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 substances through a cell membrane along a concentration gradient with the aid of carrier proteins?
Facilitated Diffusion is the answer
What is the transport of substances through a cell membrane along a concentration gradient with the aid of c carrier proteins?
Facilitated Diffusion
What regulates the rate of passive transport?
the concentration gradient and the membrane
What is the movement of chemical substances usually across the cell membrane againts a concentration gradient requires cells to energy?
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.
How does difference in concentration relate to movement of substances across the membrane?
the concentration gradient will help to bring stuff into the cell and to move stuff out. Osmosis likes to move with the concentration gradient. Moving with a concentration gradient is passive transport and moving against it is active transport

Facilitated Diffusion is the answer
Active transport requires what?
Energy-requiring process by which substances move across the plasma membrane against a concentration gradient.

What regulates the rate of passive transport?
the concentration gradient and the membrane
What is the movement of chemical substances usually across the cell membrane againts a concentration gradient requires cells to energy?
active transport
How plasma proteins regulate osmotic pressure?
They transport substances across the membrane which changes the concentration gradient and thus the osmotic pressure.
Describe active transport?
Active transport is described as the movement of substances against their concentration gradient. This is movement of molecules from low concentration to high concentrationActive transport is the process of moving molecules from a low concentration to a high concentration across a cell membrane.
What movement of the substances through a cell membrane against a concentration gradient requires energy?
The movement of a substance through a cell membrane against its concentration gradient is called active transport. Primary active transport requires energy, usually in the form of ATP. Secondary active transport makes use of another substance moving down its concentration gradient to pump a substance against its concentration gradient.
What are the 2 kinds of cellular transport?
The two kinds of cellular transport are; active and passive transport.Active transport - is the net movement of dissolved substances into or out of cells against a concentration gradient. Because the net movement is against a concentration gradient (low to high concentration), active transport requires energy.Passive transport - is the movement of dissolve substances from a region of high concentration, across a plasma membrane, to a region of low concentration without the expenditure of energy.
What functions do carrier proteins perform in active transport?
Carrier proteins of the cell membrane transport substances down their concentration gradient out of or into the cell by facilitated diffusion and active transport.
