Question

9. Which of the following is a FALSE statement about the proteasome? a. It is triggered to act by the addition of a ubiquitin to a protein. b. Since degradation happens within the proteasome, general proteolysis of all cytosolic proteins is avoided. c. Ubiquitin is degraded along with the protein it tags. d. It serves as a mechanism to remove damaged proteins from the cell, or proteins that signaling processes have triggered the cell to remove. e. All of the above (A, B, C, and D) are true, so there is no false answer.
