Question

A cell organelle that is essential for photorespiration is

• A. Ribosome.
• B. Dictyosome.
• C. Peroxisome.
• D. Glyoxysome.

Answer 1

The correct option is C Peroxisome.

Photorespiration is a wasteful process, which occurs in $C_3$ plants in presence of light. In the photorespiratory pathway, there is neither synthesis of sugars, nor of ATP. Rather it results in the release of $C{O}_2$ with the utilisation of ATP. In the photorespiratory pathway there is no synthesis of ATP or NADPH. Therefore, photorespiration is a wasteful process. This process occurs in chloroplast, peroxisomes and mitochondria.
