Choose the statements that correctly describe the structure and function of proteasomes. a. The proteasome hydrolyzes the unfolded proteins to free amino acids, which are then recycled.
b. The 26S proteasome unit is composed of a 12S component and a 14S component.
c. One of the 19S regulatory particles cleaves ubiquitin from the protein.
d. Proteasomes would not be expected to use ATP to degrade small, unfolded peptides.
e. The proteolytic sites of the proteasome are located at the middle of the 20S core.
f. Proteasomes degrade proteins to small peptides.
