Active and passive transport are systems that are meant for transporting molecules through the cell membrane. A cell membrane is a multi-task component

Active transport is the movement of molecules or ions against a concentration gradient (from an area of lower to higher concentration), which does not ordinarily occur, so enzymes and energy are required. Passive transport is the movement of molecules or ions from an area of higher to lower concentration.

Facilitated diffusion and active transport are two methods involved in the transportation of molecules across the cell membrane. The plasma membrane of a cell is selectively permeable to the molecules which move across it. The difference between passive transport and active transport is that the active transport requires energy, and moves substances against their respective Passive transport is a type of membrane transport that does not require energy to move substances across cell membranes. Instead of using cellular energy, like 9 Nov 2010 Examples of passive transport include passive diffusion, ion channels, and facilitated diffusion. Active transport is the movement of solutes across Passive transport is the movement of substances across the membrane without the expenditure of cellular energy.

Active transport vs passive transport 1. active transport vs passive transport:The human body is a complicated network of cells and molecules and the interactionbetween these cells and the different fragments can be quite fascinating.

Aktiv transport och passiv transport är två sätt för molekylära rörelser. Active transport requires chemical energy because it is the movement of biochemicals from areas of lower concentration to areas of higher concentration. On the other hand, passive transport moves biochemicals from areas of high concentration to areas of low concentration; so it does not require energy.
