Question

The function of peroxisomes is :

• A. $H_2{O}_2$ destruction
• B. conversion of fats to carbohydrates
• C. detoxification of heavy metals
• D. oxidation phosphorylation

Answer 1

Answer: (A)

The function of peroxisomes is $H_2{O}_2$ destruction.
Peroxisomes are organelles containing a few flavoprotein oxidases which use molecular oxygen and produce $H_2{O}_2$ e.g., D-amino acid oxidase.
Peroxisomes also contain peroxidases which utilize the $H_2{O}_2$ formed for other oxidation reaction.
The $H_2{O}_2$ synthesized and cleaved in the peroxisane.
$2H_2{O}_2\stackrel{\text{ catalase }}{\to }2H_{2}O+O_2$
The function of mitochondria is oxidation phosphorylation.
The function of liver is conversion of fats to carbohydrates with the help of emulsiflcation.
The function of endoplasmic reticulum is detoxification of heavy metals.
