This often occurs for the greater good of the whole organism, such as when the cell's dna has become damaged and it may become cancerous. Signal transduction is the process of transferring a signal throughout an organism, especially across or through a cell The granzymes then initiate apoptosis by activating apoptotic enzymes called caspases, leading to cell death

Natural killer cells secrete granules to kill cancer cells regulation of natural killer cells as they roam the tissues of the body, natural killer cells constantly encounter other cells.
The cell cycle is a cycle of stages that cells pass through to allow them to divide and produce new cells
It is sometimes referred to as the “cell division cycle” for that reason. The rough endoplasmic reticulum (rough er) is a part of the endomembrane system of the cell and a subset of the endoplasmic reticulum (er) This organelle is primarily concerned with the synthesis, folding and modification of proteins, especially those that need to be delivered to different organelles within the cell, or secreted from the cell. Cellular differentiation, or simply cell differentiation, is the process through which a cell undergoes changes in gene expression to become a more specific type of cell
Phagocytosis, or “cell eating”, is the process by which a cell engulfs a particle and digests it Once inside, the granzymes initiate apoptosis (programmed cell death) which kills the cell and any pathogens it contains Cytotoxic t cells use perforin and granzymes to destroy target cells Cytolysis, also known as osmotic lysis, occurs when a cell bursts and releases its contents into the extracellular environment due to a great influx of water into the cell, far exceeding the capacity of the cell membrane to contain the extra volume.
Saccharomyces cerevisiae (also known as baker's yeast or brewer's yeast) is a unicellular fungus responsible for alcohol production and bread formation.
