Question

Even though peroxisomes, chloroplasts and mitochondria import proteins via a translocon complex they do it differently. Which of the following is NOT TRUE about protein import into specialized organelles?

A. peroxisome uses a single translocator complex because they are single membrane compartments while chloroplasts and mitochondria use two translocator complexes to transport proteins across two membrane lipid bilayers

B. chloroplasts and mitochondria denature proteins while transporting them across TOC/TIC or TOM/TIM complexes

C. chloroplast targeted proteins sometimes have two signal peptides one to deposit the protein in the stroma and another to further transport the protein to the thylakoid membrane space

D. in mitochondria if a protein has one or more transmembrane domains it is not released in the mitochondrial matrix space but rather diverted to the mitochondrial inner membrane

E. peroxisome importer proteins (POC/PIC) denature cargo proteins while importing proteins across a double layer membrane structure

Explanation / Answer

i am not 100% sure but i think E would be the answer that is peroxisome importer proteins (POC/PIC) denature cargo proteins while importing proteins across a double layer membrane structure.
