RQ of malic acid is

  • A
    $1.9$
  • B
    $1.49$
  • Correct answer
    C
    $1.33$
  • D
    $1$

Solution

RQ of malic acid is 1.33. Respiratory Quotient (RQ) is the ratio of the volume of $\mathrm{CO}_2$ produced to the volume of $\mathrm{O}_2$ consumed in respiration over a period of time. RQ is slightly more than unity when organic acids are broken down as respiratory substrates under aerobic conditions, e.g. malic acid. Figure

Hence, the correct answer is option: 'C'.
