Alcohol is a drug.

Atoms are composed of Electrons, protons and Neutrons. Protons and Neutrons together called as Nuclei.

The minimum amount of energy required for a particular reactants to convert into products and is called as Activation Energy.

This activation complex is also termed as Transition State because according to Transition State Theory at transition state the existing bonds tend to increase in length and become weaken while, the new forming bonds tend to decrease in length and start becoming stronger.

Hence, the activated complex is in transition between reactants and products.
