Question

Explain the process of cellular respiration.

Answer 1

Cellular respiration is the process of oxidizing food molecules, like glucose, to carbon dioxide and water to release energy.
C6H12O6+6O2+6H2O→12H2O+6CO2+Energy

The energy released is trapped in the form of ATP for use by all the energy-consuming activities of the cell.

The process occurs in two phases:
1) Glycolysis, the breakdown of glucose to pyruvic acid
2) The complete oxidation of pyruvic acid to carbon dioxide and water.
In eukaryotes, glycolysis occurs in the cytosol. The remaining processes take place in mitochondria.
