What effect does increasing NaCl concentration will have?

Increasing the NaCl will increase the osmotic pressure. because water needs to diffuse to the higher concentration gradient until equilibrium is reached.

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.

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 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 salt concentration affect 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 salt concentration affect osmosis in plant cells?

Osmosis, however, works in both directions. If you put a plant into water with a salt concentration that is higher than the concentration inside its cells, water will move out of the plant to balance out the concentration difference. As a result the plant shrinks and eventually dies.

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.

What is the effect of concentration on diffusion rate?

The greater the difference in concentration, the quicker the rate of diffusion. The higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly. The greater the surface area, the faster the rate of diffusion.

What is the role of Na+ in glucose absorption?

Active glucose absorption is thought to depend on a gradient of sodium ion concentration across the brush border membrane of intestinal epithelial cells. This concept is generally accepted, although its validity has never been adequately evaluated in the human small intestine in vivo.

What variable affects osmotic pressure?

The variable that affects osmotic pressure is Your answer: the concentration of diffusing solutes. Correct answer: the concentration of nondiffusing solutes.

How does the concentration of a solute affect the diffusion rate?

The greater the difference in concentration, the quicker the rate of diffusion.

How does salt concentration affect cell membrane?

Two, the higher the salt concentration the less of a difference it makes how much anionic lipid is present, therefore cells can protect themselves by keeping the internal salt concentration high enough to negate out the anionic lipids but low enough that it is unlikely a large enough gradient can be set-up across the …

How does salt concentration affect osmosis in a potato?

Salt is the key here. Water will move from an area of less salt to more salt (more water to less water), and so when the potato is placed in the saltwater, all the water that is inside the potato (yes, plants have a lot of water inside of them, that's what gives a plant it's structure) moves out by osmosis.

How does NaCl affect osmosis?

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.

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.

Why was there no transport when you dispensed only NaCl Even though ATP was present?

Explain why there was no sodium transport even though ATP was present. This is because there needs to be a gradient present for the sodium potassium pump to fully be active and transport sodium. The sodium potassium pump is a cotransporting protein meaning it needs to have ATP and go up the gradient.

Why does increasing concentration increase rate of diffusion?

The water is the solvent ….The rate of diffusion.

Factor Reason
The concentration gradient The greater the difference in concentration, the quicker the rate of diffusion.
The temperature The higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly.

How does diffusion affect pressure?

Diffusion coefficients are inversely proportional to total pressure or total molar density and are therefore reported by convention at a standard pressure of one atmosphere. Doubling the pressure of a diffusing mixture halves the diffusion coefficient, but the actual rate of diffusion remains unchanged.

How does sodium affect water absorption?

Sodium is absorbed from the gastrointestinal tract, always bringing water along with it. It is the major mineral in plasma, the fluid component of blood, and in the fluids that bathe the body's cells. Without enough sodium, all these fluids would lose their water, causing dehydration, low blood pressure, and death.

What role the transport of sodium plays in glucose transport?

Sodium-glucose cotransporter (SGLT) activity mediates apical sodium and glucose transport across cell membranes. Cotransport is driven by active sodium extrusion by the basolateral sodium/potassium-ATPase, thus facilitating glucose uptake against an intracellular up-hill gradient.

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.

Does salt increase osmotic pressure?

7. The increase in swelling in salt solutions is due to an increase in osmotic pressure.

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.

What concentration of NaCl is isotonic to the potato cells?

In the osmosis potato lab experiment, 0.2 M solution concentration of NaCl showed to be isotonic. The 0.4 M solution concentrations of glucose and sucrose also showed to be isotonic.

How does salt affect osmosis in plants?

More on the osmotic effects of salt Due to osmosis, water naturally moves from an area containing less salt to an area containing more salt. The more salt that accumulates in the soil from irrigation and natural occurrence, the more energy that a plant must expend to draw water from the soil into its roots.

How does salt affect osmotic pressure?

loss of electrolytes (salt), the osmotic pressure of the extracellular fluids becomes higher than in the cells. Since water passes from a region of lower to a region of higher osmotic pressure, water flows out of the cells into the extracellular fluid, tending to lower its osmotic pressure and increase…

How does salt concentration affect the rate of osmosis?

Osmosis, however, works in both directions. If you put a plant into water with a salt concentration that is higher than the concentration inside its cells, water will move out of the plant to balance out the concentration difference.

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 happens 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 solute concentration affect diffusion?

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.
