What process do water molecules cross the cell membrane?
Water molecules cross the cell membrane through a process called osmosis, which is driven by the concentration gradient of water inside and outside the cell. Aquaporin proteins on the cell membrane facilitate the movement of water molecules into and out of the cell.
What allows water to cross the permeable membrane of an animal cell?
Water crosses the permeable membrane of an animal cell through a process called osmosis. Osmosis is the movement of water from an area of high concentration to an area of low concentration, across a selectively permeable membrane. This process helps maintain the balance of water inside and outside the cell.
Why does osmosis cross the membrane?
Osmosis occurs across a membrane due to the movement of solvent molecules (usually water) from an area of lower solute concentration to an area of higher solute concentration to equalize the concentration on both sides of the membrane. This process is driven by the tendency of solutes to diffuse and reach equilibrium.
The concentration of molecule x is greater inside a cell than outside. If the cell acquires x from its surroundings x must cross the cell membrane by mean of?
Active transport, which requires energy in the form of ATP. This process allows molecules to move against their concentration gradient from an area of lower concentration to an area of higher concentration.
When a protein channel allows molecules to cross through the cell membrane?
when a protein channel allows molecules to cross through the cell membrane this is called facilitated diffusion. many might mistake this for diffusion which is the process by which molecules tend to move from an area where they are more concentrated to an area where they are less concentrated.
How does oxygen cross the plasma membrane if the concentration of oxygen is lower inside the cell than outside the cell?
Oxygen can cross the plasma membrane through passive diffusion, moving from an area of higher concentration (outside the cell) to an area of lower concentration (inside the cell) until equilibrium is reached. This process does not require energy and occurs due to the difference in oxygen concentrations between the cell's interior and exterior.
What process do water molecules cross the cell membrane?
Water molecules cross the cell membrane through a process called osmosis, which is driven by the concentration gradient of water inside and outside the cell. Aquaporin proteins on the cell membrane facilitate the movement of water molecules into and out of the cell.
The concentration of a sugar is high inside a cell and sightly lower outside the cell What is most likley to occur if the sugar molecule can cross the membrabe?
When sugar molecule crosses the membrane the sugar molecule moves to the outside of the membrane. This is taught in science.
Which type of molecules cross the membrane in osmosis?
Water molecules cross the membrane during osmosis. Osmosis is the movement of water across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
What term describes this action does it require energy?
1.Small lipid molecules are in high concentration outside a cell. They slowly cross the membrance into the cell. 2. Ions are in low concentration outside a cell they move rapidly into the cell via protein molecules.
How can oxygen cross through the membrane?
Oxygen can cross through the membrane via simple diffusion, utilizing a concentration gradient from an area of higher concentration to an area of lower concentration. This passive transport process does not require energy and allows oxygen molecules to move freely across the cell membrane.
What is most likely to occur if the sugar molecules cross the membrane?
Sugar molecules move outside of the membrane.
What is mosly likely to occur if the sugar molecules can cross the membrane?
sugar molecules move outside of the membrane. novanet

This process is driven by the tendency of solutes to diffuse and reach equilibrium.
What are the requirements for materials?
Osmosis occurs when there are two solutions of different concentration strength separated by a semipermeable membrane. The membrane must allow water to cross, but not the solutes. Water will then move from the solution of lower concentration strength across the membrane to the solution of higher concentration strength. This movement of water is called osmosis.
What would happen to a resting membrane potential if the concentration of a large intracellular anions that are unable to cross the membrane experimentally is increased?
If the concentration of large intracellular anions..i.e. proteins, which are unable to cross the membrane due to their large size.. were to increase, the resting potential would reach a more negative state, a deviation from -70mV to a more negative value do to these anions.
