3. respiration and exhalation.
4.phosphorylation and fermentation.

Answer 1

2. respiration and fermentation

Answer 2

The appropriate answer is 2. Respiration and fermentation. Respiration is the process by which living organisms get energy from food (sugars). Oxygen is added to glucose and in the process water, carbon dioxide and energy is produced. Fermentation also produces energy. The process occurs without oxygen but produces less energy than respiration.
