In the given equation below, identify the compound which is being oxidized and calculate the R.Q. of the same. 2 C 51 H 98 O 6 + 145 O 2 → 102 C O 2 + 98 H 2 O + e n e r g y

Options

  1. APalmitin, R.Q. = 0.9
  2. BTripalmitin, R.Q. = 0.7
  3. CPalmitin, R.Q. = 1
  4. D​Tripalmitin, R.Q. = 0.2

Correct answer

B. Tripalmitin, R.Q. = 0.7

Step-by-step solution

When fats are used in respiration, the RQ is less than 1. Calculations for fatty acid, tripalmitin, if used as a substrate is shown: Thus, R.Q. = 0.7
