Question

Insulin:

A. decreases plasma Ca+2

B. increases lipolysis

C. increases gluconeogenesis

D. increases protein synthesis

E. increases the plasma [glucose]

Answer 1

Answer

Option D) Increases protein synthesis

• Insulin is a peptide hormone released from endocrine portion (beta cells) of the pancreas.
• It is released when blood glucose levels rises above normal.
• It promotes glycogenesis to store excess glucose in cells of liver and muscle.
• Other effects of insulin includes :
  - Promoting transport of amino acids into the cell.
  - Increase rate of DNA transcription and mRNA translation.
  - Insulin prevents protein breakdown.
• All these collectively promotes protein synthesis.
