d) epinephrine

72. Which of the following is not considered a gluconeogenic hormone?

a) cortisol

b) insulin

c) glucagon

d) epinephrine

Answer 1

Q95) c. Myonucleus.

The process of protein synthesis always begins in the nucleus by synthesis of mRNA.

Q90) a. Carnitine transports fatty acids across the mitochondrial membrane.

Q71) insulin.

Insulin is used to push glucose molecules inside the muscle cells and adipocytes to normalise the blood glucose. The receptors activated are GLUT4. When exercising, GLUT4 receptors do not require insulin for its activation.

Q72) insulin.

Gluconeogenic hormone are those hormones which raise blood glucose level. Insulins lowers blood glucose.
