co-transport and absorption of glucose in the ileum

Question 1

Microvilli

Answer 1

Provides more SA for insertion of carrier proteins

Question 2

sodium potassium pump

Answer 2

1) na ions transported out of epithilial cells into the blood. takes place in protein carrier molecules
2) maintains high conc of na ions in lumen of intestine
3) na ions diffuse into epithelial cells. as they go through carrier proteins they bring through amino acids or glucose molecules
4) amino acids pass into the blood plasma through facilitated diffusion using another type of carrier protein
