And what we form is the two NADPH molecules and one ribose phi phosphate molecule. In addition, we also produce a carbon dioxide and two H plus ions. So basically this is what the cell will carry out and then it will use these molecules to help carry out other processes that we discussed just a moment ago. Now let's move on to case two. Now in case number two, we're assuming that our cell actually needs the ribose phyphosate molecule much more than it needs the NADPH molecule. Now what's an example of a cell that will experience this particular case?
