What effect does increasing NaCl concentration have on osmotic pressure Why?
Increasing the NaCl concentration increased the osmotic pressure because there was an increase in force required to oppose osmosis in the closed system.
How does NaCl affect the rate of glucose transport?
Predict Question 2: What effect do you think adding Na Cl will have on the glucose transport rate? Your answer: The glucose transport rate will decrease.
What effect did increasing the concentration of sodium chloride from 9 moles to 18 moles have on the rate of diffusion?
The effect of increasing the concentration of sodium chloride from 9mM to 18mM in the left beaker was to _____. Increase the rate of diffusion. Describe the difference between the rate of diffusion seen for sodium and urea. Urea diffused slowly because it is larger than sodium.
What effect does solute concentration have on the rate at which urea diffuses?
Multiple factors affect the rate of diffusion. For example, diffusion rate increases as solute concentration increases, and diffusion rate increases as solute molecular weight decreases. 2. Why do you think the urea was not able to diffuse through the 20 MWCO membrane?
How does concentration affect osmotic pressure?
Osmotic pressure is affected by concentration and temperature. Concentration of solute and temperature each affect the amount of pressure created by the movement of water across a membrane. Higher concentrations and higher temperatures increase osmotic pressure.
How does concentration affect osmosis?
Concentration gradient – The movement of osmosis is affected by the concentration gradient; the lower the concentration of the solute within a solvent, the faster osmosis will occur in that solvent. Light and dark – They are also factors of osmosis; since the brighter the light, the faster osmosis takes place.
What happened when you increase the amount of ATP dispensed with the same concentration of sodium?
What happened when you increased the amount of ATP dispensed with the same concentration of sodium and potassium on either side of the membrane? Your answer: The ions were transported more slowly.
How does sodium affect glucose absorption?
According to this hypothesis, the rate of glucose absorption should decrease markedly if the luminal sodium concentration is markedly reduced, and glucose absorption against a concentration gradient should cease entirely if luminal sodium is lower than intracellular sodium concentration.
What is the effect of concentration on diffusion rate?
If the difference in concentration is higher, then the molecules will go down the concentration gradient faster. If there is not as great of a difference in concentration, the molecules will not move as quickly and the rate of diffusion will decrease.
How does the concentration of a solute affect the diffusion rate?
Increasing the concentration of the solute has no effect on the rate of diffusion. More particles will travel from one side to the other if the concentration is higher. It is analogous to water flowing from a high level to a low level.
What happened when sodium chloride was added as a solute in the left beaker?
What happened when sodium chloride was added as a solute in the left beaker? There was no change in the transport rate of glucose. Sodium was cotransported with the glucose.
What happens to concentration level of a solution if you increase the amount of its solute?
The simplest way to change the concentration would be to change the amount of solute or solvent in the solution. Increasing the solute would increase the concentration. Increasing the solvent would decrease the concentration.
What results from an increase in the solute concentration?
The volume on the side with the solute increases until the number of water molecules on both sides is equal. Increasing the concentration of solute reduces the space available for water molecules, which reduces their numbers. This in turn increases the tendency of the water to flow into that side from the other side.
Why does higher concentration increase the rate of osmosis?
The volume on the side with the solute increases until the number of water molecules on both sides is equal. Increasing the concentration of solute reduces the space available for water molecules, which reduces their numbers. This in turn increases the tendency of the water to flow into that side from the other side.
Does the rate of diffusion of NaCl change with a change in the number of carrier molecules?
Does the diffusion rate of NaCl change with the number of carriers, why? No, because Na+ does not require carriers to cross membrane nor is it required by glucose to cross.
Does salt effect glucose?
Reduce your risk Although salt does not affect blood glucose levels, it's important to limit the amount you eat as part of your diabetes management because too much salt can raise your blood pressure.
How does sodium chloride increase uptake of glucose in the small intestine?
Sodium chloride increases uptake of glucose in the small intestine. Sodium ions and glucose are absorbed by co transport. Co transport happens via a cotransporter protein. Sodium ions are removed via active transport.
Why does increasing concentration increase rate of diffusion?
Diffusion occurs due to the random movement of particles. It usually happens due to a concentration gradient, meaning that molecules move from an area of high concentration to an area of lower concentration.
Why does a higher concentration increase the rate of reaction?
Increasing the concentration of one or more reactants will often increase the rate of reaction. This occurs because a higher concentration of a reactant will lead to more collisions of that reactant in a specific time period.
How does concentration affect a solution?
Increasing the concentration of reactants generally increases the rate of reaction because more of the reacting molecules or ions are present to form the reaction products. This is especially true when concentrations are low and few molecules or ions are reacting.
Should NaCl have an effect on the glucose diffusion explain your answer?
a. No – rate of diffusion is the same with NaCl added – NaCl has no transport proteins to aid in diffusing glucose.
What happened when you increase the amount of ATP dispensed with the same concentration of sodium and potassium on either side of the membrane?
What happened when you increased the amount of ATP dispensed with the same concentration of sodium and potassium on either side of the membrane? Your answer: The ions were transported more slowly.
What happens when you increase concentration?
Increasing the concentration of one or more reactants will often increase the rate of reaction. This occurs because a higher concentration of a reactant will lead to more collisions of that reactant in a specific time period. Physical state of the reactants and surface area.
What will happen to the concentration if you increase the amount of solute in a solution with a pouring additional water into it?
When additional water is added to an aqueous solution, the concentration of that solution decreases. This is because the number of moles of the solute does not change, but the total volume of the solution increases.
What affects concentration of a solution?
When additional water is added to an aqueous solution, the concentration of that solution decreases. This is because the number of moles of the solute does not change, but the total volume of the solution increases.
How does the concentration of salt affect the rate of osmosis?
Salt triggers osmosis by attracting the water and causing it to move toward it, across the membrane. Salt is a solute. When you add water to a solute, it diffuses, spreading out the concentration of salt, creating a solution.
How does NaCl move across a membrane?
Osmosis is the movement of water across a membrane. Salt triggers osmosis by attracting the water and causing it to move toward it, across the membrane. Salt is a solute. When you add water to a solute, it diffuses, spreading out the concentration of salt, creating a solution.
What causes high sodium?
Sodium blood test results that are higher than normal may be a sign of a condition, such as: Dehydration, which may be caused by not drinking enough, diarrhea, or certain medicines called diuretics (water pills) A disorder of the adrenal glands. A kidney disease.
Does sodium chloride increase blood sugar?
Although salt does not affect blood glucose levels, it's important to limit the amount you eat as part of your diabetes management because too much salt can raise your blood pressure.
What affects sodium absorption?
The major part of sodium absorption, i.e. sodium chloride absorption, appeared to be mediated by a process of bulk flow of solution along osmotic pressure gradients. The stimulatory effect of glucose and galactose, even at zero (…) Address requests for reprints to Dr.
