What influences diffusion?
Diffusion is a type of passive transport. The factors that influence diffusion include: concentration gradient, size of molecule involved, distance the molecule has to travel, temperature, solubility of the molecule and surface area.
What is the most common type of molecule present in the bacteria cell membranes?
A lipid is the most common type of molecule present in the bacteria cell membranes.
Which structure is the statement below most likely referring to A large glucose molecule requires facilitated diffusion but an oxygen molecule does not.?
A semipermeable membrane is a large glucose molecule that requires facilitated diffusion but an oxygen molecule does not.
What types of molecules diffuse through the cell membranes by facilitated diffusion?
molecules that can survive the hydrophobic interior of the lipid bilayer
What molecule crosses the plasma membrane by diffusion?
water
Does sugar diffuse through the cell membrane?
No. Only non-polar, small molecules can pass through a membrane by simple diffusion. A sucrose molecule is too large a molecule to pass through a membrane by simple diffusion, however, it can pass through a plasma membrane (but not any artificial membranes like Visking tubings) by facilitated diffusion, i.e. through transport proteins(specific carriers for sucrose) embedded in the membranes. ! =)
What are three types of passive transport?
Diffusion- is the movement of the substance from an area of higher concentration to an area of lower concentration,Osmosis- is the diffusion of water molecule only through a membrane semipermeable cell membranes allow water to pass through them until equilibrium occurs.Facilitated Diffusion- carrier proteins, and channel proteins it occurs when molecule pass through a cells membrane.

A semipermeable membrane is a large glucose molecule that requires facilitated diffusion but an oxygen molecule does not.
How are osmosis and diffusion defferent?
by... osmosis is the diffusion of water molecule across and athe diffusion is the process by which molecules speards from area
What structure is the statement below most likely referring to A large glucose molecule requires facilitated diffusion but an oxygen molecule does not?
A large glucose molecule requires facilitated diffusion but an oxygen molecule does not is a semipermeable membrane.
What is he predominant molecule comprising cell membranes?
Lipid.
What molecules need facilitated diffusion to move across the plasma membrane?
the process through which the molecule move from a higher concentrated to low concentrated is called as Osmosis. the same molecule when move from a high concentration to lower one is called as Reverse Osmosis.
The process where a nonpolar molecule can just passively get across a membrane is called?
facilitated diffusion
What types of molecules diffuse through the cell membranes by facilitated diffusion?
molecules that can survive the hydrophobic interior of the lipid bilayer
What molecule crosses the plasma membrane by diffusion?
water
