What is aerobic respiration?

A Partial oxidation of glucose
B Incomplete oxidation of glucose
C Complete oxidation of organic substances
D Complete oxidation of only glucose

Correct Answer: Complete oxidation of organic substances

Aerobic respiration is the complete oxidation of organic substances which occur in the presence of oxygen. It is an energy yielding process as a large amount of energy in the form of ATP is released. Water and carbon dioxide are also released as its by-products.
