In this video, we look at cotransport. I explain to you how cotransport works, using the example of the ileum where glucose is absorbed by cotransport. I then explain how the ileum epithelial cells are adapted for rapid absorption of glucose.

This video is aimed at the UK A Level Biology specifications. Students studying International A Level Biology will need to check their specification.
