Question
Observe the image and analyze the portion asked in the image that is produced in the Krebs cycle.
- Oxygen and NADH
- FADH2 and NADH
- FADH2 and Water
- NADH and carbon dioxide
Hint:
- ATP and NADH are formed in Krebs cycle
The correct answer is: FADH2 and NADH
- ATP and NADH are formed in the Krebs cycle
- This then enters the electron transport chain where these molecules are reduced and movement of electrons in the chain is coupled to ATP synthesis
