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. [1] Biochemical events lead to characteristic cell changes ( morphology) and death. [2]
Apoptosis - Definition and Importance
WEBMar 20, 2024 · Apoptosis comes from the Greek words “apo” (away from) and “ptosis” (falling), literally meaning the “falling off” of cells. It is a form of programmed cell death, where cells dismantle themselves in a controlled and regulated manner. This mechanism is crucial for maintaining cellular integrity and organismal homeostasis.

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.

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] Go to:

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.
