WebJan 19, 2024 · What Is Passive Transport? Of the two types of movement across cellular membranes, passive transport is certainly the easier option. Utilizing the process of diffusion, which describes the movement of molecules from a region of higher concentration to lower concentration, passive transport requires no energetic input from the cell—no … WebBoth active and passive transport move substances down their concentration gradients. Active transport is ATP dependent. Passive transport does not require energy. Active …
WebTransport across a cell membrane is a tightly regulated process, because cell function is highly dependent on maintain strict concentrations of various molecules.
