Vedclass · Answer

(D) In secondary active transport,such as the symport of sugars or amino acids across the cell membrane,the transport protein utilizes the electrochemical gradient of $Na^+$ ions.Specifically,$Na^+$ ions move into the cell down their concentration gradient (from a region of higher concentration outside to a region of lower concentration inside).This movement of $Na^+$ ions provides the energy required to transport sugar or amino acid molecules against their own concentration gradient into the cell.Therefore,$Na^+$ ions move in the direction of their concentration gradient.

During the transport of sugar or amino acids through the cell membrane,what is the movement of $Na^+$ ions?
