Corrected flow-chart: Process of obtaining the energy: Carbohydrates: Carbohydrates like glucose are oxidized to pyruvic acid. Pyruvic acid is converted to acetyl-co-enzyme-A which is oxidized through Kreb's cycle. The molecules of NADH 2 produced during this are oxidized through electron transfer chain reaction and finally, energy is obtained.
