Q45

Organelles involved in photorespiration are

A.
Mitochondria, chloroplasts and ribosomes
B.
Mitochondria peroxisomes and chloroplasts
Answer
C.
Mitochondria, nucleus and ribosomes
D.
Mitochondria, peroxisomes and glyoxysomes

Answer: Option B

Solution

Answer: Option B
Solution:
Organelles involved in photorespiration are Mitochondria peroxisomes and chloroplasts.
Plant mitochondria also serve a unique role in photorespiration, the conversion of glycine to serine, CO2 and NH3. This respiratory organelle has a major role in photosynthetic carbon and nitrogen metabolism in the leaves of C3 plants.
The most prominent role of peroxisomes in photosynthetic plant tissues is their participation in photorespiration, a process also known as the oxidative C2 cycle or the oxidative photosynthetic carbon cycle.
