An individual with chronic ethanol consumption exhibits significantly reduced gluconeogenesis. Which mechanism explains why this phenomenon occurs in the liver?

💡 Explanation

Ethanol metabolism in the liver increases the NADH/NAD+ ratio, which inhibits gluconeogenesis because this altered ratio reduces the availability of substrates needed for the process. Therefore, gluconeogenesis decreases, rather than increasing due to insulin sensitivity, glucagon, or glycogen synthesis.
