WebAlcohol fermentation has two steps: glycolysis and NADH regeneration. During glycolysis, one glucose molecule is converted to two pyruvate molecules, producing two net ATP and two NADH. During NADH regeneration, the two pyruvate molecules are first converted to two acetaldehyde molecules, releasing two carbon dioxide molecules in the process. WebThe processes of making and breaking down glucose molecules are both examples of metabolic pathways. A metabolic pathway is a series of connected chemical reactions that feed one another. The pathway takes in one or more starting molecules and, through a series of intermediates, converts them into products.

WebJan 25, 2024 · Glycolysis is an anaerobic oxidative process because it occurs in the absence of free oxygen, and there is a loss of hydrogen. In this process, one molecule of glucose is broken down into two molecules of pyruvic acid. In this process, two molecules of ATP are used to produce four molecules of ATP.
