Which of the following statements regarding photorespiration are correct ?
(a) Do not occur in C3 plants
(b) CO is consumed and O is generated
(c) Phosphoglycolate is formed
(d) No synthesis of ATP and NADPH
Choose the correct answer from the options given below :
(a) Do not occur in C3 plants
(b) CO is consumed and O is generated
(c) Phosphoglycolate is formed
(d) No synthesis of ATP and NADPH
Choose the correct answer from the options given below :
Options
- A(a) and (b) only
- B(a) and (d) only
- C(c) and (d) only
- 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, O is consumed and CO is released, making statement (b) incorrect.
In the first step of photorespiration, RuBP binds with O 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
During photorespiration, O is consumed and CO is released, making statement (b) incorrect.
In the first step of photorespiration, RuBP binds with O 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
