Which of the following option is correct for the given statements , X, Y and Z Statements X - R.Q. of fat containng palmatic acid is less than one, whereas R.Q. of glucose is 1
Statement Y - Fat containing palmatic acid need less `O_(2)` for respiration and glucose need more oxygen for respiration
Statement Z - fat containing palmatic acid has much less oxygen in its constituion as compared to glucose.

Options

A. Statement X, Y and Z are correct and statement Y and Z are correct explanation for X.
B. Statement X and Y are correct and statement Z is incorrect statement Y is correct explanation for X
C. Statement X and Z are correct and statement Y is incorrect statement Z is correct explanation for X
D. Statement X and Z are incorrect and statement Y is correct.

Answer

C

Explanation

Carbohydrate
`C_(6)H_(12)O_(6)+6O_(2)rarr6CO_(2)+6H_(2)O+`Energy
`RQ=(6CO_(2))/(6O_(2))=1`
Fats: The value of RQ is less than 1. this would mean that there is much less oxygen in the constituition of fat as compared to that in carbohydration. thus. they need more `O_(2)` for respiration. As an example. the equation for respiration of Tripalmitin is as under
`2(C_(51)H_(98)O_(2)rarr102CO_(2)+98H_(2)O)` energy `RQ=(102CO_(2))/(145O_(2))=0.7`.
