Ethanol will generate 1. through the action of alcohol dehydrogenase, and this will 2. formaldehyde back to 3., also through alcohol dehydrogenase. The 4. formed can be metabolized further to acetate. Ethanol may also compete with methanol for binding to alcohol dehydrogenase.

Explanation:

Alcohol dehydrogenase(ADH) is a cystolic enzyme which is mainly found in liver,catalyze the break down of alcohol to aldehyde. This binding of alcohol to alcohol dehydrogenase releases electrons which is accepted by NAD+ to form NADH. The aldehyde that is formed is further oxidized to an acid by alcohol dehydrogenase 2.

Oxidation of ethanol by alcohol dehydrogenase will produce acetaldehyde, and NAD+ will be reduced to NADH in the process. This acetaldehyde is a toxic compound so it will be further oxidized to acetate by alcohol dehydrogenase 2 enzyme.

Formaldehyde can be reduced back to methanol in the presence of NADH by alcohol dehydrogenase.
