Question

× Y Connect 86c02-40925xM Access Connect tion.com/flow/connect.html stive System quiz Which of the following statements is true regarding the sodium-glucose transport protein (SGLT)? Multiple Choice It is a uniport carrier It is an antiport carrier. It uses solvent drag to transport glucose and sodium. transports glucose and sodium from the intestinal lurmen into the epithelial cells. It transports glucose from the intestinal lumen into the epithelial ceills, and sodium in the opposite direction.

Explanation / Answer

A common example of secondary active transport is the symport of sodium and glucose. The transmembrane protein Na+-glucose transporter, acts as a carrier, allows Na+ and glucose to enter the cell together. The Na + flow down their concentration gradient while the glucose molecules are transported against their concentration gradient into the cell.

Therefore option D

It transports glucose and sodium from intestinal lumen into epithelial cells.
