Now let's move on to hexokinase and let's recall the first three processes in glycolysis. So in step one we have glucose transformed into glucosex phosphate by hexokinase. This is also an irreversible process. We have a reversible process that is catalyzed by phosphlucose isomerase. We transform glucose six phosphate into its isomer fructosex phosphate and then this third step takes place in which we transform the fructosex phosphate into this committed molecule fructose one six bisphosphate by phosphorptokinase. So let's suppose we're at rest and what that means is we're going to have high energy charge value.
