Absorption

This is a legacy topic. View the most up to date content by selecting the exam board in the dropdown to the left.

 

When carbohydrates from food are digested, lots of glucose molecules, along with some fructose and galactose, are produced in the small intestine. Initially the mode of transport of glucose in absorption is diffusion. It is then followed by facilitated diffusion via co-transport, where glucose molecules are absorbed along with a sodium ion (Na+) through a carrier protein. This method is much faster than diffusion by itself.

 

Both Na+ and glucose must be present for absorption by co-transport to take place.

 

That’s it, be glad this is a small topic ?

I’ve struggled so much with feeling overwhelmed with biology revision, and I don’t know where to start. But your website is just what I need! It tells me all the information I need, and the knowledge I need to then build on, and it’s written in a way that soaks straight up into my brain!
