Hsp 70 and Hsp 90 are ____________ involved in the mitochondrial uptak

1.	Hsp 70 and Hsp 90 are ____________ involved in the mitochondrial uptake of proteins.(a) chaperones(b) receptors(c) ligands(d) glycolipidsThis question was addressed to me in quiz.I want to ask this question from Cytoplasmic Membrane Systems topic in division Cytoplasmic Membrane Systems of Cell Biology
Answer» The CORRECT answer is (a) chaperones The best explanation: For uptake into the mitochondria, PROTEINS must be presented to it in an unfolded STATE. MOLECULAR chaperones HSP 70 and Hsp 90 prepare the proteins for mitochondrial uptake by unfolding them.
