Assertion (A): Humans are not truly aerobic.  

Reason (R): They produce lactic acid anaerobically.  

Answer

 

  • 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
