How are facilitated diffusion and active transport different?
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
What movement of gas molecules from a region of higher concentration to a region of lower 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
What determines the direction in a substance diffuses across a membrane?
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.
What is the movement of materials from a higher to a lower concentration?
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.
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)
How does facilitate transport differ from active transport?
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.
What is the movement of substance from a region of lower concentration to a region 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.
How are facilitated diffusion and active transport different?
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?
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.
What is the process by which a substance moves from a level of higher concentration to a level of lower concentration?
Osmosis
Does passive transport move up or down the concentration gradient?
Passive transport moves down the concentration gradient, from an area of higher concentration to an area of lower concentration.
Moving substances from a lower concentration to a higher concentration requires . passive diffusion facilitated diffusion active transport pinocytosis?
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.
What is transported in passive transport?
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.
What movement of gas molecules from a region of higher concentration to a region of lower 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
What is in Active transports?
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.
When the concentration of a substance differs from one area to another this is called concentration?
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 processed is term is?
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.
