Answer:

Gills

Along with insulin, amylin is a hormone that a diabetic pancreas fails to produce. It is comprised of a long chain of amino acid
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.

Select all that apply. Which of the following are not properties of enzymes
AlladinOne [14]
Enzymes are proteins that are biological catalysts

They reduce the activation energy required for a reaction to occur and thus speed up a reaction

Temperature, above a certain point (optimum temperature) causes them to break down and they are gradually destroyed (denaturing)

They work best at a particular pH (optimum pH) and are once again destroyed by low or high pH's

They have a specific shape, with one particular part, known as the active site, that is specific to the substrate they speed the reaction of. These means they are specific to one type of reaction.

They aren't used in the reaction so they're re-usable.

If it isn't one of these then it is not one of the properties of enzymes
