Gluconeogenesis in the liver and the absorption of carbohydrates in the liver provide glucose for ATP production by neurons. The nervous system, including the brain, requires a constant supply of glucose for energy production. The digestive system helps ensure that glucose is available by breaking down carbohydrates in the diet and converting non-carbohydrate sources into glucose in the liver. This glucose is then transported to the brain and other neurons for energy production.
