Which of the following hormones inhibits gluconeogenesis, the formation of glucose from noncarbohydrate sources such as amino acids, glycerol, and fatty acids?

Insulin

Epinephrine

Cortisol

Glucagon

The correct answer will be option - Insulin.

Explanation:

Gluconeogenesis is the process of formation of sugar glucose from the non-carbohydrate sources during the less or no intake of carbohydrate from the diet.

Gluconeogenesis is controlled by a feedback mechanism which could be positive or negative. The positive feedback is controlled by the hormones like epinephrine, cortisol and glucagon but insulin shows negative feedback mechanism and inhibit the process.

Thus, option - Insulin is the correct answer.
