What kind of concentration forms whenever there is a difference in concentration between one place and another?
A gradient forms when there is a difference in concentration between two places. This gradient drives the movement of substances from areas of higher concentration to areas of lower concentration through processes such as diffusion or osmosis.
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.
What is the direction of net osmosis?
Osmosis is the passage of water from the region of high water concentration through a semi permeable membrane to a region of low water concentration. The direction of movement is from area of higher water concentration to area of lower water concentration.
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.
In osmosis explain why water moves toward a hypotonic area?
Osmosis is the net movement of water through a selectively permeable membrane from a region of higher water concentration (less solute) to a region of lower water concentration (more solute). And since hypertonic means that there is more solute inside the cell, the solute will try to exit to balance the concentration.
What is the difference between the concentration of a particular molecule in one area and the concentration in an adjacent area?
The concentration gradient is the difference in concentration of a molecule between one area and an adjacent area. This difference creates a gradient that drives the movement of molecules from an area of higher concentration to an area of lower concentration, a process known as diffusion.
What kind of concentration forms whenever there is a difference in concentration between one place and another?
A gradient forms when there is a difference in concentration between two places. This gradient drives the movement of substances from areas of higher concentration to areas of lower concentration through processes such as diffusion or osmosis.
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
How would diffusion differ from osmosis?
Osmosis is the net movement of water molecules across a semipermeable membrane from a region of a lower concentration to a higher concentration. Diffusion is the movement of particles from a region of higher concentration to a region of lower concentration down a concentration gradient
COMPARE osmosis and diffusion?
Diffusion is movement of molecules, from region of higher concentration, to the region of lower concentration, along concentration gradient.
Can you have diffusion without osmosis?
Osmosis is the movement of water molecules across a semipermeable membrane from a region of higher concentration to a region of lower concentration. Diffusion is the movement of any molecules from a region of higher concentration to a region of lower concentration. so yes it is possible to have diffusion without osmosis.
Why must cells use energy to move particles from a region of lower concentration to a region of higher concentration?
equilibrium
Why must cells use energy to move particles from region of lower concentration to a region of higher concentration?
equilibrium
Movement of ions from a region of higher concentration to a region of lower concentration via a process that does not require cellular energy is?
osmosis
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 is the difference of concentration of a solute from one region to another?
The difference in concentration of a solute from one region to another is known as a concentration gradient. This gradient occurs when there is a higher concentration of solute in one area compared to another, creating a potential for movement. Solutes tend to move from regions of higher concentration to regions of lower concentration, often through processes like diffusion or osmosis, until equilibrium is reached. The steeper the gradient, the faster the rate of movement of the solute.
Which process would describe the movement of sugar molecules through a membrane from a region of higher concentration of a region of lower concentration?
Diffusion
