its active transport because it expands in opp direction and pushes
If a substance moves down its concentration gradient, it means that it is moving from an area where it has a high concentration to an area where it has a low concentration. This is known as diffusion.
Passive transport involving facilitated diffusion moves particles up a concentration gradient and requires a carrier protein to facilitate the movement across the cell membrane. This process does not require energy input from the cell.
when the solute passes from a higher solute concentration to a lower solute concentration, it is known as concentration gradient downhill. and the reverse is true for uphill. also, down hill transport requires energy which is derived from ATP. uphill transport is not derived from ATP's rather from the random motion of the molecules themselves.
Simple diffusion
concentration gradient
Passive transport moves down the concentration gradient, from an area of higher concentration to an area of lower concentration.
In biological systems, active transport moves substances against the concentration gradient.
If a substance moves down its concentration gradient, it means that it is moving from an area where it has a high concentration to an area where it has a low concentration. This is known as diffusion.
Passive transport moves with the concentration gradient.
Yes, passive transport moves substances with the concentration gradient.
The low concentration moves down its concentration gradient from an area of high concentration to an area of low concentration. This process is driven by diffusion, where particles move spontaneously from regions of high concentration to regions of low concentration until equilibrium is reached.
Facilitated diffusion moves molecules with the concentration gradient, from an area of high concentration to an area of low concentration.
Yes, active transport moves molecules against the concentration gradient.
Yes, active transport moves substances against the concentration gradient.
Yes, active transport moves substances against their concentration gradient.
Passive transport involving facilitated diffusion moves particles up a concentration gradient and requires a carrier protein to facilitate the movement across the cell membrane. This process does not require energy input from the cell.
the concentration gradient was set-up because they wanted to kill the Jews
