WebSep 15, 2024 · Passive transport is a way that small molecules or ions move across the cell membrane without input of energy by the cell. The three main kinds of passive transport are diffusion (or simple diffusion), osmosis, and facilitated diffusion. Simple diffusion and osmosis do not involve transport proteins. WebAll substances that move through the membrane do so by one of two general methods, which are categorized based on whether or not energy is required. Passive and Active Passage Through the Cell Membrane Passive transport is the movement of substances across the membrane without the expenditure of cellular energy. devops team lead salary
