Insulin-mediated uptake of glucose by cells

Question 7

If a person’s blood glucose concentration is measured at 180 mg/dL, which of the following is the most likely physiological response?

Accepted Answer

Increased insulin secretion from the pancreas

Question 8

Which of the following statements about the absorption of monosaccharides is correct?

Accepted Answer

Monosaccharides are absorbed directly into the bloodstream from the small intestine.

Question 9

A patient with diabetes mellitus is unable to regulate blood glucose effectively. Which hormone is most directly involved in this regulation?

Accepted Answer

Insulin

Question 10

Which of the following best describes the role of glycogen in the body?

Accepted Answer

It serves as a storage form of glucose in the liver and muscles.

Question 11

A person is fasting and their blood glucose levels begin to drop. Which process is most likely to occur to maintain homeostasis?

Accepted Answer

Glycogenolysis in the liver

Question 12

Which of the following is a correct sequence of events following the ingestion of carbohydrates?

Accepted Answer

Carbohydrates are broken down into monosaccharides, absorbed into the blood, and transported to cells for energy.

Question 13

Which of the following best explains the importance of maintaining blood glucose within a narrow range?

Accepted Answer

It ensures a constant supply of energy to the brain and other vital organs.

Question 14

Which of the following is a direct consequence of insulin deficiency?

Accepted Answer

Elevated blood glucose levels

Question 15

A patient is given a glucose tolerance test. After ingesting glucose, their blood glucose remains elevated for several hours. What does this most likely indicate?

Accepted Answer

Impaired insulin secretion or action

Question 16

Which of the following best describes the relationship between glucose and glycogen?

Accepted Answer

Glucose molecules are linked together to form glycogen for storage.
