What happens is an enzyme known as hexokinase. HEXO means we have 123456 carbons in our sugar kinase, means we're going to phosphorylate that glucose. So a phosphoryl group is taken from the ATP by the hexokinase and is added onto carbon number six. And so we form glucose phosphate. We break down the ATP into ATP and also the H ion is released as well. And this reaction releases this amount of energy.
