Question

Organelle associated with photorespiration is
(a) Ribosome
(b) Peroxisome
(c) Nucleosome
(d) Mesosome

Answer 1

Dear Student,

◆ Answer - (b)

• Organelle associated with photorespiration is Peroxisome.

● Explanation -

• Peroxisomes carry out oxidative photosynthetic carbon cycle during the process of photorespiration.

● Extra information -

• In photorespiration, RuBisCO enzyme takes up oxygen and carbon dioxide is liberated in air.
• It is said to be wasteful reaction As carbon dioxide (which is required for photosynthesis) is wasted here.

Thanks dear. Hope this helps you...

Answer 2

Organelle associated with photorespiration is Peroxisome.

Option: B

Explanation:  

• There are three organelle associated with photorespiration. These includes mitochondria, chloroplast and peroxisome.  

• It occurs in plants even when the concentration of carbon dioxide is low in daylight. Then in the presence of light plants respire using oxygen to release carbon dioxide.  

• It begins when oxygen reacts with rubisco in the chloroplast of the cell. Then the product formed enters the peroxisome in the form of glycine.  

• The glycine gets converted into serine in the mitochondria. This is converted into serine which reenters the chloroplast.
