Transport across membranes. Co-transport brings together active transport and facilitated transport to ensure Glucose is absorbed full from the ilium.

post note - the protein that allows transport of glucose out of the cell into the blood is a carrier protein and not a protein channel as I mention in the video. The basic principles are the same but protein channels are mainly for ions and carrier proteins for molecules such as glucose. However,
it is important to note that, when referring to protein
carriers/channels, only carriers can be used for active transport; either can be involved in
