Three common types of passive transport include simple diffusion, osmosis, and facilitated diffusion.

Examples of active transport include the transportation of sodium out of the cell and potassium into the cell by the sodium-potassium pump. Active transport often takes place in the internal lining of the small intestine.

Endocytosis. Endocytosis is a type of active transport that moves particles, such as large molecules, parts of cells, and even whole cells, into a cell.

In primary active transport, the energy is derived directly from the breakdown of ATP. In the secondary active transport, the energy is derived secondarily from energy that has been stored in the form of ionic concentration differences between the two sides of a membrane.

ATP is an energy molecule, and when hydrolysis happens, it gets broken down to release the energy that was stored in its chemical bonds. Transport that directly uses ATP for energy is considered primary active transport.

Types of passive transport include simple diffusion, osmosis, and facilitated diffusion. Active transport requires energy from the cell. It occurs when substances move from areas of lower to higher concentration or when very large molecules are transported.

Therefore; an essential part of transportation management lies in building an efficient supply chain from the six main modes of transportation: road, maritime, air, rail, intermodal, and pipeline. Understanding the strengths and weaknesses of each mode is paramount to building an effective supply chain.

During active transport, a protein pump uses energy, in the form of ATP, to move molecules from an area of low concentration to an area of high concentration. An example of active transport is the sodium-potassium pump, which moves sodium ions to the outside of the cell and potassium ions to the inside of the cell.
