Apoptosis - Wikipedia
WEBApoptosis (from Ancient Greek: ἀπόπτωσις, romanized: apóptōsis, lit. 'falling off') is a form of programmed cell death that occurs in multicellular organisms and in some eukaryotic, single-celled microorganisms such as yeast. Biochemical events lead to characteristic cell changes and death.
Apoptosis (article) | Developmental biology | Khan Academy
WEBApoptosis is an orderly process in which the cell’s contents are packaged into small packets of membrane for “garbage collection” by immune cells. Apoptosis removes cells during development, eliminates potentially cancerous and virus-infected cells, and maintains balance in the body. Video: Overview of apoptosis. Apoptosis See video transcript.

WEBLast Updated: June 6, 2017. Apoptosis Definition. Apoptosis is a process that occurs in multicellular when a cell intentionally “decides” to die. 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.

WEBApr 4, 2024 · Apoptosis, in biology, a mechanism that allows cells to self-destruct when stimulated by the appropriate trigger. Apoptosis can be triggered by mild cellular injury and by various factors internal or external to the cell; the damaged cells are then disposed of in an orderly fashion.

WEBApr 14, 2023 · Apoptosis is an ATP-dependent, enzyme-mediated, genetically programmed death of cells that are no longer needed or are a threat to the organism. Apoptosis results when the cytoskeleton (by proteases) and DNA (by endonucleases) break down. Both are mediated by caspases.[1][2][3]

WEBIn multicellular organisms, cells that are no longer needed or are a threat to the organism are destroyed by a tightly regulated cell suicide process known as programmed cell death, or apoptosis. Apoptosis is mediated by proteolytic enzymes called caspases, which trigger cell death by cleaving specific proteins in the cytoplasm and nucleus.

WEB4 days ago · Apoptosis is the process of programmed cell death. It is used during early development to eliminate unwanted cells; for example, those between the fingers of a developing hand. In adults, apoptosis is used to rid the body of cells that have been damaged beyond repair. Apoptosis also plays a role in preventing cancer.
