So that's an H plus ion and two electrons from the glucose and onto the NAD plus carrier molecule. So this is the electron acceptor that picks up two electrons and that H plus ion. And we also release a hydrogen ion. So we form this intramolecular ester molecule known as six phosphorluquino delta lactone. Now let's move on to step two. So in step two, what we want to basically do is we want to prepare the molecule for a decorboxylation reaction.
