In respiration from 180 g of glucose which of the following is formed.

A

`264 gm CO_(2) + 190 gm H_(2)O + 391 ` Kcal

B

`264 gm CO_(2) + 108 gm H_(2)O + 686 ` Kcal

C

`390 gm CO_(2) + 108 gm H_(2)O + 686 ` Kcal

D

`390 gm CO_(2) + 264 gm H_(2)O + 391 ` Kcal

Text Solution

Verified by Experts

The correct Answer is:
B
In respiration, from 180 gm of glucose 264 gm `CO_(2) `+ 108 gm `H_(2)O` + 686 Kcal energy is formed `C_(6)H_(12)O_(6)+6O_(2) to 6H_(2)O + 686` Kcal
Atomic weight of `C=12, H=1,)=16`
`C_(6)H_(12)O_(6)=(12xx6+12xx1+16xx6)`
`=180` gm
`6CO_(2)=6(12+6xx2)`
=264 gm
`6H_(2)O=6(2xx1+16) `
`=108` gm
`therefore ` From 1 molecular or 180 gm of glucose , through respiration , 264 gm `CO_(2)` , 108 gm `H_(2)O` and 686 Kcal energy are formed.
