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
A.b) and d) only
B.a) and b) only
C.a) and d) only
D.c) and d) only
Solution
Sol. [Key Concept: Photorespiration — the C₂ (glycolate) pathway]
• Photorespiration can occur in C3 plants.
- In photorespiration, $O_{2}$ is consumed and ${CO}_{2}$ is released.
- Phosphoglycolate is formed as the initial product.
- There is no synthesis of ATP and NADPH in photorespiration.
