WebCaspases are central effectors of apoptosis. Cells undergo apoptosis through two major pathways, namely the extrinsic pathway (death receptor pathway) or the intrinsic pathway (the mitochondrial pathway). Finally, the contents of dead cells are packaged into apoptotic bodies, which are recognized by neighboring cells or macrophages and cleared ... WebProgrammed cell death (PCD) is critical for the survival of eukaryotic, multicellular organisms. For example, it plays critical roles in morphological development where PCD is …

Solved How is this form of programmed cell death a process

WebCell death was once believed to be the result of one of two distinct processes, apoptosis (also known as programmed cell death) or necrosis (uncontrolled cell death); in recent years, however, several other forms of cell death have been discovered highlighting that a cell can die via a number of differing pathways. Apoptosis is characterised by ... WebA cell reproduces by performing an orderly sequence of events in which it duplicates its contents and then divides in two.
