In what conformational state do proteins cross the mitochondrial membranes?
A. in fully folded (native) form.
B. bound to an importin recognized by a signal sequence.
C. in unfolded extended form without chaperones.
D. in unfolded extended form attached to Hsp70 chaperones.
Homework Answers
C. in unfolded extended form without chaperones.
Proteins have to become unfolded to cross the mitochondrial membranes. Hsp70 chaperone proteins hold the proteins in extended form for delivery to the mitochondria. But the proteins cross the mitodondrial membrane without any carrier protein and in unfolded state.

Question 78 Which of the following statements about the cytoskeleton is TRUE? All eukaryotic cells have actin, microtubules, and intermediate filaments in their cytoplasm The cytoskeleton provides a rigid and unchangeable structure important for the shape of the cell. The three cytoskeletal filaments perform distinct tasks in the cell and act completely independently of one another Actin filaments and microtubules have an inherent polarity, with a plus end that grows more quickly than the minus end С.
