What is the function of adiponectin in glucose metabolism?

• A. It decreases insulin sensitivity
• B. It enhances insulin sensitivity and fatty acid oxidation
• C. It promotes glucose reabsorption in kidneys
• D. It inhibits fatty acid oxidation

Answer: (B)

Adiponectin plays a crucial role in glucose metabolism by enhancing insulin sensitivity and promoting fatty acid oxidation. It is a hormone secreted by adipose tissue and serves as a critical factor in regulating glucose levels and fat metabolism in the body. When adiponectin levels are elevated, insulin sensitivity in peripheral tissues, particularly in muscle and liver, is improved. This increased sensitivity means that the body can utilize insulin more effectively to lower blood glucose levels. Furthermore, adiponectin encourages the oxidation of fatty acids, which helps to reduce the concentration of fatty acids in the bloodstream. This dual action helps to maintain energy balance and normal glucose homeostasis. Consequently, the enhancement of insulin sensitivity and fatty acid oxidation contributes to better overall metabolic health and reduces the risk of conditions such as type 2 diabetes and cardiovascular diseases. The interactions of adiponectin with various signaling pathways underscore its importance in managing glucose and lipid metabolism effectively.
