Question

R.Q. of sprouting potato is?

• A. $1$
• B. $>1$
• C. $<1$
• D. Zero

Answer 1

The correct option is A $1$

Respiratory quotient is the ratio of the volume of carbon dioxide produced to the volume of oxygen consumed in respiration over a period of time. Its value can be one, zero, more than 1 or less than one.

RQ = Volume of CO${}_2$ evolved/Volume of O${}_2$ absorbed.

Respiratory quotient is equal to unity if carbohydrates are the respiratory substrate and the respiration is aerobic.

C${}_6$H${}_{1}2$O${}_6$ + 6O${}_2$ $\to$ 6CO${}_2$ + 6H${}_2$O

RQ = 6CO${}_2$/6O${}_2$ = 1

Since, sproutingpotato consists of carbohydrates, the respiratory quotient (R.Q) is 1

So the correct option is '1'.
