Final answer:
The two apoptotic Bcl2 proteins important in the process of programmed cell death, or apoptosis, are Bak and Bax.
Step-by-step explanation:
The two apoptotic Bcl2 proteins are Bak and Bax. These proteins are crucial components of the outer mitochondrial membrane channels that play a significant role in apoptosis by allowing the release of cytochrome C into the cytosol, leading to the activation of caspases that drive the cell through the apoptosis process.
