How many ATP are produced in the electron transport chain?
Understand the Problem
The question is asking about the number of ATP molecules produced during the electron transport chain, a critical process in cellular respiration. The respondent needs to choose the correct option from the given choices.
Answer
Approximately 30–32 ATP molecules.
The electron transport chain produces approximately 30–32 ATP molecules per glucose molecule.
Answer for screen readers
The electron transport chain produces approximately 30–32 ATP molecules per glucose molecule.
More Information
The range in ATP production (30-32) accounts for variations in different cellular conditions and the energetic efficiency of the coupling of proton gradients to ATP synthesis. Overall ATP production from aerobic respiration includes glycolysis and the citric acid cycle.
Tips
A common mistake is to assume a fixed number of ATP molecules are produced, ignoring variations due to cellular conditions and tissue types.
