Which of the following resulted in an increase in the filtration rate? Both increasing the pressure above the beaker and increasing the concentration of solutes are correct. Both increasing the pore size and increasing the pressure above the beaker are correct.
What would happen related to osmotic pressure if you increased the albumin concentration in the left beaker using any membrane?
Osmosis: What would happen if you doubled the albumin concentration in the left beaker using any membrane? The osmotic pressure would be greater, so more water will cross the membrane.
What happens to the rate of facilitated diffusion when the number of carrier proteins increases?
Carrier proteins increase the rate of diffusion by allowing more solute to enter the cell. Facilitated diffusion, however, approaches a maximum rate as the carrier proteins become saturated with solute.
What effect do you think increasing the 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 was the effect of adding more Na+ pumps to the simulated cell?
What was the effect of adding more Na+ -K+ pumps to the simulated cell? There was no change in the transport rate because glucose is transported independently.
Why did increasing the pressure increase the filtration rate but not the concentration of solutes How well did the results compare with your prediction?
Pressure increased the filtration rate but not the concentration of solutes because it increased the hydrostatic pressure gradient that exists. The solute concentration gradient didn’t change from Trial 3 to 4 for 200 MWCO, however the pressure gradient increase allowed for the increased rate of filtration.
What effect does sodium chloride have on glucose transport?
What effect do you think adding Na+Cl- will have on the glucose transport rate? Increasing the NaCl will increase the osmotic pressure. because water needs to diffuse to the higher concentration gradient until equilibrium is reached.
What effect will NaCl have on glucose transport rate?
Predict Question 2: What effect do you think adding Na+ Cl- will have on the glucose transport rate? Your answer : c. There will be no change in the glucose transport rate.
What will happen if you increase the pressure above the beaker?
What will happen if you increase the pressure above the beaker (the driving pressure)? The filtration rate will increase. The solutes were all too large to pass through.
What happens to osmotic pressure with increasing solute concentration?
The osmotic pressure driving water across an impermeable barrier increases with the difference in solute concentrations on either side of the barrier. In a solution with more than one solute, sum the concentrations of all the solutes to determine the total solute concentration.
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.
What affects the rate of diffusion?
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.
When looking at your data from the effect of concentration on the rate of diffusion lab what occured to the rate of diffusion as time elapsed?
the rate of diffusion increases. In a semi-solid, if the concentration of the solute is increased, the rate of diffusion increases. Assuming that all of the following substances are permeable across a selectively permeable membrane, which of the following molecules would you predict to move fastest across the membrane?
Why does increasing pore size increase filtration?
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.
What will happen if you increase the pressure above the beaker the driving pressure which represents blood pressure in the human kidney )?
Terms in this set (15)
What will happen if you increase the pressure above the beaker (the driving pressure)? The filtration rate will increase. The solutes were all too large to pass through.
What do you think will result from these experimental conditions Na+ will be maximally?
Predict Question 1: What do you think will result from these experimental conditions? Your answer: Na will be maximally transported. sodium or potassium? Your answer: No, it will not affect the transport of either ion.
Why did the sodium transport stop?
Why did the sodium transport stop before the transport was completed? The ATP was depleted. Why was the equilibrium for the solutes reached earlier? There were more pumps for transport.
What is the source of energy used to power the sodium potassium pump?
The source of energy used to power the sodium potassium is the breakdown of ATP. The binding and releasing of sodium or potassium ion are due to conformational changes in the protein. Active transport moves substances from an area of high concentration to an area of low concentration of the substance.
