Questions & Step-by-Step Solutions
What is the net gain of ATP from one molecule of glucose during aerobic respiration? (2023)
Step 1: Understand that glucose is a sugar that cells use for energy.
Step 2: Know that aerobic respiration is a process that uses oxygen to convert glucose into energy.
Step 3: Recognize that during aerobic respiration, glucose is broken down in several stages: glycolysis, the Krebs cycle, and the electron transport chain.
Step 4: In glycolysis, 2 ATP are produced from one glucose molecule.
Step 5: In the Krebs cycle, 2 more ATP are produced.
Step 6: The electron transport chain produces the most ATP, around 26-28 ATP.
Step 7: Add the ATP produced from all stages: 2 (glycolysis) + 2 (Krebs cycle) + 26-28 (electron transport chain) = 30-32 ATP.
Step 8: Conclude that the net gain of ATP from one molecule of glucose during aerobic respiration is approximately 30-32 ATP.
