NEET Previous Year Question
Which of the metabolites is common to respiration mediated breakdown of fats, carbohydrates
and proteins?
Topic: NEET PYQ
Answer: D. Full step-by-step solution below.
- AGlucose 6 – phosphate
- BFructose 1,6–bisphosphate
- CPyruvic acid
- DAcetyl-CoA
Correct answer: D
Solution
(d) During respiration:Carbohydrates → glucose → pyruvate → acetyl-coa
Fats → fatty acids → acetyl-coa
Proteins → amino acids → acetyl-coa (after deamination)
Thus, acetyl-coa is the common metabolite where breakdown products of carbohydrates, fats, and proteins enter respiration.
