Question

Insulin is an important hormone that allows the body to use glucose from food. After an individual eats a meal, glucose travels through the blood stream and reaches beta cells in the pancreas. The glucose causes the beta cells to release insulin. Insulin then travels through the blood stream and attaches to insulin receptors on other cells, which allows them to take in glucose and use it for energy.
What does this information best demonstrate?

A.
Only certain cells can use glucose to produce energy.
B.
Cells interact with other cells for regulation and homeostasis.
C.
A hormone is a protein that performs many functions in the body.
D.
Beta cells are not necessary for glucose to be utilized.
