When materials move passively by diffusion in what dirction do they go through the cell?
the direction depends on the concentration of materials, materials moved by diffusion move from a region of high concentration to a region of low concentration
Diffusion allows materials to?
actually diffusion allows materials to move in and out of the cell
In passive transport materials move from an area of higher concentration to an area of lower concentration through a cell membrane.?
yes
Why is it easier to move materials across membranes down a concentration gradient?
osmotic pressure
How does most water soluble materials get into a cell process by which molecules tend to move from an area of higher concentration to an area of lower concentration?
Diffusion

yes

osmotic pressure
How do materials move in and out of a cell?
they usually don't.
How does most water soluble materials get into a cell process by which molecules tend to move from an area of higher concentration to an area of lower concentration?
Diffusion
In materials move from an area of higher concentration to an area of lower concentration through a cell membrane.?
Through the process of mitosis.
What is required when cells must move materials against a concentration gradient?
Active transport which requires ATP.
Materials can be moved from a low concentration to a high concentration through?
The process that is able to move materials from low concentration to high concentration is called active transport. Active transport uses energy while diffusion does not use energy.
How does fat move in the molecules?
Molecules usually move from high concentration to lower concentrations. East-side
How molecules moved?
Molecules usually move from high concentration to lower concentrations.
How do transport proteins that are pumps differ from that are channels?
Transport proteins that are pumps differ from those that are channels in that when it pumps, it moves materials against concentration gradient. Other wise, from low to high concentration levels. Channels move materials down a concentration gradient, requiring no energy expenditure by the cell. From high concentration to low concentration levels.
