Assertion (A): Humans are not truly aerobic.
Reason (R): They produce lactic acid anaerobically.
- Humans are aerobically respiring animals
- Sometimes anaerobic respiration takes place in tissues like skeletal muscles , when their oxygen needs are not being met.
Therefore, the muscles respire anaerobically and produce lactic acid from glucose, but ONLY when oxygen is lacking.
- The assertion is True
- The reason is True
The reason is the correct explanation of the assertion
So, the correct option is (b)
