This process can be induced by an intrinsic pathway in response to cellular stress or by extrinsic signals. For 10 points each:
[10m] Name this process which involves the action of caspases and membrane blebbing.
ANSWER: apoptosis
[10e] These organelles play an important role in apoptosis, including the release of cytochrome c from their outer membrane. Cellular respiration takes place in these organelles.
ANSWER: mitochondria [or mitochondrion]
[10h] This protein can initiate cytochrome c release by binding to the mitochondrial membrane protein Bak. The stability of this proline-rich protein is regulated by M.d.m.2.
ANSWER: p53 [or tumour protein p53; or cellular tumour antigen p53; or phosphoprotein p53; or tumour suppressor p53; or antigen NY-CO-13; or transformation-related protein 53; or TRP53]
