Kristin has taught college Biology courses and has her doctorate in Biology. Definition and Significance of Active Transport Active transport is the movement of ions or molecules against their concentration gradient, which involves the input of chemical energy. This transport is carried out by integral...
Active Transport vs. Passive Transport Passive transport is another form of cellular transport. It is one of the mechanisms employed by a cell to move substances across a biological membrane. It differs from active transport in the way that the substances move not against but along the direction...
In biology, transport refers to the act or the means by which a molecule or ion is moved across the cell membrane or via the bloodstream. There are two types of transport in this regard: (1) passive transport and (2) active transport. Passive transport is a kind of transport by which ...
Active Transport is the movement of molecules from a region of lower concentration to a region of higher concentration with the use of energy.

Active transportis the process of moving particles from an area of lower concentration to an area of higher concentration. In other words, it is a backwards flow as compared to that of diffusion and requires an input of energy into the system to accomplish the movement. Therefore, diffusion is...

Kristin has taught college Biology courses and has her doctorate in Biology. In this lesson, we've learned several different methods of passive transport, or transport across the cell membrane that does not require energy. Passive transport moves across a concentration gradient, or a gradual differe...
What is exocytosis in biology? Exocytosis is a process that occurs when a cell moves large materials from inside the cell to the outside of the cell using small spheres of membrane called vesicles. This process is a form of active transport, meaning it uses energy. During exocytosis, vesicles...
