1)Explain how gluconeogenesis ang glucogenolysis are regulated to maintain blood glucose levels during fasting
Step by step
Solved in 2 steps
- In the absence of food consumption, the rate of gluconeogenesis (GNG) tends to increase. Explain why this occurs and describe the range of substrates for GNG as fasting continues beyond 18 hours. asapyou follow a carbohydrate-free diet, certain metabolic problems occur. Describe glucogenesis and the problems that may arise from this prolonged glucogenesis state.Glycogen synthesis and breakdown are regulated primarily at the hormonal level.
