Evidence suggests that alcohol affects brain function by interacting with multiple neurotransmitter systems, thereby disrupting the delicate balance between inhibitory and excitatory neurotransmitters. Short-term alcohol exposure tilts this balance in favor of inhibitory influences. After long-term alcohol exposure, however, the brain attempts.

Ethyl alcohol kills bacteria mainly through 2 mechanisms: protein denaturation and dissolving the lipid membrane.
