Question: 1 / 400

Which hormone is released upon consuming 100 grams of carbohydrates?

Testosterone

Insulin

When 100 grams of carbohydrates are consumed, insulin is released as a natural response to rising blood glucose levels. Insulin is a hormone produced by the pancreas that plays a crucial role in glucose metabolism. When carbohydrates are digested, they are broken down into glucose, which enters the bloodstream, leading to an increase in blood glucose levels.

In response to this glucose surge, the pancreas secretes insulin, which facilitates the uptake of glucose by cells for energy or storage in the form of glycogen. This process helps to lower blood glucose levels back to a normal range, making insulin essential for maintaining metabolic homeostasis after carbohydrate intake.

By understanding the role of insulin in carbohydrate metabolism, one can appreciate how the body regulates energy supply and maintains optimal physiological function following a meal rich in carbohydrates.
