Which of the following statements is incorrect?
(1) Glucose is the favoured substrate for respiration
(2) All carbohydrates are usually first converted into glucose before they are used for respiration
(3) Other respiratory substrates are also respired but they do not enter the respiratory pathway at very first step
(4) Fats directly enter the respiratory pathway
The individual amino acid enter the respiratory pathway at
(1) Within Krebs’ cycle
(2) As Pyruvate or Acetyl CoA
(3) As PGAL
(4) Both A and B

(1) Acetyl CoA
(2) PGAL
(3) BPGA
(4) Pyruvic Acid
Statement - 1 : Respiration is amphibolic pathway.
Statement - 2 : Pure fat & pure protein can never be
respiratory substrate.
Option :
1. Only second statement is correct.
2. Both statements are correct.
3. Neither first nor second is correct.
4. Only first statement is correct
