This is known as active transport and requires energy usually in the form of ATP. It can also use the potential energy generated across a membrane by the transport of a different ion (either symport or antiport).

The transport of a substance across the cell membrane against its concentration gradient is called what?
The transport of a substance across the cell membrane against its concentration gradient is called active transport.
What is the transport of materials against a concentration gradient called?
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.
In order for molecules to move against the concentration gradient?
When you have one concentration (amount) of a molecule, connected to a higher or lower concentration through a permeable membrane (bridge), there is a natural force (heat) pushing the molecules to go from the higher concentration to the lower concentration until both sides have balanced (it is also called diffusion, this process is related to the laws of thermodynamics). Anyway this force the measurement of force for this movement is called the concentration gradient. For a molecule to move against this natural force is to against the concentration gradient, it requires an energy GREATER then that from diffusion or heat to push it. An example would be when there is an opposing electrical force strong enough that may push an electrically charged molecule against its concentration gradient.
What proceeds against a concentration gradient?
Molecules can move against concentration gradient by a movement called active transport. Molecules move from an area of low concentration to an area of high concentration by using chemical energy called ATP or an electrochemical gradient--either way, it uses cellular energy.
What is the difference in the concentration of a substance across a space is called concentration?
Concentration Gradient
What process drives molecules across a membrane against a concentration gradient?
Active Transport.
The transport of a substance across the cell membrane against its concentration gradient is called what?
The transport of a substance across the cell membrane against its concentration gradient is called active transport.
In which type of process do substances move down their concentration gradient across the membrane?
Active transport is a process that removes substances from a cell against the concentration gradient. The molecules move from low concentration to high concentration during this process.
What is water uptake at the roots?
water uptake at the roots is called osmosis,this is the movement of water molecules from a region of lower concentration to a region of higher concentration against concentration gradient

Concentration Gradient
The difference in concentration of a substance across space is called a?
it is called a concentration gradient.
What is a differences in concentration called?
concentration gradient
What is the process by which molecules move from high concentration region to low concentration region without the presence of membrane?
This process is called diffusion. It is the passive movement of particles from high to low concentration, and is against a concentration gradient. Hope this helps!
Does active transport move from higher to lower concentration?
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)
