Questions & Step-by-Step Solutions

What is the net ATP yield from one molecule of glucose during glycolysis?
  • Step 1: Understand that glycolysis is the first step in breaking down glucose for energy.
  • Step 2: Know that one molecule of glucose is converted into two molecules of pyruvate during glycolysis.
  • Step 3: During this process, a total of 4 ATP molecules are produced.
  • Step 4: However, 2 ATP molecules are used up in the early steps of glycolysis.
  • Step 5: To find the net yield, subtract the 2 ATP used from the 4 ATP produced.
  • Step 6: The result is 2 ATP, which is the net yield from one molecule of glucose during glycolysis.
