Question

Which out of the following statements is incorrect?

• A. The breakdown product of glucose which enters into mitochondrion during aerobic respiration is pyruvic acid generated in the cytosol.
• B. When the electrons pass from one carrier to another via complex I to IV in the electron transport chain, they are coupled to ATP synthase (Complex V) for the production of ATP from ADP and Pi.
• C. The ratio of volume of $O_2$ consumed in respiration to the volume of ${CO}_2$ evolved is called as the respiratory quotient (RQ).
• D. Compensation point is the point reached in plant when rate of photosynthesis is equal to the rate of respiration.

Answer 1

Answer: (C)

The ratio of volume of $O_2$ consumed in respiration to the volume of ${CO}_2$ evolved is called as the respiratory quotient (RQ).

The respiratory quotient can be defined as the ratio of the volume of carbon dioxide evolved to that of oxygen consumed by an organism, tissue, or cell in a given time.

So, the correct option is 'The ratio of volume of

O2O2 consumed in respiration to the volume of CO2CO2 evolved is called as the respiratory quotient (RQ)'.
