which of the following statements regarding insulin is not true?
a insulin reduces blood sugar levels.
b insulin stimulates the cells of the body to take in glucose from the bloodstream.
c insulin is secreted by the alpha cells of the pancreas.
d insulin is most active after you have eaten a meal.

Explanation:

• Insulin is secreted by beta cells of the pancreas, not alpha cells. Alpha cells secrete glucagon.
• Insulin reduces blood sugar levels by stimulating cells to take in glucose from the bloodstream. After a meal, blood sugar rises, and insulin is most active to lower it.

Answer:

C. Insulin is secreted by the alpha cells of the pancreas.
