When particles move out of a cell through facilitated diffusion, the cell __________.
A>> first gains and then uses energy
B>> does not use energy
C>> gains energy
D>> uses energy
I'm thinking it's A...
so then it does not use energy, right?
Doesn’t gain energy
Gain energy
A
You are correct! When particles move out of a cell through facilitated diffusion, the cell does not use energy. Facilitated diffusion is a form of passive transport, which means it does not require energy expenditure by the cell. In facilitated diffusion, specific carrier proteins embedded in the cell membrane facilitate the movement of particles from an area of higher concentration to an area of lower concentration. This process allows the particles to move down their concentration gradient, without the cell needing to exert any energy.
wtf is tha answer bluud?
Which type of diffusion does not require energy but does need assistance?
Simple Diffusion. One example of passive transport is diffusion, when molecules move from an area of high concentration (large amount) to an area of low concentration (low amount). ... Simple diffusion does not require energy or need the assistance of a transport protein.
