ICSE Class 9 Biology Chapter 7 Revision Notes: Respiration in Plants

The process which helps in releasing of energy from cells of the body is respiration. It is a catabolic process.

Glycolysis is the metabolic process that serves as the foundation for both aerobic and anaerobic cellular respiration. In glycolysis, glucose is converted into pyruvate. Glucose is a six- membered ring molecule found in the blood and is usually a result of the breakdown of carbohydrates into sugars.

Aerobic Respiration:
The breakdown of glucose in cells in the presence of oxygen is called aerobic respiration. Here is the word equation for aerobic respiration. Energy is put in brackets because it not a substance:

glucose + oxygen → carbon dioxide + water (+ energy)
Example: C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP (energy currency of cell)

ATP (Adenosine triphosphate) undergoes hydrolysis to give adenosine diphosphate (ADP), inorganic phosphorus, and energy.

One mole of glucose yields 38 molecules of ATP on complete oxidation.

Breakdown of glucose occurs in 2 major events which are controlled by enzymes.
