Final answer:
Insulin is the hormone responsible for the body's ability to use glucose for energy, as it facilitates the uptake of glucose into cells. It regulates blood sugar levels and supports energy production by promoting glucose storage in the liver. Other hormones mentioned, like glucagon and cortisol, do not directly assist in glucose utilization.
Explanation:
Hormones and Glucose Utilization
In the human body, the hormone needed for the uptake and utilization of glucose for energy is insulin. Insulin is produced by the pancreas and plays a crucial role in regulating blood sugar levels. When you consume carbohydrates, they are broken down into glucose, which enters your bloodstream. Insulin is then released to facilitate the movement of glucose into the cells, where it can be used for energy.
Here are some key functions of insulin:
- Promotes cellular uptake of glucose, lowering blood sugar levels.
- Stimulates the liver to store glucose as glycogen for later use.
- Inhibits the production of glucose by the liver.
In contrast, hormones like glucagon serve to raise blood sugar levels by promoting the release of glucose from stores in the liver, while cortisol and serotonin are involved in different bodily functions and do not directly facilitate glucose utilization.
