What moves up a concentration gradient and requires a carrier?
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.
What would happen if the concentration of molecules outside the cell was lower than the inside?
the carbon dioxide will move into the cell due to the concentration of carbon dioxide outside of the cell being higher
What is it called When a nutrient moves from an area of higher concentration into an absorptive cell where the concentration is lower?
This process is called active transport. It requires energy to move nutrients against their concentration gradient into the absorptive cell.
What must a cell expand during active transport to accomplish movement of a substance?
During active transport, a cell must expand its energy in the form of ATP to pump molecules or ions across a membrane against their concentration gradient. This process requires energy to create a concentration gradient and move substances from low to high concentration.
What does a difference in concentration in a cell create?
a concentration gradient
How does water leave a cell when in salt water?
Water moves according to an concentration gradient. Water potential gradient between two places
Which process moves an ion across a cell membrane against a concentration gradient?
ative transport
What moves up a concentration gradient and requires a carrier?
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.
A non-energy requiring process that moves materials across a cell membrane with the concentration gradient.?
Passive transport is a non-energy requiring process that moves materials across a cell membrane with the concentration gradient. This process includes simple diffusion, facilitated diffusion, and osmosis.
What would happen if the concentration of molecules outside the cell was lower than the inside?
the carbon dioxide will move into the cell due to the concentration of carbon dioxide outside of the cell being higher
Where do centrioles move?
It moves to a pole of cell.It moves during cell division.
Is water moving from plant cell to plant cell an example of osmosis?
no,because when water moves in a plant cell,it moves from a region of higher concentration(vacuole) to another plant cell.this movements is known as active transport because it against the concentration gradient.
A cell will lose water and shrink size in which solution?
A cell will lose water and shrink in a hypertonic solution, where the solute concentration is higher outside the cell than inside. This creates an osmotic gradient that causes water to move out of the cell, leading to shrinking or shrinking of the cell.
What is the relationship between the electrochemical gradient and the concentration gradient in cellular transport processes?
The electrochemical gradient is a combination of the electrical gradient and the concentration gradient. It influences the movement of ions across cell membranes during cellular transport processes. The concentration gradient refers to the difference in the concentration of ions or molecules inside and outside the cell, while the electrical gradient refers to the difference in charge across the cell membrane. Together, they determine the direction and rate of ion movement in cellular transport processes.
What moves solutes against concentration gradient?
Active transport moves solutes against the concentration gradient by using energy, typically in the form of ATP, to pump molecules across a cell membrane. This process allows cells to maintain specific internal concentrations of molecules that may be higher or lower than the surrounding environment.
What moves products through a cell membrane?
Diffusion, facilitated diffusion, Osmosis and Active Transport. Diffusion moves non-polar molecules across the cell membrane down a concentration gradient. Osmosis moves water across the cell membrane through a channel formed by aquaporins called a protein channel, down the water potential gradient. Active moves the non-polar molecules against the concentration gradient, in contrast to diffusion. Lastly, facilitated diffusion moves polar molecules across the cell membrane through creating protein channels in the cell membrane from specific proteins. ETC, glucose transporters bind to form a protein channel for glucose to diffuse through, after which the proteins disperse. That should be all, hope it was of help!
What does concentration gradient have to do with diffusion of substances across the cell membrane?
The concentration gradient refers to the difference in concentration of a substance between two regions. In the context of cell membranes, substances tend to move from areas of higher concentration to areas of lower concentration to reach equilibrium. This movement is known as diffusion and it is driven by the concentration gradient.
