Question

which claim best describes how the body returns to homeostasis when blood sugar is too low?
a) the pancreas releases insulin to reduce glucose further.
b) the digestive system stores excess glucose in the stomach.
c) the pancreas releases glucagon, which causes the liver to release stored glucose.
d) cells increase cellular respiration to lower glucose needs.

Explanation:

When blood - sugar is low, the pancreas releases glucagon. Glucagon acts on the liver, stimulating it to release stored glucose (glycogenolysis) to raise blood - sugar levels and restore homeostasis. Insulin is released when blood - sugar is high, not low. The stomach does not store glucose. Increasing cellular respiration would increase glucose needs, not lower them.

Answer:

C. The pancreas releases glucagon, which causes the liver to release stored glucose.
