The products of the electron transport chain (ETC) primarily include:
- ATP (as a result of oxidative phosphorylation)
- H2O (water, which is formed when electrons reduce oxygen)
The other options listed (NADH, O2, CO2, Pyruvate) are not direct products of the ETC:
- NADH is produced in earlier stages of cellular respiration (like glycolysis and the citric acid cycle).
- O2 is the final electron acceptor but is not a product.
- CO2 is produced during the citric acid cycle (not the ETC).
- Pyruvate is produced in glycolysis.
So, the correct answers are:
- ATP
- H2O
- ATP (as a result of oxidative phosphorylation)
- H2O (water, which is formed when electrons reduce oxygen)
