Is simple diffusion the net diffusion of a solvent?
no
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.
The movement of oxygen into cells from the bloodstream is accomplished through?
Diffusion, specifically simple diffusion
What is the transport that moves a solute down the concentration gradient?
Simple diffusion
Two types of passive transports are?
PASSIVE TRANSPORTS ARE OF TWO TYPES. 1)SIMPLE DIFFUSION 2)FACILITATED DIFFUSION 1)SIMPLE DIFFUSION:-diffusion of water and dissolved gas is simple. when concentration on both sides of membrane becomes the same,it stops. 2)FACILITATED DIFFUSION:-this also occurs along concentration gradient with help of carrier molecules.
What is the similarity between simple diffusion and facilitated diffusion?
both need transport protein
How does faciliated diffusion differ from simple diffusion?
Facilitated diffusion needs some sort of help. Often it would be a protein. Simple diffusion doesn't. If you spill something smelly on the floor in the kitchen, you will smell it all through the house. It will spread by simple diffusion.
This is the process whereby a protein assists in simple diffusion?
Active transport
What are the three transport processes that do not require cell energy?
Passive Transport,Facilitated Diffusion, and Simple Diffusion
Does simple diffusion require ATP?
No only active transport requires ATP.
How is faciliated transport similar to simple diffusion?
Facilitated and simple diffusion both transport solutes along a concentration gradient and neither processes require any ATP expenditure.
How is active transport different than simple and facilitated diffusion?
simple and facilitated diffusion don't require energy and are forms of passive transport. Active transport requires energy
What are the 2 types of diffusion and explain fully?
simple and fascillitated simple--> doesn't need help from protein channels on cell membranes
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.
Does passive transport rely on diffusion or energy?
No it does not..........simple diffusion is nauture
Is facilitated diffusion type of active transport?
Facilitated diffusion is passive transport as no energy is used, and a protein channel is all that's required. After that it is simple diffusion down a concentration gradient. Anything with the word diffusion in it is passive transport. Diffusion is just the principle of passive transport.
What help maintain homeostasis in cells does not require energy?
Simple diffusion and osmosis help maintain homeostasis in cells and do not require the cell to expend energy.
