We have already discussed how competitive inhibitors can affect the enzyme activity. Toxicology and Enzyme Inhibition Toxicolgy is the study of toxic agents. Toxic agents is a little disceptive. Most people think of something that is toxic as something that will cause certain death. This is not always the case.
Toxicity depends on a number of factors.
The body weight of the organism has to be considered. The tolerance level of the toxin in the organism is a factor. The dosage of toxin ingested and the time interval of the ingestion all have to be considered as important to gauge just how toxic a toxin is. To use a ridiculous hyperbole, one can die of too much water due to kidney shutdown, but we would not think of calling water a toxin. Depending on the dosage and body weight some toxins only nausiate whereas others cause vomiting, convulsions, coma, and, yes, even death.
