Question

Fully explain how multiple hormones are used to control the rate at which glucose is consumed during cellular respiration.

Answer 1

Insulin and glucagon are two hormones secreted by the pancreas involved in glucose metabolism.

insulin is secreted by the beta cells of the islets of Langerhans and contributes to lowering blood sugar levels. In this case, insulin causes the body's cells to absorb blood glucose in order to reduce it.

while glucagon is secreted by the alpha cells of the islets of Langerhans and contributes to the increase in blood glucose concentration. In this case, glucagon stimulates the liver to release glucose into the bloodstream.

since insulin is secreted when there is a lot of glucose in the blood and glucagon when there is little sugar in the blood, these two mechanisms are opposite and regulate each other, to achieve homeostasis or balance in the organism.
