Active transport is when the cell moves particles from an area of low concentration on one side of the cell membrane, to an area of high conc. on the other side, by means of a protein embedded in the membrane.

It requires the input of energy (in the form of ATP) to move particles against the concentration gradient.

How is facilitated diffusion diferant froma an active transport?
Facilitated diffusion is a type of passive transport which does not require the cell to expend energy.
What is the general term for cell transport that doesn't require energy?
This type of transport is generally called passive transport.
What is the different between active transport and passive transport of molecules across the cell membrane?
In an active transport, the cell uses energy (ATP) to transport the particle into the cell. Also, the particle moves through a "hallway" type thing. In a passive transport, the cell does not need energy (ATP) to transport the particle into the cell. Also, the particle just bursts through the cell membrane to get inside.
What type of carrier proteins use energy and act as a pump to move nutrients into a root cell?

What are passive transport active transport and endocytosis?
These are three different ways that cells have to get things in and out of the cell. Passive transport is movement without the use of energy, active transport requires energy.Active transport requires energy since the molecules are going toward a region that has a higher concentration of that molecule. The cell is 'stuffing' more into itself.Endocytosis means to 'take into the cell'. Usually this a larger molecule and cell must wrap part of itself around the molecule and then can bring it inside. This is a type of phagocytosis (cell eating).This requires energy as well.

A cell must expend energy to transport substances using?
Active transport is the type of transport where a cell must expend energy. These are endocytosis, exocytosis, and the sodium-potassium pump.
What is a general type of transport that does not require an expenditure of energy by the cell?
passive transport

What is it called when the movement of materials through a cell membrane without using the cells energy?
Passive transport does not use energy to pass through a cell membrane. active transport uses energy to pass through a cell membrane.
If the substance entering the cell was in higher concentration inside the cell then outside the cell what type of transport would be required?
It would be active transport, a process which requires a cell to use its own energy (unlike passive transport).
Do molecules need energy to get in and out of the cell?
To clarify the question: the molecules do not need energy to enter or exit the cell, the cells need to spend the energy to get some molecules in or out--however, the answer to your question is: It depends on the molecule, and the cell.Molecules can move into and out of cells by two broad methods: Passive transport, and Active transport.Passive transport requires no energy and involves diffusion (the moving of the molecule from an area of high concentration to low concentration WITH its concentration gradient--it spreads out, into the areas where there isn't any already). One type of diffusion is regular diffusion for molecules that can pass through the membrane (these molecules are said to be "lipophilic" as they interact with the lipid membrane easily). Another type of diffusion is facilitated diffusion--the molecule uses an open channel in the cell to move (does not pass through the membrane by itself). However, the channel is open and does not require energy to function.Active transport requires energy to work. These can be gated channels, "pumps" and other types of transport proteins. Active transport usually moves molecules AGAINST their concentration gradient (from low concentration to high concentration). This is the opposite of diffusion. Remember, the cell is paying this energy debt, not the molecule.In general, lipophilic (hydrophobic) molecules usually do not need energy to cross the cell membrane while lipophobic (hydrophilic) molecules do. The lipophobic molecules often carry a charge (positive or negative) which renders them unable to pass through the membrane, though just a partial charge (polarity) can be enough to keep them in our out. In contrast the lipophilic molecules are electronically neutral and not polar.
