Absorption of glucose

The SODIUM POTASSIUM PUMP allows for sodium ions to be actively transported out of the cell , atp is required as it is against the concentration gradient . this lowers the sodium ion concentration inside the epithelial cell creating a conc gradient. 2. The glucose and sodium ions from the lumen bind to NA+/GLIUCOSE CO TRANSPORT PROTEINas they are facilitated diffused into the cell from (high-low ) 3. GLUCOSE CHANNEL PROTEIN allows glucose to be absorbed from the ep cell into the blood by facilitated diffusion
