What occurs in response to high levels of glucose in the body?

• A. Release of glucagon
• B. Increased cellular respiration
• C. Inhibition of insulin secretion
• D. Stimulated release of insulin

Answer: (D)

When glucose levels in the body rise, such as after eating a meal, the pancreas responds by stimulating the release of insulin. Insulin is a hormone that plays a crucial role in regulating glucose metabolism. It facilitates the uptake of glucose by cells, particularly in muscle and fat tissues, allowing them to utilize glucose for energy or store it as glycogen for later use. This action helps lower elevated blood glucose levels to maintain homeostasis.

In addition to promoting glucose uptake, insulin also inhibits glucose production in the liver and stimulates the synthesis of fatty acids and proteins, further supporting energy storage and metabolism. The overall effect of insulin release in response to high glucose levels is critical for managing energy resources in the body and ensuring that cells receive the glucose they need for energy production.
