The major difference between active and passive transport is that passive transport does not require the application of external energy, while active transport does. Both processes move molecules across the cell membrane... More »

Primary and secondary active transport refer to the movement of molecules and cell components within cells and throughout the body. Primary and secondary active transport require energy to work and are both important for... More »

Active transport is important for cellular function because it moves important items, such as calcium and glucose, into and out of cells. Proteins sit on the cell membrane, with one part inside and one part outside the m... More »

Some examples of active transport are endocytosis, exocytosis and the use of a cell membrane pump; diffusion, osmosis and facilitated diffusion are all examples of passive transport. In active transport, particles move f... More »

The simplest type of passive transport is diffusion or simple diffusion. Osmosis, which is also a form of passive transport, is similar to diffusion in that both move a substance from an area of high concentration to an ... More »

Osmosis is an example of passive transport. Osmosis is the diffusion of water across a membrane from an area of high concentration to an area of low concentration. More » Science Biology Cells

There are four different types of passive transport: diffusion, facilitated diffusion, filtration and osmosis. Diffusion is the movement of substances from an area of high concentration to an area with lower concentratio... More »
