PASSIVE TRANSPORT Requires no energy input from the cell Goes WITH the concentration gradient Usually small, uncharged particles ACTIVE TRANSPORT -requires energy input from the cell -goes against the concentration gradient -large particles or charged particles Types of Passive Transport Simple Diffusion ...
Active transport requires energy and is linked to energy available from ion gradients or ATP hydrolysis. • Group translocation: phosphotransferase system (PTS). Group translocation is the process whereby a substance is transported while simultaneously being chemically modified, generally by phosphorylation...

Active and passive transport are the ways in which cells allow things to move into and out of the cell through the cell membrane. They include many different ways to transport things. Passive transport requires no expenditure of energy by the cell. However, Active transport requires ATPs which...
Active Transport Requires energy Is the movement of molecules across a membrane Usually moves from a low concentration to a high concentration Plants use active transport to remove nutrients from the soil Examples: Plants use active transport to remove nutrients from the soil Animals use active transp...
the materials.Unfortunately this kind of transport requires the cell to work against the natural direction of diffusion so the cell uses up energy. 5 They pump sodium out of their cells and pull potassium in.Although they must use energy in this process doing so allows them to thrive (成长)...
Since their movement is downhill or along their concentration gradient, the process does not require metabolic energy (e.g. ATP) as opposed to active transport, another type of cellular transport that essentially requires ATP to move substances against their concentration gradient. The four major ...
The meaning of PASSIVE TRANSPORT is the movement of substances (as by diffusion) across a cell membrane without the expenditure of energy.
Active:An Active transport requires the cell to expend energy in the form of ATP to move substances against their concentration gradient. This process is crucial for maintaining proper ion balances and nutrient uptake. Passive:A Passive transport occurs spontaneously, driven by the natural movement of...
