WebSep 21, 2024 · In the first reaction, a carboxyl group is removed from pyruvic acid, releasing carbon dioxide as a gas. The loss of carbon dioxide reduces the molecule by one carbon atom, making acetaldehyde. The second reaction removes an electron from NADH, forming NAD + and producing ethanol from the acetaldehyde, which accepts the electron. WebWhen active (live) yeast has both sugar and oxygen available to it, it ’breathes’ by a process called aerobic respiration. In this reaction, yeast cells use glucose (sugar) and oxygen …
