What else can I help you with?
What is is required for diffusion to occur?
A concentration gradient and a (semi-)permeable membrane.
What drives Facilitated diffusion?
Facilitated diffusion is a passive process whereby a molecule is "carried" across a semi-permeable membrane by a channel or protein carrier. Like diffusion, this process requires no energy, however, since passive diffusion can drive movement against a concentration gradient it is not really diffusion.
In order for substances to move through the cell membrane what must there be?
For substances to move through the cell membrane, there must be a concentration gradient, as substances will naturally move from an area of higher concentration to lower concentration through processes like diffusion or facilitated diffusion. Additionally, specific transport proteins or channels may be required depending on the size or charge of the substance being transported.
Energy is blank from the cell for passive transport?
Energy is not required for passive transport, as it occurs naturally due to the concentration gradient without the cell expending energy. Examples of passive transport include simple diffusion, facilitated diffusion, and osmosis.
How is facilitated diffusion different than normal diffusion?
Diffusion is the movement of molecules or partocles from an area of high concentration to an area of lower concentration, and Facilitated diffusion is when substances difuse across cell membranes more rapidly than you might expect.

Is it true diffusion is a type of active transport?
Yes except, diffusion is a passive process (no energy is required) whereas active transport requires energy. this is because it is moving UP then concentration gradient whereas diffusion moves DOWN it
What is the random movement of molecules and ions down their concentration gradient called?
The random movement of molecules and ions down their concentration gradient (meaning from an area of high concentration to an area of low concentration) is called simple diffusion. Simple diffusion is related to the magnitude of driving force, permeability of the membrane, and surface area.

Which of the following required the most ATP to move the molecule across a plasma membrane?
Ion moving against a concentration gradient
Does passive transport rely on diffusion or energy?
No it does not..........simple diffusion is nauture

Energy is always required to force molecules to move from areas of high concentration to areas of low concentration true or false?
False. Energy is not required to move molecules from areas of high concentration to areas of low concentration; this process occurs naturally through diffusion, which is driven by the concentration gradient. However, energy is required for active transport, where molecules are moved against their concentration gradient from low to high concentration.
How are facilitated diffusion and active transport similar ad how do the differ?
both these processes do the transport against the concentration gradient uh no facilitated diffusion doesnt go against the gradient, the similiarity is that they both use carrier protiens
