Question

Example of destruction of organization of a cell physically

Answer 1

Answer:

ExpNecrosis is characterised by cytoplasmic swelling, irreversible damage to the plasma membrane, and organelle breakdown leading to cell death. The stages of cellular necrosis include pyknosis; clumping of chromosomes and shrinking of the nucleus of the cell, karyorrhexis; fragmentation of the nucleus and break up of the chromatin into unstructured granules, and karyolysis; dissolution of the cell nucleus.Cytosolic components that leak through the damaged plasma membrane into the extracellular space can incur an inflammatory response.

There are six types of necrosis

Coagulative necrosis

Liquefactive necrosis

Caseous necrosis

Fat necrosis

Fibroid necrosis

Gangrenous necrosis

Apoptosis

Apoptosis is the programmed cell death of superfluous or potentially harmful cells in the body. It is an energy dependent process mediated by proteolytic enzymes called caspases, which trigger cell death through the cleaving of specific proteins in the cytoplasm and nucleus.The dying cells shrink and condense into apoptotic bodies. The cell surface is altered so as to display properties which lead to rapid phagocytosis by macrophages or neighbouring cells. Unlike necrotic cell death, neighbouring cells are not damaged by apoptosis as cytosolic products are safely isolated by membranes prior to undergoing phagocytosis. In the average adult between 50 and 70 billion cells die each day due to apoptosis. Inhibition of apoptosis can result in a number of cancers, autoimmune diseases, inflammatory diseases, and viral infections. Hyperactive apoptosis can lead to neurodegenerative diseases, hematologic diseases, and tissue damage.lanation:
