Final answer:
Three key organic reactions in this process are phosphorylation of glucose, isomerization of glucose-6-phosphate, and oxidation and phosphorylation of glyceraldehyde-3-phosphate.
Step-by-step explanation:
Understanding Glycolysis and Its Key Organic Reactions: Identify glycolysis: Glycolysis is a central metabolic pathway that converts glucose into pyruvate, producing ATP and NADH in the process. It is not oxygen-dependent and occurs in the cytoplasm of cells. During glycolysis, a glucose molecule undergoes a series of transformations and ends up as two three-carbon pyruvate molecules. This process can be broken down into three stages: investment, cleavage, and energy harvest. In the absence of oxygen, pyruvate can undergo fermentation, whereas in the presence of oxygen, it can enter the Krebs cycle for further energy extraction.Three organic reactions involved in glycolysis include:Phosphorylation of glucose to form glucose-6-phosphate.
This reaction involves the functional group transfer as a phosphate group is transferred from ATP to glucose.Isomerization of glucose-6-phosphate to fructose-6-phosphate, which involves the rearrangement of atoms within the molecule.Oxidation and phosphorylation of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate, which results in the production of NADH and includes the process of adding a phosphate group as well as an oxidation event.These reactions feature various functional groups, including alcohols, aldehydes, ketones, and carboxylic acids, which are integral to the conversion of glucose into energy currency for the cell.
