WebMovement Across a Membrane and Energy. There are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used. Passive mechanisms like diffusion use no energy, while active transport requires energy to get done. WebPassive Transport: Osmosis Osmosis is the diffusion of water through a semipermeable membrane according to the concentration gradient of water across the membrane. Whereas diffusion transports material across …
WebMar 26, 2016 · The diffusion rate depends on the mass and temperature of the molecule; lighter and warmer molecules move faster. 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 ... WebIn facilitated diffusion, passive transport allows certain substances to cross membranes with the help of special proteins that are there to help transport these substances. Substances such as sodium ions, glucose, …

During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.
