NAD

Slide 26

This means that respiration cannot proceed beyond the first stage – glycolysis.

The 2C intermediate accepts the hydrogen atoms from NADH/H+ and forms ethanol

NAD

Slide 27

This means that respiration cannot proceed beyond the first stage – glycolysis.

A considerable amount of energy is trapped in the ethanol
