Lone Rock Beach and Horseshoe Bend in Page, Arizona. After we left Holbrook, we headed over towards Flagstaff, Arizona to stock up on some supplies and do some housekeeping.
Glycolysis involves nine distinct reactions that convert glucose into pyruvate. In this section, we will cover the first four of these reactions, which convert glucose into glyceraldehyde-3-phosphate.
1 Glucose-1-phosphate is converted into UDP-glucose by the action of the enzyme UDP-glucose phosphorylase. 2  Pyrophosphate is formed, which is later hydrolysed by pyrophosphatase into two phosphate molecules. Glucose is converted into glucose-6-phosphate by the action of glucokinase or hexokinase.
