Answer:
Toxic damage to cells can cause individual cell death and if sufficient cells are lost, the result can be tissue or organ failure, ultimately leading to death of the organism. It is nearly impossible to separate a discussion of cellular toxicity and biochemical toxicity. Most observable cellular changes and cell death are due to specific biochemical changes within the cell or in the surrounding tissue. However, there are a few situations where a toxic chemical or physical agent can cause cell damage without actually affecting a specific chemical in the cell or its membrane. Physical agents such as heat and radiation may damage a cell by coagulating their contents (similar to cooking). In this case, there are no specific chemical interactions. Impaired nutrient supply (such as glucose and oxygen) may deprive the cell of essential materials needed for survival.
