WebPrimary and secondary active transport proteins differ in that primary active transport proteins __________________. move both molecules against their gradients, while secondary active transport proteins couple the movement of an ion down its gradient with the movement of another molecule against its gradient Webother forms than ATP. During secondary active transport, molecules are transported due to an electrochemical gradient generated by moving another molecule across the membrane along with the molecule of interest. Symport and antiport are two types of proteins involved in secondary active transport. The key Web26 mrt. 2016 · Diffusion is one form of passive transport that doesn’t require the expenditure of cellular energy. A molecule can diffuse passively through the cell membrane if it’s lipid-soluble, uncharged, and very small, or if a carrier molecule can assist it. The unassisted diffusion of very small or lipid-soluble particles is called simple diffusion. list of free photo editing software
