Active Transport- When molecules move from an area of lower concentration to an area of higher concentrationPassive Transport- When molecules move from an area of higher concentration ot an area of higher concentration (also called diffusion)
Active transport is needed to move molecules from an area of low concentration to an area of higher concentration against their concentration gradient. ATP is used as the power source.
when the solute passes from a higher solute concentration to a lower solute concentration, it is known as concentration gradient downhill. and the reverse is true for uphill. also, down hill transport requires energy which is derived from ATP. uphill transport is not derived from ATP's rather from the random motion of the molecules themselves.
Primary Active Transport.
Facilitated diffusion requires energy. This is because facilitated diffusion is the transfer of molecules from a lower concentration to a higher concentration.membrain pouch
Active transport requires more energy than diffusion this is because during active transport, the molecules are being transported against and toward the concentration gradient whereas in diffusion, the molecules go from the concentration gradient.

Active transport is needed to move molecules from an area of low concentration to an area of higher concentration against their concentration gradient. ATP is used as the power source.
Diffusion is the movement of molecules from areas of high concentration to areas of low concentration and active transport is the movement of molecules from an area of low concentration to an area of high concentration
Simple diffusion = flow of small molecules ALONG the concentration gradient, does NOT require energy. facilitated diffusion = flow of molecules ALONG the concentration gradient with help of CARRIER PROTIENS or CHANNELS, does NOT require energy active transport= flow of larger or charged molecules AGAINST their concentration gradient, REQUIRES input of ENERGY in the form of ATP.)
In active transport the ATP is used to pump molecules up the concentration gradient. Transport of molecules occurs from a low concentration of solute to high concentration of solute and requires cellular energy. While passive transport involves carriers, channels, or direct diffusion through a membrane.
Active transport is used to move molecules and ions across a membrane against their concentration gradient. "Active" means that the transporter requires energy to do its job (eg. glucose).
The process of moving materials against a concentration gradient is called active transport. Active transport generally uses a protein pump to move molecules from an area of low concentration to an area of high concentration; in order to perform an active transport, the cell must use some of its energy to initiate the reaction.

Active transport requires energy and Passive transport requires no energy.Passive transport is a process which is carried out along the concentration gradient. For example, if the concentration of water is more outside the cell than inside, water will flow into the cell. Simply put, it is actually diffusion which occurs in passive transport and hence, no energy is required.Active transport, however, is carried out against the concentration gradient and hence requires energy. An example of active transport is the uptake of salt by cells through sodium pump.Active transport requires energy and moves particles up their concentration gradient. Passive transport doesn't require energy and moves particles down their concentration gradient.
Primary Active Transport.
Active transport requires ATP and passive transport does not. Active transport goes against the concentration gradient and passive transport goes with the concentration gradient and includes osmosis, diffusion and facilitated diffusion.
