Question

In aerobic respiration, how many ATP molecules are produced by the oxidation of one glucose molecule?

Answer 1

Aerobic respiration:

• Aerobic respiration takes place in the presence of oxygen.
• Aerobic respiration is carried in the cytoplasm and mitochondria of the plant cell.
• Gases are exchanged in aerobic respiration.

ATP molecules produced by the oxidation of 1 glucose molecule:

• In aerobic respiration, there is complete oxidation of glucose into carbon dioxide and water.
• Energy is also released, which is expressed in the form of ATP.
• The glucose reacts in the presence of six oxygen molecules giving six carbon dioxide molecules and six water molecules, and energy is released in the form of ATP.
• The major three steps of aerobic respiration that produce ATP are Glycolysis (2 ATP), Krebs cycle( 2 ATP), and Electron Transport Cycle ( 2.5 ATP/NADH and 1.5 ATP/FADH₂ resulting in 34 ATP ).
