And so only these green molecules will become trapped because they're bound onto the glucose of the bees. And the other two enzymes, enzyme two and three, will not interact with the glucose in any way. So they will simply continue traveling along and down our column. So when we pour the crude mixture proteins, the protein with affinity for glucose will bind to the beads. For example, that protein could be glucose oxidase that we spoke about earlier, or it could be some other protein that also binds to glucose. So the other molecules, however, these proteins here did not bind to the glucose on the beads, and so they continue traveling to the bottom of that column.
