Question

Which of the following influences the glucose levels in the human body?

• A. Insulin produced in the liver
• B. Glucagon produced in the kidneys
• C. Insulin produced in the kidneys
• D. Both insulin and glucagon
• E. Parathyroid hormone

Answer 1

The correct option is D Both insulin and glucagon

Antagonistic functions of insulin and glucagon hormones of pancreas maintain the homeostasis of blood glucose level. Insulin is secreted by islets of Langerhans of the pancreas and serves to lower the blood glucose level by stimulating the uptake of glucose by cells, specifically muscle cells, liver cells and adipose tissues cells. Liver and muscle cells store glucose as glycogen. Glucose serves as energy source for muscle contraction and in adipose tissues, it supplies glycerol for the formation of fat. Glucagon hormone from pancreas stimulates the liver to break down glycogen into glucose and breakdown of fat into glycerol and fatty acids in adipose tissues to serve as a substrate for glucose formation in liver cells. Thus, the correct answer is option D.
