Question

the signal for apoptosis can come from outside or inside the cell. Give one example when the signal comes from outside the cell and two examples of cellular occurrences that would prompt an apoptosis signal from inside the cell

Answer 1

Outside cell:Signals coming from other cells

Inside cell: Cell stress, weak external signals

Step-by-step explanation:

Apoptosis can be intrinsic or extrinsic. Where it is intrinsic, signal for Apoptosis comes from within the cell(in this case cell stress or weak external signal) apoptosis; death of cell occurs. Extrinsic signal occurs where the cell gets signals from other cells and apoptosis takes place.
