How does the body of a runner keep up with the demand for energy when cellular oxygen levels are low?

through anaerobic respiration in the cytoplasm

through ATP produced directly from sunlight

through aerobic respiration in the plasma membrane

through energy production in the mitochondria

The correct answer is through anaerobic respiration in the cytoplasm.

Explanation:

Cellular respiration is of 2 types

1 Aerobic respiration Respiration that require oxygen to occur

2 Anaerobic respiration Respiration that do not requires oxygen.

During low oxygen level the body of runner keep up with the demand for energy by undergoing anaerobic respiration which includes Glycolysis.

During anaerobic condition the functionally active body cells undergo glycolysis and with each glycolysis 2 molecules of ATP are generated which can some how boost the energy supply within runner"s body.
