Text Solution

Verified by Experts

The correct Answer is:
C
RQ of malic acid is 1.33. Respiratory Quotient (RO) is the ratio of the volume of `CO_(2)` produced to the volumne of `O_(2)` consumed in respiration over a period of time. RQ is siightly more than unity when organis acids are broken down as respiratory substrates under aerobic conditions, e.g. malic acid.
`underset("Malic acid")(C_(6)H_(6)O)+3O_(2)to4CO_(2)+3H_(2)O`
`RQ=(4CO_(2))/(3O_(2))=1.33`
