What is a apoptosis in biology?
(A-pop-TOH-sis) A type of cell death in which a series of molecular steps in a cell lead to its death. This is one method the body uses to get rid of unneeded or abnormal cells.
What is the best definition of apoptosis?
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.
Which of the following defines apoptosis quizlet?
What is apoptosis? Apoptosis is the default pathway of a cell that leads to programmed cell death. It is caused by cell damage, infection of developmental transformation.
What is apoptosis in pathology?
Apoptosis (programmed cell death) occurs normally for maitenance of tissue homeostasis and play an important role in morphogenesis, embriogenesis and tissue growth. On the other hand, apoptosis may be involved in different pathological processes such as malignancy, infectious diseases and autoimmune disorders.
What is meant by apoptosis Mcq?
Apoptosis is programmed cell death. Explanation: Apoptosis is the programmed cell death in which a cascade of events leads to the death of the cell.
What is apoptosis quizlet Chapter 11?
Apoptosis -> Induced by internal stress signals and occurs during neurodevelopment to remove excessive cells.
What is the purpose of apoptosis quizlet?
– Apoptosis eliminates damaged cells, especially those possessing DNA damage that can result in cancer.
What is apoptosis and why might it occur quizlet?
what is apoptosis? it is a form of programmed cell death. -this occurs when a cell senses signals that trigger a clean cell death. -it is programmed because the genome has many genes involved in sensing the reason for initiation of death, how to die and removal of apoptotic bodies. -it leads to autoimmunity.
What is the mechanism of apoptosis?
apoptosis, also called programmed cell death, 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.
What is apoptosis pathology?
APOPTOSIS. Programmed cell death in which there is death of individual cells without inciting inflmmatory processes. In embryogenesis and normal growth, physiologic cell death occurs which may be referred as programmed cell death or apoptosis. Apoptosis can also occur in pathologic diseases.
