2. COPII vesicles are primarily responsible for protein transport: (A) From Golgi to ER. (B) From trans-Golgi to lysosomes. (C) Between Golgi cisternae. (D) From plasma membrane to early endosomes. (E) From ER to Golgi.

7. What is the role of cytochrome c release during intrinsic apoptosis? (A) It binds directly to pro-caspase-3, causing its activation. (B) It neutralizes IAP proteins like XIAP, freeing caspases from inhibition. (C) It released proteases from the mitochondria to cleave protein targets. (D) It permeabilizes the mitochondrial inner membrane, causing a loss of ATP production. (E) It triggers the formation of the apoptosome with APAF-1, which then activates caspase-9.
