Answer:

1. Aerobic respiration

2. Anaerobic respiration

3. 36 ATPs

4. 2 ATPs

Explanation:

According to the diagram attached to this question, the process of cellular respiration is described. Based on whether OXYGEN is present or not, cellular respiration can be divided into two:

- Aerobic respiration is the respiration that occurs in the presence of oxygen. As shown in the top process, aerobic respiration starts with glycolysis → krebs cycle → Electron transport chain (ETC). At the end of these three steps, 36 ATP molecules results.

- Anaerobic respiration is the respiration that occurs in the absence of oxygen. As described in the bottom process of the diagram, anaerobic respiration starts with glycolysis and enters alcoholic or lactic acid fermentation depending on which product is formed (alcohol or lactic acid). At the end of the process, only 2 ATP molecules is synthesized.
