Which enzyme converts glucose to ethanol?

Zymase

The answer is (c) zymase.

Zymase is an enzyme complex that is produced by yeast and other microorganisms. It is responsible for the fermentation of sugars, which is the process of converting sugars into ethanol and carbon dioxide.

Invertase is an enzyme that is responsible for the hydrolysis of sucrose, a disaccharide, into glucose and fructose. However, it does not convert glucose to ethanol.

Diesterase is an enzyme that is responsible for the hydrolysis of esters, which are compounds that are formed from an alcohol and an acid. It does not convert glucose to ethanol.
