how stuff is adsorbed into enterocytes?

[orangeblossom]

is this correct?
For carbohydrates, glucose is absorbed into enterocytes via active transport. Fructose is via facilitated diffusion

For amino acids & fats, its facilitated diffusion.

On a related note, glucose absorption in body is always facilitated diffusion EXCEPT in 2 places: enterocytes and renal tubules?

Any other bits of information anyone would like to share?

Glucose into entrocyctes, Na+ is pumped out on the basolateral side and so Na+ conc in the cell is low, and so Na+ actively pumped into the cell from the lumen side and only if glucose is attached to a carrier protein will it enter the entrocycte. So basically it needs carrier protein

I prob spelled a lot of words wrong...

Just for the record, adsorb and absorb mean different things.

Not if you've a cold! A haahahahaha

Seriously, that was my first thought. Godric has it right, glucose is absorbed via sodium cotransport. Fructose is not, which is why it's slightly less efficiently absorbed. Iirc 95% vs almost 100% but don't quote me on those numbers.
