A yeast cell metabolizes one molecule of glucose through glycolysis. What is the net gain of ATP molecules produced through substrate-level phosphorylation?
Q1. A yeast cell metabolizes one molecule of glucose through glycolysis. What is the net gain of ATP molecules produced through substrate-level phosphorylation?
Answer: 2 ATP
Explanation: Glycolysis produces 4 ATP but consumes 2, resulting in a net gain of 2; 36-38 ATP is the total aerobic yield.
