Aerobic respiration takes place in the mitochondria in the presence of oxygen. Pyruvic acid is converted into carbon dioxide, and water thus releasing a lot of energy. (ii) Anaerobic respiration takes place in the cytoplasm in the absence of oxygen.

Answer 2

Explanation:

The three pathways of breakdown of glucose

1. Anaerobic respiration.The anaerobic respiration takes place in the absence of oxygen

2. Aerobic respiration.In aerobic respiration,breakdown of pyruvate takes place in the presence of oxygen to give rise to 3 molecules of carbon dioxide and water.

3. Lack of oxygen
