The Glycolytic Pathway Is Tightly Controlled Biochemistry .

The flux through the glycolytic pathway must be adjusted in response to conditions both inside and outside the cell. The rate of conversion of glucose into pyruvate is regulated to meet two major cellular needs: 1 the production of ATP, generated by the degradation of glucose, and 2 the provision of building blocks for synthetic reactions, such as the formation of fatty acids.

Glycolysis California State University, Northridge

Glycolysis is a universal pathway present in all organisms: from yeast to mammals. In eukaryotes, glycolysis takes place in the cytosol Glycolysis is anaerobic it does not require oxygen In the presence of O2, pyruvate is further oxidized to CO2. In the absence of O2, pyruvate can be fermented to lactate or ethanol.

They depend on glycolysis and lactic acid production for rapid ATP production. Aerobic Respiration. In the presence of oxygen, pyruvate can enter the Krebs cycle where additional energy is extracted as electrons are transferred from the pyruvate to the receptors NAD , GDP, and FAD, with carbon dioxide being a waste product Figure 24.2.3 .

MCQ: Glycolysis, Gluconeogenesis, Pentose Phosphate Pathways .

A Aerobically, oxidative decarboxylation of pyruvate forms acetate that enters the citric acid cycle. B In anaerobic muscle, pyruvate is converted to lactate. C In yeast growing anaerobically, pyruvate is converted to ethanol. D Reduction of pyruvate to lactate regenerates a cofactor essential for glycolysis.

Glycolysis Regulation

Glycolysis Regulation. It is a general rule of metabolic regulation that pathways are regulated at the first committed step. The committed step is the one after which the substrate has only one way to go. Because glycolytic intermediates feed into several other pathways, the regulation of glycolysis occurs at more than one point.
