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 the process in which molecules move across the cell membrane from a region of low concentration to a region of high concentration?
Active Transport - the process of moving particles across a cell membrane against a concentration gradient <- right one
What process drives molecules across a membrane against a concentration gradient?
Active Transport.
How can you use water osmosis cell and cell membrane in a sentence?
Water moves in and out of the cell through the cell membrane by the process of osmosis when there is a concentration gradient.
What process is used to move proteins against the concentrarion gradient?
this is called active transport, bc it uses energy and goes against the concentration gradient
What is the process that moves particles from areas of higher concentration?
The answer is is OSMOSIS the spontaneous net movement of water across a membrane from a region of low concentration to a solution with a high concentration, down a solute concentration gradient.
Active transport requires what?
Energy-requiring process by which substances move across the plasma membrane against a concentration gradient.
What moves solutes against concentration gradient?
The processes that can move a solute against its concentration gradient are active transport. All cells are enclosed by a plasma membrane that is similar in structure and function.
Which cell process will remove substances against a concentration gradient?
Active transport
How does stuff knows when to start diffusing?
The process of diffusion occurs when there is a concentration gradient, meaning a difference in the concentration of substances between two areas. The molecules will naturally move from an area of high concentration to an area of low concentration until equilibrium is reached. Therefore, "stuff" starts diffusing when there is a concentration gradient present.
What happens in the process of facilitated diffusion In what part of the membrane does it take place?
In facilitated diffusion, substances will still diffuse down their concentration gradient but they make use of a transport protein.
What is the process that requires cellular energy to move a substance against its concentration gradient?
Active transport uses energy to move substances against the concentration gradient.
Which process moves an ion across a cell membrane against a concentration gradient?
ative transport

Active Transport - the process of moving particles across a cell membrane against a concentration gradient <- right one
What is the process in which molecules move across the cell membrane from a region of low concentration to a region of high concentration?

A non-energy requiring process that moves materials across a cell membrane with the concentration gradient.?
The process of moving materials across the cell membrane without the expenditure of energy is called passive transfer
Compare and contrast active transport and facilitated diffusion-?
Active transport moves solutes against their concentration gradient; facilitated diffusion moves substances down their concentration gradient.
What process drives molecules across a membrane against a concentration gradient?
Active Transport.
