Answer 1

1).

D) 2 9.1

It is estimated that about 29.1 million Americans have diabetes (more than 29 million as per 2015 estimates)

2).

C) unlock cells to allow glucose to enter and be used as energy

Insulin is a pancreatic endocrine hormone that convert glucose into glycogen and also increase the cellular uptake of glucose. The surface insulin receptors allow the cellular uptake of glucose and favor energy production from the glucose.

3).

B) occurs when normal cells are attacked by the immune system.

Type I diabetes mellitus (Type I DM) is an autoimmune disorder, which occurs due to the destruction of pancreatic islet cells (beta type), the insulin secretion decreases. So, patients suffering from “Type I DM,” have to take insulin from the external source in the form of injections. It is insulin-dependent DM.
