53. Protein import into peroxisomes exhibits unique characteristics compared to mitochondrial import. Which statement accurately contrasts these two processes?
(A) Both require proteins to be fully unfolded by cytosolic chaperones before translocation.
(B) Mitochondrial import requires a membrane potential, while peroxisomal import is driven by a proton gradient across the single membrane.
(C) The import signal for both organelles is a cleavable N-terminal amphipathic helix recognized by the same class of cytosolic receptors.
(D) Both processes utilize the same family of translocator proteins (TOM/TIM and Pex) that are evolutionarily conserved.
(E) Peroxisomes can import fully folded and even oligomeric proteins, whereas mitochondria require proteins to be unfolded to pass through translocators.
