There are many points during the cell cycle when the process of division may stop because of a problem. Sometimes the process doesn’t stop. Summarize the function of apoptosis in the cell cycle
A.to repair damaged or old cells
B. Todestroy damaged or old cells
C. To facilitate cell reproduction before the cell cycle restarts
D. To allow the cell to rest before the cell cycle starts
B. To destroy damaged or old cells
The function of apoptosis in the cell cycle is to destroy damaged or old cells. This process is crucial for maintaining the overall health and functionality of multicellular organisms. When a cell undergoes apoptosis, it undergoes a controlled process of self-destruction. This is typically triggered when a cell detects DNA damage, severe cell stress, or when it becomes old and no longer functional.
Apoptosis involves a series of biochemical events that lead to the dismantling and disposal of the cell. It starts with the activation of specific genes, which lead to the production of proteins that initiate the destruction of the cell. The cell's nucleus undergoes changes, including condensation of chromatin and fragmentation of DNA. The cell's membrane also changes, leading to the formation of blebs or bulges on its surface.
By undergoing apoptosis, the damaged or old cell is effectively removed from the organism. This prevents the propagation of potentially harmful mutations or malfunctioning cells. Additionally, apoptosis plays a crucial role during development by eliminating cells that are no longer needed or are in excess. This helps shape and refine different organs and tissues.
In summary, the main function of apoptosis in the cell cycle is B. to destroy damaged or old cells in order to maintain the overall health and functionality of an organism.
B. To destroy damaged or old cells.
Apoptosis, also known as programmed cell death, is a crucial process in the cell cycle that regulates cell growth and eliminates cells that are damaged, dysfunctional, or no longer needed. Its main function is to destroy these cells by triggering a series of biochemical events that lead to their self-destruction. This helps maintain the overall health and proper functioning of tissues and organs by getting rid of unwanted or abnormal cells.
