Which of the following statements describes a typical feature of protein import into mitochondria?

A. Proteins are imported in a fully folded state

B. Protein import is driven by ATP hydrolysis

C. Protein import involves a chaperone that keeps the protein unfolded in the cytosol

D. The entire process (from signal sequence recognition to signal peptide cleavage) does not require any energy

E. Protein depends on diffusion of proteins through porins, followed by active import into the mito matrix through an aqueous translocation channel

I think it is either C or E...
