Question

Select each statement that correctly describes a similarity between glucagon and insulin signaling pathways.

a. Most of the time, both signaling pathways have the same effect on metabolic enzyme activity.
b. In both pathways, hormone binding induces a conformational change in the membrane receptor.
c. Stimulating the signaling pathway for both hormones eventually activates kinases.
d. For both pathways, the concentration of second messengers increase in the cell as a result of hormone-receptor interactions.

Answer 1

Answer:

"B and D" are the correct statement.

Explanation:

The endocrine and internal secretion pathways don't have identical impact on the metabolic protein activity. While endocrine constrains the polyose synthase protein, internal secretion up regulates it.

The second traveler just in case of endocrine sign is cAMP, whereas in internal secretion sign pathway it's PIK3. The attentions of each the additional envois rise within the cell as a results of their individual receptor inspiration.

Binding of each the endocrine and internal secretion to their individual receptors encourages a conformation modification within the receptors as a results of that the receptors are stimulated.

Glucagon is answerable for triggering polyose synthase kinase-3 (GSK-3). Associate stimulated GSK-3 inhibits polyose synthase specified glycogen equal within the cell declines and aldohexose levels will increase. On the opposite hand, internal secretion is answerable for constraining GSK-3. Therefore, the protein polyose synthase residues in an energetic type and glycogen synthesis is endorsed.

Answer 2

A hormone that can treat low glucose levels is called glucagon. It stimulates the glycogen stored in the liver to split into glucose when needed.

Insulin is also a hormone that is involved the maintaining blood sugar level and metabolism.

The correct answer is:

• Option B. In both pathways, hormone binding induces a conformational change in the membrane receptor.

• Option D. For both pathways, the concentration of second messengers increase in the cell as a result of hormone-receptor interactions.

This can be explained as:

• The inner secretion and endocrine pathways do not have the same effect on metabolic protein action.

• Endocrine stifles the polyose synthase protein, while internal discharge up-regulates it.

• The coupling of each internal and endocrine secretion to their receptors stimulates a structure alteration within the receptors as a consequence that the receptors are incited.

• Glucagon is responsible for triggering polyose synthase kinase-3 (GSK-3). Cohort excited GSK-3 represses polyose synthase specified glycogen level within the cell slumps and aldohexose levels will raise.

• On the contrary, internal secretion is accountable for restraining GSK-3.

Therefore, the protein polyose synthase deposits in an energetic kind and glycogen synthesis is supported.
