Question

Which of the following correctly identifies the hormone and secretory cells that are responsible for low blood glucose?

a) Insulin secreted by alpha cell
b) Glucagon secreted by alpha cells
c) Insulin secreted by β cells
d) Glucagon secreted by β cells

Answer 1

Glucagon is secreted by β cells to increase blood glucose levels.

Step-by-step explanation:

The correct answer is d) Glucagon secreted by β cells.

The alpha cells in the pancreas secrete glucagon, while the beta cells secrete insulin. Glucagon is responsible for increasing blood glucose levels by promoting the breakdown of stored glycogen in the liver and releasing glucose into the bloodstream. On the other hand, insulin, which is secreted by the beta cells, helps lower blood glucose levels by facilitating the uptake of glucose by cells.
