1. Energy is released during the oxidation of compounds in respiration. How is this energy stored and released as and when it is needed?

Solution:

Adenosine Triphosphate (ATP) is used to store the energy created during the oxidation of chemicals in respiration. Adenosine triphosphate (ATP) is stored as chemical bonds.

ADP + IP + energy → ATP (ADP = Adenosine Diphosphate and IP = Inorganic phosphorous)

When energy is required then, this bond energy is broken and utilised

ATP → ADP + IP + energy.
