A stressful stimulus triggers both rapid neural responses and slower hormonal responses. The nervous system immediately increases heart rate, while endocrine signaling sustains elevated metabolism over time. Which statement BEST explains the difference between these two systems?

Intestinal epithelial cells absorb glucose from the lumen even when intracellular glucose concentration is higher. This process relies on a sodium gradient established by the Na⁺-K⁺ pump. Which mechanism BEST explains glucose uptake in this scenario?

During a stressful situation, the sympathetic nervous system is activated. Heart rate increases, pupils dilate, and glucose is released into the bloodstream. Which hormone MOST directly supports this metabolic response?
