Do molecules move at equilibrium during diffusion?
Since diffusion moves materials from an area of higher concentration to the lower, it is described as moving solutes “down the concentration gradient.” The end result of diffusion is an equal concentration, or equilibrium, of molecules on both sides of the membrane. At equilibrium, movement of molecules does not stop.
Which direction will molecules want to move?
Molecules will always move down the concentration gradient, toward areas of lesser concentration.
What does it mean when substances move toward equilibrium?
Equilibrium by definition is the state of a chemical reaction in which its forward and reverse reactions occur at equal rates so that the concentration of the reactants and products does not change with time; however, in the living organisms, equilibrium is hardly achieved since the condition is always changing.
How do you know when a solution has reached equilibrium?
Q can be used to determine which direction a reaction will shift to reach equilibrium. If K > Q, a reaction will proceed forward, converting reactants into products. If K < Q, the reaction will proceed in the reverse direction, converting products into reactants. If Q = K then the system is already at equilibrium.
What is Diffusional equilibrium?
Definition. noun. The state in which the concentrations of the diffusing substance in the two compartments are the same or become equal. Supplement.
Do you expect water to continue to flow across the semipermeable lipid bilayer after osmotic equilibrium is reached?
Since there is no difference in [solute] there will be no osmotic flow of water, but water will still move between the two chambers because the membrane is freely permeable to water.
When comparing two solutions on different sides of a membrane The solution that has less solute and a higher water concentration?
But now you have two mixtures of different solute concentrations. In comparing two solutions of unequal solute concentration, the solution with the higher solute concentration is hypertonic, and the solution with the lower solute concentration is hypotonic.
Where are proteins Synthesised in the cell how are they transported?
Translation is the process of protein synthesis from mRNA. Protein synthesis occurs in the cytoplasm where ribosomes play a major role. The mRNAs synthesized in nucleus gets transported to the cytoplasm where protein synthesis takes place.
