Question
Upon necrosis, contents of cell are released into extracellular environment. ____
Answer
Upon necrosis, contents of cell are released into extracellular environment. True.
Note: Because the blebs are contained by a membrane, this also prevents the release of potentially harmful substances into the extracellular environment. This is different from necrosis, which is a process of cell death in which a cell dies as a result of injury. In necrosis, internal substances can be leaked, causing irritation of nearby tissues or even an immune response.
Note: For example, the fingers are originally webbed during development of the hand. The cells of the webbing later undergo apoptosis, resulting in separation of each individual finger and toe.
