An example of active transport occurs in human nerve cells. Here, sodium ions are constantly transported out of the cell into the external fluid bathing the cell, a region of high concentration of sodium. (This transport of sodium sets up the nerve cell for the impulse that will occur within it later.)
What else can I help you with?
Is coupled transport an example of active or passive transport?
Coupled transport is an example of active transport.
The transport of materials against the concentration gradient is called?
In biology (and cut potatoes in baths) this process is called Osmosis; in the Water Purification Industry the process called Reverse Osmosis is employed.
Is exocytosis a form of active transport or passive transport?
Exocytosis is a form of active transport.
How do faciliated diffusion and active transport differ?
In active transport, the molecules are carried against the force of diffusion. This is the opposite of facilitated transport. Also in active transport, energy in the form of ATP is required, since the molecules move against the normal flow. Note that energy is not needed in facilitated transport.

What are 2 types of active transport?
A) Active transport through special transport proteins in the plasma membrane. ATP causes these proteins to change shapes and move materials from low to high concentration. B) Bulk transport - moving large particles through the membrane by endocytosis or exocytosis.
Is coupled transport an example of active or passive transport?
Coupled transport is an example of active transport.
Is endocytois an example of active or passive transport?
Endocytosis is an example of active transport.
Where can one find information about active transport in biology?
There are several ways to find out about active transport in terms of biology. One can inquire with a biology professor at a school or a college, research the subject using biology textbooks or library books, or research the subject on biology related websites, such as Biology4Kids.
Is pinocytosis acitve or passive transport?
It is the active transport of liquids in vesicles into and out of a cell so it uses metabolic energy, thus active
What is an example of a situation that depends on active transport?
When food moves across a cell membrane, it requires Active Transport.
What is an example is active transport?
An example of active transport is sugar molecules going into a cell. It cannot pass right through like water and oxygen so it uses active transport.Diffusion

Lactose uptake in E coli is an example of which type of transport?
it's an example of secondary active transport.
An example of active transport?
sodium-potassium pump
Sodium potassium pump is an example of what?
Active transport
Is diffusion an example of active transport or passive transport?
Diffusion is an example of passive transport, like osmosis(the diffusion of water through a membrane).
Lactose uptake in E. coli is an example of which type of transport?
secondary active transport
