Final answer:
Regulating blood glucose levels is important when we are starving because the brain relies on glucose as its main source of energy.
Step-by-step explanation:
Regulating blood glucose levels is important when we are starving because the brain relies on glucose as its main source of energy. When blood glucose levels drop too low, it can lead to hypoglycemia, which can cause symptoms like weakness, tremors, and even coma and death. In starvation, the body uses ketones and alternative fuels to provide energy for the brain, but it is still important to maintain blood glucose levels within a normal range to ensure proper cellular function.
