Final answer:
Insulin promotes adipogenesis by facilitating the conversion of glucose to fat in adipocytes and inhibiting the breakdown of fat, making it an anabolic hormone that enhances fat storage.
Step-by-step explanation:
The correct answer is B. Insulin promotes adipogenesis. Insulin plays a crucial role in the body's metabolic processes. It regulates blood glucose levels by stimulating the uptake and storage of glucose in the form of glycogen in liver and muscle tissues. Additionally, insulin facilitates the conversion of glucose to fat in adipocytes, which is the process known as adipogenesis. Insulin triggers the differentiation of pre-adipocytes into adipocytes and stimulates lipogenesis, the process of converting glucose into triglycerides for storage in fat cells. Furthermore, insulin inhibits the breakdown of fat in adipose tissue, thereby promoting an increase in fat storage. The actions of insulin on adipose tissue are part of the reason why it is considered an anabolic hormone, as it promotes the synthesis and storage of energy substrates.
