Active transport. It requires energy in the form of ATP to move molecules or ions against their concentration gradient from an area of lower concentration to an area of higher concentration.

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.
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.
Does Passive transport uses ATP to move molecules against their concentration gradient?
No, passive transport does not require ATP because it moves molecules along their concentration gradient, from an area of higher concentration to an area of lower concentration. ATP is only required for active transport, which moves molecules against their concentration gradient.
What process moves materials through a cell from areas of low concentration to a higher concentration area?
active transport
What id the difference between active and passive transport?
Active transport requires energy to move molecules against their concentration gradient while passive transport does not require energy and moves molecules from high to low concentration. Active transport is selective and can transport specific molecules, while passive transport is nonselective and moves molecules based on their concentration gradient.
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.
Which transport mechanisms moves materials across a plasma membrane against an apparent 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.
What is required when cells must move materials against a concentration gradient?
Active transport which requires ATP.
How do transport proteins that are pumps differ from that are channels?
Transport proteins that are pumps differ from those that are channels in that when it pumps, it moves materials against concentration gradient. Other wise, from low to high concentration levels. Channels move materials down a concentration gradient, requiring no energy expenditure by the cell. From high concentration to low concentration levels.

What is a characteristic that diffusion and active transport have in common and both process?
Both involve the transport of materials across the cell membrane. Active transport goes against the concentration gradient and requires ATP. Diffusion goes with the concentration gradient, or from high to low concentration, and does not require ATP. ATP is the standard unit of energy in cells.
What process is used to go against the concentration gradient?
active transport
Moving particles from a place of lower to higher concentration using energy is what process?
The answer is active transports because it goes from high to low concentration h ope 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)
What process moves materials through a cell from areas of low concentration to a higher concentration area?
active transport
