WebbIn active transport, unlike passive transport, the cell expends energy (for example, in the form of ATP) to move a substance against its concentration gradient. Here, we’ll look in more detail at gradients of molecules that exist across cell membranes, how they can help or hinder transport, and how active transport mechanisms allow molecules to move … WebbBoth simple and facilitated diffusion mechanisms are types of passive transport where solute molecules move from a region of higher to a region of lower concentration. The difference between them is that in simple …
