WebSep 16, 2024 · Apoptosis is an orderly process in which the cell’s contents break down and are packaged into small packets of membrane for “garbage collection” by immune cells. It contrasts with necrosis (death by injury), in which the dying cell’s contents spill out and cause inflammation. Apoptosis removes cells during development. Table of Contents show WebApoptosis is known as programmed cell death because it’s typically caused by self-generated signals within a cell. It is a natural part of the cell cycle initiated by mitosis in cell reproduction. This process is mediated by caspases, enzymes that exist in all cells, and cleave specific proteins to begin the process of cell death. highview in the woodlands rockford il
