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

Answer 1

D cells interact with other cells for regulation and homeostasis

Answer 2

Answer:

Cells interact with other cells for regulation and homeostasis.

Explanation:

• Insulin is an anabolic peptide hormone that is secreted by the b cells of the pancreas. It works by binding to a receptor on the membrane of target cells, the most important of which are the liver (where it encourages the storage of glucose as glycogen and reduces glucose output), skeletal muscle, and fat (where it stimulates glucose transport by translocating GLUT4), as well as b cells, brain cells, and actually most cells, where it has pleiotropic
• Numerous physiological processes are driven by cell-cell interactions, which also support coordinated functioning in multicellular animals.
• Cell signaling is a universal mechanism used by all cells to recognize and react to environmental signals. This process not only encourages the appropriate operation of individual cells but also permits interaction and coordination between cell populations, including the cells that make up the tissue-based structured communities.
• The homeostasis, or equilibrium, that exists within a tissue is maintained by these signaling pathways.
