Question

The peroxisomes are associated with the phenomenon of

• A. Oxidative anabolism
• B. Degradation of H${}_2$O
• C. Anaerobic respiration
• D. Photorespiration and degradation of H${}_2$O${}_2$

Answer 1

The correct option is D Photorespiration and degradation of H${}_2$O${}_2$

The peroxisomes are associated with the phenomenon of photorespiration and degradation of H${}_2$O${}_2$. Certain enzymes within the peroxisome, by using molecular oxygen, remove hydrogen atoms from specific organic substrates, in an oxidative reaction, producing hydrogen peroxide.
Photorespiration involves a complex network of enzyme reactions that exchange metabolites between chloroplasts, leaf peroxisomes and mitochondria.
