Question

Which of the following statements is incorrect regarding respiration?

A

Energy of oxidation-reduction is utilised for phosphorylation

B

Oxygen acts as the final hydrogen acceptor

C

The photo-oxidative energy is utilised for production of proton gradient required for phosphorylation

D

The role of oxygen is limited to the terminal stage of the respiration process

Step-by-Step Solution

statements A, B, and D are correct regarding respiration:

  • Statement A: In respiration, the energy of oxidation-reduction is utilised for phosphorylation (Oxidative Phosphorylation).
  • Statement B: Oxygen acts as the final hydrogen acceptor.
  • Statement D: The role of oxygen is limited to the terminal stage of the process.
  • Statement C is incorrect for respiration. The text distinguishes respiration from photophosphorylation, stating that in photophosphorylation, light energy (photo-oxidative) is utilised for the production of the proton gradient, whereas in respiration, it is the energy of oxidation-reduction.

Exam Context & Concepts Covered

This question aligns with the NEET BIOLOGY syllabus, specifically targeting concepts from Respiration in Plants. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
