← Human Body & HealthWhy does chronic alcohol consumption increase the risk of hypoglycemia even when glycogen stores are present?
A)Increased insulin receptor sensitivity occurs
B)Ketogenesis inhibits liver gluconeogenesis
C)Ethanol metabolism inhibits gluconeogenesis✓
D)Glycogenolysis becomes severely impaired
💡 Explanation
Chronic alcohol consumption increases the risk of hypoglycemia because ethanol metabolism in the liver increases the NADH/NAD+ ratio, inhibiting gluconeogenesis, a process critical for glucose production. Therefore, the liver can't synthesize glucose, rather than increased receptor sensitivity compensating or glycogenolysis being severely impaired.
