proteins. Cascade system doesn't stop and produces many effects on body.

Effects Include:

Activates secondary messengers such as cAMP which further activates number of hormones like

  • ADH: production of this hormone causes kidneys to retain more water inside body.
  • GHRH: release growth factors and stimulates growth of organism.
  • ACTH: produces fight or flight responses i.e rise in heart beat, rise in Blood pressure etc
  • TSH: Stimulate the synthesis of Thyroid hormone and enhances the metabolism of body. In rare cases causes Goiter without the deficiency of Iodine.
  • LH: Stimulate follicle maturation and formation of ovules in women.

How would an inhibitor of cAMP phosphodiesterase affect glucose mobilization in muscle? It would increase cAMP levels, which wou
dedylja [7]

Answer:It would maintain high cAMP levels and elevate glucose mobilization.

Explanation:

Gas stimulates adenylate cyclase, leading to the generation

of cAMP. This signal then leads to glucose mobilization. If cAMP phosphodiesterase were inhibited, then

cAMP levels would remain high even after the termination of the

epinephrine signal, and glucose mobilization would continue
