What else can I help you with?
When does diffusion occur across a cell membrane?
Diffusion across a cell membrane occurs when concentrations of a substance are higher either inside or outside the cell.
What part of the cell does osmosis occur?
it occurs in the cell membrane(through the cell membrane really)
In which organelle does osmosis occur?
Osmosis occurs in the cell membrane of a cell. It is the movement of water across the cell membrane, which controls the balance of water inside and outside of the cell.
What does a carrier protein do in the process of transporting molecules across a cell membrane?
A carrier protein helps transport molecules across a cell membrane by binding to specific molecules and changing shape to move them across the membrane.
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 is the process of water diffusing across a what membrane?
Water diffuses across a cell membrane through a process called osmosis. Osmosis is the movement of water molecules from an area of high water concentration to an area of lower water concentration, driven by the concentration gradient of solutes across the membrane. This process helps maintain the cell's internal environment and balance the concentration of solutes inside and outside the cell.
Movement of a substance across a cell membrane using chemical energy occurs during?
Active transport is the movement of a substance across a cell membrane using chemical energy. This process requires the use of a carrier protein and ATP to transport molecules against their concentration gradient.
Net movement of water across a cell membrane occurs from what?
The net movement of water across a cell membrane occurs from an area of lower solute concentration to an area of higher solute concentration. This process is driven by the osmotic pressure gradient between the two sides of the membrane.
Net movement of water across a cell membrane occurs?
from a hypotonic solution to a hypertonic solution.
What is equilibrium with respect to movement of molecules across a cell membrane?
that happens when osmosis occurs
What is the process in which molecules move across the cell membrane from a region of low concentration to a region of high concentration?
Active Transport - the process of moving particles across a cell membrane against a concentration gradient <- right one
Is the process in which molecules move across a cell membrane from a region of low concentration to a region of high concentration.?
