Question

R.Q. of a germinating ground nut and castor seed is

• A. 1
• B. < 1.
• C. > 1.
• D. 0

Answer 1

The correct option is B < 1.

The respiratory quotient depends upon the type of respiratory substrate used during respiration. When fats are used in respiration, the RQ is less than 1. Groundnut and castor seeds are fats storing seeds, the stored fats are mobilised during their seed germination. Hence, the RQ value is less than one for germinating groundnut and castor seeds.
