1. Which of the following is NOT an action of insulin? A) antilipolysis B) synthesis of glycogen in skeletal muscle C) synthesis of fatty acids in skeletal muscle D) synthesis of glycogen in the liver E) synthesis of proteins in most cells

The correct answer is C) synthesis of fatty acids in skeletal muscle.<br /><br />Insulin is a hormone that plays a crucial role in regulating glucose metabolism and maintaining blood glucose levels. It promotes the synthesis of glycogen in skeletal muscle and the liver, which helps to store glucose for. Insulin also promotes protein synthesis in most cells, which is essential for growth and repair. Additionally, insulin inhibits lipolysis, which is the breakdown of fat into fatty acids and glycerol. However, insulin does not promote the synthesis of fatty acids in skeletal muscle. Instead, it inhibits the synthesis of fatty acids in adipose tissue, which helps to reduce the storage of fat.
