NEET Botany Question (2026) — Solution

Question

Which of the following statements regarding photorespiration are correct ? (a) Do not occur in C3 plants (b) CO_2 is consumed and O_2 is generated (c) Phosphoglycolate is formed (d) No synthesis of ATP and NADPH Choose the correct answer from the options given below :

Options

  1. A. (a) and (b) only
  2. B. (a) and (d) only
  3. C. (c) and (d) only
  4. D. (b) and (d) only

Answer

C. (c) and (d) only

Step-by-step solution

Photorespiration occurs primarily in C3 plants, making statement (a) incorrect. During photorespiration, O_2 is consumed and CO_2 is released, making statement (b) incorrect. In the first step of photorespiration, RuBP binds with O_2 to form one molecule of phosphoglycerate and one molecule of phosphoglycolate, making statement (c) correct. Photorespiration is a wasteful process where there is no synthesis of ATP or NADPH; instead, it consumes ATP, making statement (d) correct. Therefore, only statements (c) and (d) are correct. Answer: (c) and (d) only
