Question 4 of 5
What is the name given to the movement of glucose or amino acids from the gut into the cells lining the gut, when they bind to a transport protein that has also bound a sodium ion. The sodium ion is entering the cell along its concentration gradient.
Correct Answer: D
Rationale: The sodium ion was transported out of the cell with the use of energy in order to set up the sodium concentration gradient. This gradient then allows other molecules to enter the cell along with sodium's re-entry. This is active(because energy used), but secondary as it occurs as a result of the previous active transport event.
