What happens in the process of facilitated diffusion In what part of the membrane does it take place?
In facilitated diffusion, substances will still diffuse down their concentration gradient but they make use of a transport protein.
Compare and contrast active transport and facilitated diffusion-?
Active transport moves solutes against their concentration gradient; facilitated diffusion moves substances down their concentration gradient.
Facilitated diffusion and active transport?
Facilitated diffusion = down concentration gradient, it just uses a carrier protein (doesn't need energy)Active transport =goes UP concentration gradient with the help of a carrier protein and ENERGY
Movement of water down its concentration gradient?
Diffusion is the movement of water from a higher concentration of water to a lower. Osmosis is a special form which requires a cell membrane.
What is diffusion simple?
Simple diffusion is the net movement of substances from a region of high concentration to a region of low concentration so its overall net movement is along the concentration gradient. Simple diffusion does not require energy therefore it is 'passive', substances are diffused across the membrane between the phospholipids.
What term describes the diffusion of the water through a semipermeable membrane down a concentration gradient?
Osmosis is the diffusion of water molecules down a concentration gradient through a semi-permeable membrane
If diffusion is going to occur there has to be what?
A difference in the concentration throughout space because diffusion doesn't just happen in a cell or aqueous solution by definition diffusion is just from high to low concentration
What is an example of diffusion in a sentence?
The rate of diffusion is determined by the permeability of the membrane and the concentration gradient.
What is is required for diffusion to occur?
A concentration gradient and a (semi-)permeable membrane.
What happens in the process of facilitated diffusion In what part of the membrane does it take place?
In facilitated diffusion, substances will still diffuse down their concentration gradient but they make use of a transport protein.
In order for substances to move through the cell membrane what must there be?
For passive diffusion, a concentration gradient which uses pore proteins. For active diffusion, carrier proteins and energy are required.
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.
Compare and contrast active transport and facilitated diffusion-?
Active transport moves solutes against their concentration gradient; facilitated diffusion moves substances down their concentration gradient.
What is osmosis diffusion?
(WATER CELLS ONLY)Water cells move from a higher concentration gradient (more water cells) to a lower concentration gradient (less water cells) through a partially permeable membrane (allows certain substances in and out) and goes with the concentration gradient (high -> low)
Facilitated diffusion and active transport?
Facilitated diffusion = down concentration gradient, it just uses a carrier protein (doesn't need energy)Active transport =goes UP concentration gradient with the help of a carrier protein and ENERGY
Movement of water down its concentration gradient?
Diffusion is the movement of water from a higher concentration of water to a lower. Osmosis is a special form which requires a cell membrane.
Does osmosis require a carrier?
NO. Osmosis( by definition) is the DIFFUSION of water from a high concentration gradient to a low concentration gradient across a semipermeable membrane. As diffusion is a form of passive transport, it doesnt require a carrier
