Final answer:
Insulin decreases gluconeogenesis, enhances glucose transport into cells, and stimulates glycogen synthesis, which are all actions that lower blood glucose levels.
Step-by-step explanation:
From the list provided, the metabolic effects of insulin include:
- b. decreases gluconeogenesis: Insulin inhibits the enzymes involved in the production of glucose in the cells, thus reducing the generation of glucose from non-carbohydrate sources.
- e. enhances glucose transport: Insulin triggers body cells to take up glucose from the blood by increasing the translocation of Glut-4 transporter to the plasma membrane.
- f. stimulates glycogen synthesis: Insulin promotes the liver to convert excess glucose into glycogen for storage, enhancing glycogenesis.
It's important to note that insulin lowers blood glucose levels rather than increasing them. This is achieved through several mechanisms including enhancing glycolysis, the metabolism of glucose for the generation of ATP, as well as promoting triglyceride and protein synthesis.
