Why does zymac kill?

Zymac, a fictional or hypothetical substance, may be described as lethal due to its toxic properties, which can lead to severe physiological reactions in living organisms. Its mechanism of action might involve disrupting essential biological processes, such as inhibiting cellular respiration or interfering with neurotransmitter functions. Additionally, zymac may trigger an immune response that results in systemic failure. Without specific context, it's essential to clarify that the effects of zymac are not based on real science but rather on fictional narratives.
