Answer:
1. Glycolysis - Option- A, C
2. Electron transport chain -Option-D, E
3.Citric acid (Krebs) cycle- Option-B
Explanation:
1.Glycolysis
Glycolysis is the first phase of the cellular respiration which oxidizes the glucose molecule to pyruvate molecules in ten enzymes catalyzed reaction. The reaction takes place in the cytosol of the cell.
2. Electron transport chain
The last phase of the cellular respiration where the electrons flow or transports through the electron carriers and in last is picked or accepted by the oxygen. The process forms about 24 molecules of ATP through ATP synthesis.
3. Citric acid (Krebs) cycle
The third phase of respiration which forms the reducing equivalents like NADH and FADH₂. The process produces 4 molecules of Carbon dioxide.
