active transport
Because facilitated diffusion moves moolecules from regions of higher concentration toward lower concentration, active transport moves particles through membranes from region of lower concentration to a region of higher concentration
osmosis is the passive movement of a substance from a place where its concentration is higher, to another where its concentration is lower. This applies to gases, I guess
The concentration gradient determines the direction in which a substance diffuses across a membrane. The concentration gradient is a measure of how the concentration of a substance changes from one place to another.
The movement of materials from a higher concentration to a lower concentration is called diffusion. This process occurs spontaneously to reach equilibrium, where the concentration of the substance is the same throughout the system.
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)
Facilitated transport occurs when a substance moves from an area of higher concentration to an area of lower without the aid of energy. Active transport involves additional energy as it is moving from a lower concentration into a higher concentration.
This process is known as active transport. It requires energy to move substances against their concentration gradient, from an area of lower concentration to an area of higher concentration. Examples include the sodium-potassium pump in cells.
Because facilitated diffusion moves moolecules from regions of higher concentration toward lower concentration, active transport moves particles through membranes from region of lower concentration to a region of higher concentration
The difference in concentration of a substance across space is called a concentration gradient. This gradient drives the movement of molecules from regions of higher concentration to regions of lower concentration through processes like diffusion or active transport.
Osmosis
Passive transport moves down the concentration gradient, from an area of higher concentration to an area of lower concentration.
Active transport. This process uses energy to pump substances against their concentration gradient, allowing them to move from areas of lower concentration to higher concentration.
A kind of transport by which ions or molecules move along a concentration gradient, which meansmovement from an area of higher concentration to an area of lower concentration.

Active transport is the movement of materials against a concentration difference. Active transport requires the cells energy. So when there is a higher concentration of something on one side of the cell, the cell will move it to a place where there is a lower concentration of the substance. This way it keeps everything balanced.
This is called a concentration gradient, which represents the difference in concentration of a substance between two locations. The substance will naturally move down the concentration gradient from areas of higher concentration to lower concentration through processes like diffusion or active transport.
When a substance moves from an area of low concentration to an area of high concentration while using energy the process is called active transport.
