The energy yield in terms of ATP is higher in aerobic respiration than during anaerobic respiration. Why is there anaerobic respiration even in organism that live in aerobic condition like human beings and angiosperms ?

Explanation

### Step-by-Step Solution

1. **Understanding Aerobic vs. Anaerobic Respiration**:
- Aerobic respiration occurs in the presence of oxygen and yields a higher amount of ATP (approximately 36-38 ATP molecules per glucose molecule).
- Anaerobic respiration occurs in the absence of oxygen and yields a lower amount of ATP (only 2 ATP molecules per glucose molecule).

2. **Energy Demand in Human Muscles**:
- During intense physical activities, human muscles require a significant amount of energy to function effectively.
