Question

___ respiration takes place in the muscle cells of man.

Answer 1

Respiration:

1. The biochemical process that involves the breakdown of a complex organic compound into simpler elements to release energy is called respiration.
2. Glucose is a complex organic compound that may be broken down in the presence or absence of oxygen.

Anaerobic respiration:

1. Anaerobic respiration takes place in the absence of oxygen.
2. This process releases energy used by the muscle cells for contraction.
3. The reaction of anaerobic respiration in the muscle cells can be stated as, $\mathrm{Glucose}\to \mathrm{Pyruvate}\stackrel{\mathrm{in}\mathrm{the}\mathrm{absence}\mathrm{of}\mathrm{oxygen}}{\to }\mathrm{Lactic}\mathrm{acid}+\mathrm{Energy}$

Anaerobic respiration takes place in the muscle cells of man.
