Question

What would likely happen to a cell treated with a compound that causes lysis (breakage) of peroxisomal membranes?

A. Proteins would leak out and fail to be secreted.

B. Ca++ would leak out and trigger exocytosis.

C. Proteins in the cytoplasm would be damaged from the release of free radicals.

D. Probably not much, because peroxisomes have porous membranes anyway.

C. Proteins in the cytoplasm would be damaged from the release of free radicals.

D. Probably not much, because peroxisomes have porous membranes anyway.

The answer is C. Proteins in the cytoplasm would be damaged from the release of free radicals.

Peroxisomes contain free radicals that can oxidize proteins and can damage them when their membranes are lysed.
