So we have the fructose one six bisphosphate. So carbon number one contains the phosphate group as well as carbon number six. And this is our fructose molecule. Now, in the presence of water, which we have plenty in a cytoplasm, remember, all these steps basically take place in a cytoplasm except step number one and step number ten. And so the water is used to hydrolyze this ester bond via the activity of fructose one six bisphosphatase. And remember, it's a phosphatase, because phosphatases take off phosphoryl groups while kinase is actually put on those phosphoryl groups.
