Place the three stages of aerobic cellular respiration in the correct order from 1 to 3. electron transport chain glycolysis citric acid cycle

The aerobic respiration takes place in most of the eukaryotic organisms.

The aerobic respiration utilizes glucose and oxygen to generate the ATP molecules.

It takes place in three steps:

1. Glycolysis: in this the glucose is converted into pyruvate.

2. Krebs Cycle or citric acid cycle: in this the pyruvate undergoes sequence of reactions and forms NADH and FADH2. ATP is also generated in this step.

3. Electron transport chain: In this the NADH and FADH2 are used to generate more ATP molecules.

Hence, the correct order of the aerobic respiration is :

1. Glycolysis.

2. Citric acid cycle

3. electron transport chain.
