The Krebs cycle produces less atp as compared to the electron transport chain.
Answer: Option 3
Explanation:
Electron transport chain is the phase that produces the most energy in the mitochondria. Though both the process of krebs cycle and electron transport chain takes place in mitochondria but during electron transport chain 34 ATP molecules are formed whereas Krebs cycle produces only 2 Atp. NADH is produced in krebs cycle and these NADH is converted into ATP in electron transport chain inside mitochondria.
