This document contains a test on physiology concepts from Alex School of Medicine. It includes 24 multiple choice questions covering topics like ATP production, basal metabolic rate, specific dynamic action of food, respiratory exchange ratio, factors affecting metabolism, starvation and malnutrition, feeding and satiety centers in the brain, and leptin secretion. The answers to each question are provided at the end.
