Question

Which of the following is true about Peroxisome?

a. Peroxisome is a site for protein translation.
b. Peroxisomal proteins are translated in mitochondria.
c. Proteins transported into the peroxisomes are in native, folded form.
d. Peroxisomal lumen is continuous with ER lumen.

Answer 1

Proteins transported into peroxisomes are in their native, folded form(option C). Peroxisomes carry out lipid biosynthesis, detoxification, and oxidation reactions, housing enzymes crucial for these functions.

Step-by-step explanation:

The correct statement about peroxisomes is that proteins transported into peroxisomes are in native, folded form(OPTION C).

Peroxisomes are involved in processes such as lipid biosynthesis, breaking down of various molecules, detoxifying harmful substances, and oxidation reactions. Unlike protein translation in the rough endoplasmic reticulum (RER), proteins destined for peroxisomes are synthesized in the cytoplasm and maintain their folded structures when transported into the peroxisomes. They contain enzymes, like catalase, which help in neutralizing poisons such as alcohol by producing hydrogen peroxide (H2O2), and then swiftly converting it into water and oxygen to avoid cellular damage.
