By knowing the details on where and what about the organism, this helps with a lot of crime such as murder.
In many cases, the activity of an enzyme is regulated by Negative feedback where the end product acts as a non competitive inhibitor.
In feedback inhibition the end product of a metabolic pathway acts on the key enzyme regulating entry to that pathway, keeping more of the end product from being produced. The feedback inhibition acts at the first committed step of the pathway, meaning the first step that's effectively irreversible. The pathway steps regulated by feedback inhibition are often catalyzed by allosteric enzymes.
Because viruses have the ability to infect cells. E.G a dendritic cell. So the only thing that can kill then are natural killer cells but then viruses reproduct in these cells
