Fermentation question

Hi everyone!

Quick question. So I went over some cell respiration questions, and some of them involved having answers along the lines of "fermentation creates atp". Just to clarify, is fermentation the entire reaction of glucose to lactate or ethanol/co2, or is it just pyruvate to lactate/ ethanol+co2? Because I thought it was the reaction from pyruvate, which wouldn't directly produce atp.

Thanks in advance!

The overall process of fermentation includes glycolysis + the additional process that regenerates NAD+.

Fermentation is a process that is important in anaerobic conditions when there is no oxidative phosphorylation to maintain the production of ATP (Adenosine triphosphate) by glycolysis. During fermentation pyruvate is metabolized to various different compounds. Homolactic fermentation is the production of lactic acid from pyruvate; alcoholic fermentation is the conversion of pyruvate into ethanol and carbon dioxide; and heterolactic fermentation is the production of lactic acid as well as other acids and alcohols.

Hope this helps
