Multiple choice

What is the primary role of insulin in the regulation of glucose metabolism?

  1. Stimulates glucose uptake by cells

  2. Inhibits glucose production by the liver

  3. Promotes the storage of glucose as glycogen

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Insulin acts as a key regulator of glucose metabolism by promoting glucose uptake by cells, inhibiting glucose production by the liver, and facilitating the storage of glucose as glycogen.

Multiple choice

What is the main function of glycogen in the liver?

  1. Storage of glucose for energy production

  2. Regulation of blood glucose levels

  3. Gluconeogenesis

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Glycogen is a complex carbohydrate stored in the liver and muscles. Its primary function is to serve as a storage form of glucose for energy production. Additionally, glycogen plays a crucial role in regulating blood glucose levels by releasing glucose into the bloodstream when needed.

Multiple choice

What is the main function of the sodium-potassium pump in cellular transport?

  1. Maintenance of the cell membrane potential

  2. Active transport of sodium and potassium ions

  3. Regulation of cell volume

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The sodium-potassium pump, also known as the Na+/K+-ATPase, is a membrane protein that plays a crucial role in cellular transport. It actively transports sodium and potassium ions across the cell membrane, maintaining the cell membrane potential, regulating cell volume, and facilitating the transport of other molecules.

Multiple choice
