Step 1

Cellular respiration is a pathway that breaks the glucose molecule and produces ATP (adenosine triphosphate). ATP is the energy currency of cells. In this process six carbon sugar molecule Glucose is converted into CO2 (carbon dioxide) and H2O (water) in the presence of O2 (oxygen), to yield 36 to 38 molecules of ATP.

Cellular respiration equation is given below:

СН20, + 60, > 6C0, +12H,+364ТР

Step 2

There are four phases are found in cellular respiration:

Glycolysis, pyruvate oxidation, citric acid cycle and oxidative phosphorylation. All stages are described below in different steps:

Step 3

Glycolysis: It is the first phase of cellular respiration. It doesn’t require O2; hence it occurs in all living cells. Glycolysis is takes place in cytoplasm. In this process glucose undergoes in a ten st...
