Which molecules difuse through the lipid portion of the plasma membrane?
Only nonpolar (hydrophobic) molecules can pass through the bi-lipid membrane. For example, hormones are nonpolar, and they can pass through the membrane.
Where does CO2 enter the chloroplast?
It diffuses through the membrane.
How does oxygen get in and out of plasma membrane?
Oxygen, O2, is a small enough molecule that it diffuses diwn it's concentration gradient into the cell and rather easily foes through the plasma membrane. Many small molecules can do this.
When water diffuses through a selectively permeable membrane?
Diffusion without a concentration gradient; osmosis with.
Why do passenger molecules need to be helped by the carrier protein?
Some molecules can't go through the cell membrane.

What molecules that are soluble can pass through the fatty acid portion of the cell membrane unassisted?
Small, non-polar molecules like oxygen, carbon dioxide, and ethanol are soluble and can pass through the fatty acid portion of the cell membrane unassisted. These molecules can diffuse directly through the lipid bilayer due to their hydrophobic nature.
How does oxygen get in and out of plasma membrane?
Oxygen, O2, is a small enough molecule that it diffuses diwn it's concentration gradient into the cell and rather easily foes through the plasma membrane. Many small molecules can do this.
The diffusion of water across a semipermeable membrane is called?
When water diffuses through a semipermeable membrane, such as a cell, it is called osmosis. In osmosis the concentration of water will differ on one side of the membrane from that of the other side. Water molecules will tend to diffuse from the high concentration side to the lower.
The process by which H2O diffuses across a membrane?
Water diffuses across a membrane through a process called osmosis. Osmosis is the movement of water molecules from an area of high concentration to an area of low concentration, down its concentration gradient. This process helps to maintain the balance of water and solute concentrations on both sides of the membrane.
How do small molecules get through the cell membrane against a concentration?
How do small molecules get through a cell membrane
Why do passenger molecules need to be helped by the carrier protein?
Some molecules can't go through the cell membrane.
What kind of particle ion molecule or molecular complex diffuses through a cellulose membrane?
i am not sure
When water diffuses through a selectively permeable membrane?
Diffusion without a concentration gradient; osmosis with.
How is facilitated diffusion differing from diffusion?
Simple diffusion allows non-polar molecules to pass through and a little amount of H20. On the other hand, Facilitated diffusion allows ions and polar molecules across the membrane because it contains carrier proteins. It is highly specific to substances it diffuses across the membrane.
What is the process in which water diffuses through a selectively permeable membrane is called?
The process in which water diffuses through a selectively permeable membrane is called osmosis. Osmosis occurs when water molecules move from an area of higher water concentration to an area of lower water concentration to balance out solute concentrations on either side of the membrane.
