Let's imagine this is a cytoplasm of our cell. So we have the glucose six phosphate. What happens next is we use a special type of membrane protein found on the membrane of the endoplasm reticulum. So this is the membrane of the er, and this is the lumen of the Er. And so what happens is by using a special membrane protein known as T one, or glucose six phosphate transporter, the glucose six phosphate enters the lumen of the Er. And once inside the lumen of the Er, the glucosex phosphate in the presence of water, because, again, we have plenty of water in the lumen of the Er, it's transformed into glucose and a single inorganic phosphate.
