The binding of the transported molecule to the carrier protein induces a conformational change, allowing the molecule to be shuttled across the membrane. They are distinguished according to the directionality of the two molecules: Uniport and symport are two types of transport mechanisms used by cells to move substances across their membranes. This process is essential for maintaining cellular homeostasis and often involves the co-transport of a nutrient or ion along with sodium or another driving ion, allowing for efficient uptake or expulsion of substances from Uniport only allows for the movement of one type of molecule, whereas symport and antiport allow for the movement of two different types of molecules. D. Symport is the process in which the molecules move along, in the same direction.
