diamong [38]

Options:

A prostaglandin

B protein hormone

C. peptide hormone

D. steroid hormone

Answer:

Amylin is peptidal harmone. Thus, the correct option is C.

<h3>What is hormone?</h3>

Hormones are the chemical messengers of the body. They make their way through your bloodstream to tissues and organs. They have a long-term effect on a variety of processes, including growth and development.

Amylin is a peptide hormone produced in tandem with insulin by the pancreatic -cell and is hence lacking in diabetics. It works as a satiety agent by inhibiting glucagon secretion and delaying stomach emptying. As a result, amylin replacement could potentially improve glycemic control in some diabetics.

Amylin is a 37-amino-acid peptide hormone released by pancreatic beta-cells in response to a food stimulation together with insulin. It is inadequate in Type 1 diabetes patients and increased in Type 2 diabetes patients in the early stages, a disease marked by hyperinsulinemia.

What statement about the mechanism of hunger and satiety is true?
disa [49]

Answer:

The correct answer is: The ventromedial hypothalamus plays a role in satiety.​

Explanation:

The hypothalamus is a part of the brain that controls many important bodily functions and connects both the nervous system with the endocrine system. The hypothalamus consists of several nuclei that have diverse functions and are located in 3 different regions.

The nucleus that plays a role in satiety is the ventromedial nucleus, terminating hunger and giving a sensation of fullness. It also plays a significant role in thermoregulation, among other things.

Neuropeptide Y, on the other hand, is a peptide that is released to make us feel hungry and encourage us to intake food (primarily carbohydrates).

Cholecystokinin is a hormone released by the small intestines after we had a meal, and its function is to improve digestion and make us feel full.

Fat cells DO release leptin, but the function of this hormone is to produce satiety, by stimulating anorexigenic (meaning they take hunger away) hormones and inhibiting orexigenic ones, like Neuropeptide Y.
