What three things can affect the rate of diffusion?
Diffusion refers to the process where substances from a highly concentrated area move to a place with a lower concentration. The three factors that affect the rate of diffusion are temperature, concentration gradient and the molecular weight of the substances.
In which type of process do substances move down their concentration gradient across the membrane?
Active transport is a process that removes substances from a cell against the concentration gradient. The molecules move from low concentration to high concentration during this process.
What is the net movement of substances to regions of lower concentration called?
This process is called diffusion. If the substance moving is water, it is called osmosis.
What is concerntration gradient?
As used in the process of diffusion, the concentration gradient is the graduated difference in concentration of a solute within a solution (as expressed per a unit distance). Molecules tend to move from areas of greater concentration to areas of lesser concentration. i.e. down the gradient.
How do substances move in a cell?
By Diffusion and Osmosis.Diffusion is literally a "process of scattering" (diffus). The scattering process of diffusion arises from the fact that all particles are constantly moving in random directions. During diffusion, particles move by chance from a region where their concentration is high, to a region where their concentration is low.osmosis -is the net movement of water molecules across a semipermeable membrane from a region of a higher concentration to a region of lower concentration...
Which process uses proteins to move molecules against a concentration gradients?
active transport

Which cell process will remove substances against a concentration gradient?
Active transport
What is osmosis in science?
The term osmosis refer to an entropy driven process by which substances tend to move from a region of high concentration to a region of lower concentration.
What is the process that requires cellular energy to move a substance against its concentration gradient?
Active transport uses energy to move substances against the concentration gradient.
What name is given to the process by which substances pass into or out of a cell from an area of higher concentration to an area of lower concentration?
diffusion
What factors affect the diffusion rate?
Diffusion refers to the process where substances from a highly concentrated area move to a place with a lower concentration. The three factors that affect the rate of diffusion are temperature, concentration gradient and the molecular weight of the substances.
Active transport requires what?
Energy-requiring process by which substances move across the plasma membrane against a concentration gradient.
Why does water generally move in the opposite direction of dissolved substances?
Diffusion is the process of a substance moving from an area of a higher concentration to a lower concentration. In this scenario the dissolved substance is the higher concentration and the water would go to an area with the lower concentration.
What is the net movement of substances to regions of lower concentration called?
This process is called diffusion. If the substance moving is water, it is called osmosis.
What is concerntration gradient?
As used in the process of diffusion, the concentration gradient is the graduated difference in concentration of a solute within a solution (as expressed per a unit distance). Molecules tend to move from areas of greater concentration to areas of lesser concentration. i.e. down the gradient.
