What is the effect of increasing NaCl concentration have on osmotic pressure?
Increasing the NaCl increased the pressure. When the NaCl concentration increase from 5 to 10, the pressure increased from 170 to 340. The pressure increased because water diffuses to a higher concentration gradient, so the pressure will increase.

Why does increasing the pore size increases the filtration rate?
Pore size increased filtration rate because, as pore size increases, resistance to flow decreases. Many analogies are possible: electricity flows more quickly down a wider wire; sand falls more quickly through a sieve with bigger openings; etc. 2.

How did the diffusion rate change when you increased the number of protein carriers?
Answer and Explanation: Facilitated diffusion can involve the use of carrier proteins to transport the molecule across the lipid bilayer. If the number of carrier proteins was increased, then more molecules can be transported across the membrane, thus increasing the concentration of the molecule inside the cell.

Does membrane pore size affect simple diffusion?
While a porous membrane will prevent any molecule larger than the largest pore from diffusing through, it also hinders the diffusion of molecules smaller than this pore size.

How can you increase the filtration rate through living membranes?
Your Answer: In a living membrane, you can increase the filtration rate through 1) increasing the hydrostatic pressure or decreasing the osmotic pressure on one side of the membrane, 2) increasing the size of the pores, and 3) increasing the osmotic pressure or decreasing the hydrostatic pressure on the other side of …

What is the effect of NaCl concentration on bacterial growth?
Bacterial growth was enhanced by 1–2% (w/v) of added NaCl, while NaCl concentrations above 3% (w/v) had a clear inhibitory effect.

What happened to the rate of diffusion when you increase the NaCl solute concentration?
We can see that as the concentration of the NaCl was higher, the diffusion rate increased. That is because the diffusion rate is affected by the concentration gradient, the grater the difference between two areas, the greater will be the rate of diffusion.

How does the number of transport proteins affects the rate of facilitated diffusion?
Answer and Explanation: The number of transport proteins affects the rate of facilitated diffusion as more proteins are present, more sites are available. This means the higher the diffusion capacity and diffusion will be faster.

What are 3 factors that affect the rate of facilitated diffusion?
Facilitated diffusion is a natural movement in which specific structural systems of biomembranes interact with specialised solute molecules allowing them to pass the membrane faster. The factors affecting the rate of facilitated diffusion include temperature, concentration gradient, selectivity, and saturation.

What effect will increasing the NaCl concentration have?
Increasing the NaCl concentration from 0.7% NaCl to 23.4% NaCl resulted in a reduction in the impedance and an increase in power (mean watts of 1.4-3.25 W).

What is the osmotic pressure of NaCl concentration?
For seawater, for example, where the NaCl concentration ranges from 3.0% to 4.0% (or approximately 30–40 g/L or 0.51–0.68 mol/L), the osmotic pressure is between 25 and 33 bar for a temperature of 25°C.

Does salt increase or decrease osmotic pressure?
The increase in osmotic pressure caused by the salt is reversible on removal of the salt. 6. The observed osmotic pressure is much greater than the osmotic pressure calculated from the Donnan equilibrium except in the case of AlCl3, where the calculated and observed pressures agree quite closely.

How does salt affect osmotic pressure?
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.
