Before a meal, when blood glucose drops 10% below its resting value, which glucose transporter is working furthest from its Vmax?

1. GLUT3, because it has a very low Kt, which protects glucose supply to the brain.
2. GLUT4, because its Kt is most similar to normal blood glucose levels.
3. GLUT2, because it has a very high Kt, which helps regulate insulin production and removal of glucose from the blood.
4. GLUT1, because it has a moderately low Kt, which provides a constant flow of glucose into most cells of the body to maintain their basal cellular functions.

Elevated levels of adrenaline stimulate which of the following?

1. Glycogen synthesis by the liver
2. Gluconeogenesis in the liver
3. Insulin secretion by the pancreas
4. Glycogen synthesis by muscles

How does insulin lower blood glucose levels?

1. Stimulates the conversion of fats to glucose
2. Inhibits the breakdown of glycogen to glucose
3. Inhibits glucose uptake by muscle and adipose tissue
4. Stimulates the conversion of amino acids to glucose

Glucagon signalling would result in increased overall levels of activity of which of the following enzymes?

1. Debranching enzyme
2. Pyruvate decarboxylase
3. L-Phosphofructokinase-1
4. Glycogen synthase
