Does osmosis or facilitated diffusion require the presence of membrane channels?
facilitated diffusion
The process that occurs when a physical pressure pushes materials through a barrier is called?
Osmosis is the movement of water across the membrane, while diffusion is the movement of solids across a membrane Diffusion ordinarily does not require a membrane.The movement of particles of a substance by their own kinetic energy from their higher concentration to lower concentration is called diffusion.
What is this statement most likely referring to Small nonpolar molecules may pass through this structure but others require a protein channel?
Small non-polar molecules may pass through a a semipermeable membrane but others require a protein channel.
If a chemist wants to study dissfusion should a semipermeable membrane be used?
Diffusion is essentially the movement of solute molecules from a region of higher concentration to a region of lower concentration. A semi permeable membrane need not be used to study this phenomenon
What are two way diffusion and osmosis are the same?
Osmosis is just a form of diffusion. They are both the movement of substances and both require a concentration gradient.
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
Does osmosis or facilitated diffusion require the presence of membrane channels?
facilitated diffusion
Is osmosis a passive or active transport and how?
The four main kinds of passive transport are diffusion, facilitated diffusion, filtration and osmosis. Osmosis always deals with the movement of water across a semipermeable membrane. Water always moves toward the side that is higher in solutes (mainly salt). It does this to balance the two sides. Osmosis always follows salt is one of the best ways to remember this.
What process requires membrane proteins but not energy?
Osmosis is the membrane activity that does not require the expenditure of energy by the cell. It does not require any input of energy.
What two processes transport materials through the semi-permable membrane?
Considering the cell membrane itself, processes include diffusion, osmosis, facilitated diffusion (passive processes that do not require energy) and active transport (an active process that requires energy).
Are diffusion and osmosis passive or active transports?
Diffusion and osmosis are passive and do not require energy.
Does osmosis require protein?
Nope! Osmosis is simply the movement of H2O over a membrane from high concentration to low concentration. It's a form of passive diffusion!
What is the difference between active transport and osmosis?
Osmosis is the diffusion of water across a membrane, and does not require the input of energy. Active transport requires energy input.
Osmosis does not require what?
Osmosis does not require a cell to expand its own energy. Osmosis is a type of diffusion process for water.
Does osmosis require membrane proteins?
No, osmosis is a special type of diffusion in which a water molecule is able to passively transport through a membrane without a protein. Although it is polar, it's extremely small size makes this possible
Distinguish between osmosis and diffusion?
The difference between Diffusion and Osmosis is by the process of them diffusing and the outcome such as an example of a sugar cube... In Diffusion Molecules move from high concentration just Osmosis although in the diffusion process of "Diffusion" it uses Kinetic energy and Concentration Gradient while "Osmosis" does not require cells to expand energy, in result Osmosis uses Passive Transport of Water.
How the terms in each pair differ in meaning of osmosis and diffusion?
Osmosis is the diffusion of water through a selectively permeable membrane. Diffusion refers to the simple property of moving from an area of high concentration to an area of low concentration so that the concentration of the total area will be equal and balanced (at equilibrium). Diffusion can occur with any substance and does not require but can involve a permeable membrane.
