In respiration from 180 ~g of glucose which of the following is formed?
Options
- A264gm CO C ₂+190 gm H ₂ O +391 Kcal
- B264 gm CO +108 gm H H ₂ O +686 Kcal
- C390 gm CO +108 gm H H ₂ O +686 Kcal
- D390 gm CO ₂+264 gm H ₂ O +391 Kcal
Correct answer
B. 264 gm CO +108 gm H H ₂ O +686 Kcal
Step-by-step solution
In respiration, from 180 gm of glucose 264 gm CO CO ₂+108 gm H ₂ O +686 Kcal energy is formed. C ₆ H ₁₂ O ₆+6 O ₂ 6 CO ₂+6 H ₂ O +686 Kcal Atomic weight of C =12, H =1, O =16 aligned C ₆ H ₁₂ O ₆ & =(12 6+12 1+16 6) & =180 gm 6 CO ₂ & =6(12+16 2) & =264 gm 6 H ₂ O & =6(2 1+16) & =108 gm aligned From 1 molecule or 180 gm of glucose, through energy are formed.
