Osmosis is an example of movement of particles from an area without the need of additional energy. If a state is not in equilibrium particles can move from one area to another without additional energy.

Do cells gain and then use energy through facilitated diffusion?
Cells do not gain (or use) energy through facilitated diffusion.
What is the differences between simple and active diffusion?
Simple diffusion is the passive movement of molecules from an area of higher concentration to an area of lower concentration without the use of a protein carrier. Active diffusion, on the other hand, requires energy input and often utilizes protein carriers to move molecules against their concentration gradient, from an area of lower concentration to an area of higher concentration.
Does passive transport take place without the use of energy?
Yes, passive transport does not require energy input from the cell. This type of transport relies on diffusion and osmosis to move substances across the cell membrane, driven by concentration gradients.
Does the facialited diffusion require the cell to use energy?
No, it does not require energy use from the cell.
Does a cell use energy when molecules diffuse in or out of the cell down the concentration gradient?
Diffusion is passive transport - it means that the cell doesn't use any energy transporting the materials. However, if there is more of a substance inside a cell than outside a cell (like nutrients), and the cell needs to get the nutrients in, diffusion will not owrk. The cell uses energy to do active transport and get the particles in.
What statements tells how facilitated diffusion differ from simple diffusion?
Particles move through cell membranes w/out the use of energy by cells.
What structures allow small particles to cross the cell membrane?
Small particles can cross the cell membrane through simple diffusion, facilitated diffusion, or active transport. In simple diffusion, particles move from an area of high concentration to low concentration without the need for energy. Facilitated diffusion involves the use of protein channels or carriers to aid in the movement of particles. Active transport requires energy and transport proteins to move particles against their concentration gradient.
How is diffusion SIMILAR to osmosis?
Neither of them require energy. that is the major difference.
What is it called when large particles need to use energy to pass through cell membranes?
Active Diffusion
How does osmosis and diffusion occur without the use of energy?
Osmosis and diffusion are passive processes that occur without the use of energy because they rely on the natural movement of particles from an area of higher concentration to an area of lower concentration, driven by the principle of entropy. In osmosis, the movement of water molecules across a selectively permeable membrane occurs due to differences in solute concentrations on either side of the membrane. In diffusion, molecules move from regions of higher concentration to lower concentration until equilibrium is reached, without the need for energy input.
What is the movement called when a call does not use energy to move particles across the cells membrane?
It is called passive diffusion.
What is the movement called when a cell does not use energy to move particles across the cell's membrane?
It is called passive diffusion.
Is endocytosis an example of diffusion?
Endocytosis is not an example of diffusion. Endocytosis is a process by which cells take in molecules or particles by engulfing them in vesicles. Diffusion, on the other hand, is the passive movement of molecules from an area of higher concentration to an area of lower concentration.
Why do cells use the process of diffusion?
Diffusion is essential for cells to bring nutrients and releasing wastes without spending energy.
What kind of energy does diffusion use?
Diffusion is a passive process that uses kinetic energy from the random movement of particles to spread substances from an area of high concentration to an area of low concentration. No external energy input is required for diffusion to occur.
Does faciliated diffusion require energy?
Facilitated diffusion does not require energy because it relies on the use of carrier proteins to transport molecules across a cell membrane down their concentration gradient. These carrier proteins facilitate the movement of specific molecules such as glucose or ions without the need for ATP or energy input.
What is the process in which particles in gas or liquid moves from higher to lower concentration?
Particles in a gas or liquid moving from a region of higher concentration to a region of lower concentration represents passive transport. This does not use energy.
