Match the items of Column A with items of Column B. Column A Column B (i) Energy currency (A) Haemoglobin (ii) Powerhouse of the cell (B) Lactic acid (iii) Respiratory pigment (C) ATP (iv) Exchange of gases (D) Mitochondria (v) Muscular cramps (E) Alveoli

(i)-(C) Adenosine triphosphate (ATP) is the energy currency of the cell as it is the molecule that all living organisms use for energy. (ii)-(D) Mitochondria are called a powerhouse of the cell as the energy required for various life processes is released by it in the form of ATP. (iii)-(A) Haemoglobin is a respiratory pigment as it increases the oxygen-carrying capacity of the blood. (iv)-(E) Exchange of gasses takes place in the alveoli of lungs. (v)-(B) Muscular cramps are the result of the accumulation of lactic acid. The anaerobic breakdown of glucose leads to the formation of lactic acid in the muscles.
