Question

What products of glycolysis are required for yeast to produce ethanol by fermentation?

Answer 1

NADH, pyruvate.

Step-by-step explanation:

The fermentation process occurs in the cytoplasmic matrix.

Thanks to the H+ that are recovered from the oxidation of NADH to NAD +, they bind to pyruvic acid to change its conformation and transform it into lactic acid.

Two types of fermentation occur:

- Lactic

- Alcoholic, which releases ethanol + CO2

This is the reaction:

C6H12O6 + 2 Pi + 2 ADP + 2 NAD → 2 CH3-CH2OH + 2 CO2 + 2 ATP + 2 NAD
