What are the limitation of simple diffusion using the amoeba as an example?
Simple diffusion really says it for itself. Mostly simple molecules and substances can pass through. Water, O2 or CO2, or other small simple molecules are the limited spectrum of simple diffusion.
What role do carrier protiens play in facilitated diffusion?
facilitated diffusion is also called cell-mediated diffusion because a substance transport in this manner diffuses through the membrane using a specific carrier protein to help.first, carrier protein binds to the binding site of the carrier protein ,and then there is a conformational change in the shape of the carrier protein that helps the molecule to diffuse other side of the membrane.
Toward what condition does diffusion eventually lead in the absence of other influences-?
equilibrium QUEENSCENE: yes, equilibrium because the concentration of molecules will be the same throughout the space the molecules occupy.
What type of protein is used to carry other molecules?
Globular
What is the difference between facilitated diffusion and diffusion?
The difference between diffusion and facilitated diffusion is that facilitated diffusion is that the molecules pass through special protein channels.
The spread of molecules by bumping into each other?
diffusion
Which is a protein of a protein macromolecule?
Transporting other molecules in the body.
What is the difference between simple diffusion and facilitated diffusion?
It doesn't. (answer by RRU member Cyrem)
What state does diffusion eventually lead to?
Well if the diffusion is not interrupted by other influences it would be equilibrium because the concentration of molecules will be the same throughout the space the molecules occupy.
Effect of the presence of other molecules on the diffusion of a given substance?
It explodes
What drives diffusion?
Diffusion is the movement of ions and other micro molecules across a barrier or membrane. Diffusion is caused by gradients on either side of the membrane.
What causes diffusion in the cell?
Diffusion is caused when molecules are moving around and bumping each other in the cell. Collisions cause the molecules to them push apart from one another. Eventually the molecules continue to do this and they spread throughout the area.
Explain the relationship between diffusion and osmosis?
Diffusion is the movement of particles from an area of high concentration to low concentration; osmosis is the same thing, but with water molecules, not other types of molecules.
Molecules tend to move into area where there are more molecules?
That takes energy. Normal diffusion means that the molecules move away from each other (in other words ... to where there are less molecules).
How do diffusion and osmosis related to each other?
Osmosis IS diffusion - except that only certain molecules are allowed to pass through the membrane.
How do diffusion and osmosis affect cells?
diffusion does the thing and osmosis does the other one. 10/10 gameinformer
How is facilitated diffusion different from passive transport?
Mediated Transport has an extra step of binding to a carrier protein, while Passive transport does not bind to a protein. Both of them however, move along the concentration gradient (High--> Low)
