Concept:

Alcoholic fermentation is a biochemical process in which sugars such as glucose, fructose, and sucrose are converted into cellular energy, producing ethanol and carbon dioxide as metabolic waste.

Formula:

$$ \text{C}_6\text{H}_{12}\text{O}_6 \xrightarrow{\text{Zymase}} 2\text{C}_2\text{H}_5\text{OH} + 2\text{CO}_2 $$

Solution:

• Yeast naturally contains an enzyme complex called zymase.
• Zymase catalyzes the fermentation of simple sugars like glucose into ethanol and carbon dioxide.

Why other options are incorrect:

Invertase catalyzes the hydrolysis of sucrose into fructose and glucose. Urease catalyzes the hydrolysis of urea into carbon dioxide and ammonia. Sucrase is similar to invertase in breaking down sucrose.
