Which of the following statements regarding photorespiration are correct ? (a) Do not occur in C3 plants (b) CO₂ is consumed and O₂ 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

Correct answer

C. (c) and (d) only

Step-by-step solution

Photorespiration occurs primarily in C3 plants, making statement (a) incorrect. During photorespiration, O₂ is consumed and CO₂ is released, making statement (b) incorrect. In the first step of photorespiration, RuBP binds with O₂ 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) a
