In the initial phase of aerobic respiration, one molecule of glucose is broken down into two molecules of pyruvate. What is the net ATP gain?
Q1. In the initial phase of aerobic respiration, one molecule of glucose is broken down into two molecules of pyruvate. What is the net ATP gain?
Answer: 2 ATP
Explanation: Glycolysis yields four ATPs but consumes two, leaving a net gain of two; four represents total production before subtracting investment.
