1. in intestinal epithelial cells, a transport protein moves the bulky, polar glucose molecules through the membrane into the cytoplasm, while simultaneously transporting na+ through the membrane into the cell down its electrochemical gradient. which example correctly describes this cotransport of glucose and sodium? secondary active transport by an antiporter primary active transport by an antiporter secondary active transport by a symporter primary active transport by a symporter

Secondary active transport by a symporter.

Explanation:

bc others are wrong

Secondary active transport by a symporter

Explanation:

In secondary active transport, the electrochemical potential difference is created by pumping ions in or out of the cell. There is no coupling of ATP. The downhill movement of one solute from high to low concentration to move another molecule along with it is called symport. Symport is one of the form of secondary active transport. The example of symport is the co-transports one glucose molecule into the cell for every two sodium ions it imports into the cell. This symporter is located in the small intestine epithelial cells, trachea, heart, brain, testis.
