Answer:
Option B, The electron transport chain
Explanation:
The process of respiration involves four major steps in the following order –
a) Glycolysis
b) Pyruvate processing
c) Krebs cycle
d) Electron Transport chain
In the glycolysis stage, glucose is broken down into pyruvate. In the next stage, pyruvate is processed to release CO2 and acetyl CoA. In the third stage i.e Krebs cycle acetyl CoA is oxidized to produce CO2, ATP, NADH and FAD is reduced to FADH2 and in the last stage electrons released from NADH and FADH2 flows across the membrane to make ATP.
