What do you think will result from these experimental conditions Na+ will be maximally transported?
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 does increasing the pore size increases the filtration rate?
The increase in pore size increased the filtration rate because more filtrate was allowed to go through the membrane. An analogy to this is if you imagine a wall that initially had a small gate that allowed only some people through, making the rate of the transport of people slow.
Which of the following results in an increase in the filtration rate?
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.
Why increasing the pore size increases the filtration rate?

Which of the following resulted in an increase in filtration rate?
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.
How does size affect osmosis?
Factors Affecting the Rate of Osmosis Surface Area – The larger the surface area, the more space for the molecules to move easily across; the smaller the area, the more restricted the movements of the molecules and the slower the movement.
What was the effect on active transport of adding more sodium potassium pumps to the cell?
What was the effect of adding more Na -K pumps to the simulated cell? You correctly answered: Transport of the ions was faster.
How does pore size affect the rate of diffusion?
Small-sized solute molecules can diffuse easily as compared to large-sized molecules. … Therefore larger molecules diffuse slower.
What increases glomerular filtration rate?
increased blood pressure Increased blood volume and increased blood pressure will increase GFR. Constriction in the afferent arterioles going into the glomerulus and dilation of the efferent arterioles coming out of the glomerulus will decrease GFR.
What factors affect glomerular filtration rate?
We analyzed the factors that are thought to affect changes in GFR, such as age, sex, body mass index (BMI), preoperative GFR, preoperative creatinine level, operated side, presence of diabetes mellitus (DM), presence of hypertension (HTN), and duration of follow-up.
Does pore size affect osmosis?
The influence of pore density and solute size on osmosis is independent of pore size and solute concentration.
How can you increase the rate of osmosis?
Temperature – The higher the temperature, the faster the water molecules move across the semi permeable membrane. Surface Area – The larger the surface area, the more space for the molecules to move easily across; the smaller the area, the more restricted the movements of the molecules and the slower the movement.
What increases the rate of sodium-potassium transport?
Internal potassium stimulates the sodium-potassium pump by increasing cell ATP concentration.
Which of the following will increase the rate of diffusion?
Temperature: Higher temperatures increase the energy and therefore the movement of the molecules, increasing the rate of diffusion. Lower temperatures decrease the energy of the molecules, thus decreasing the rate of diffusion. Solvent density: As the density of a solvent increases, the rate of diffusion decreases.
What increases glomerular filtration rate quizlet?
The glomerular filtration rate increases, due to the increased blood flow into the glomerulus.
What factors affect filtration rate?

What factors affect glomerular filtration rate quizlet?
The factors which determine GFR are the net effective filtration pressure, permeability characteristics of the glomerular membrane and its surface area.
How can I improve glomerular filtration rate?
Avoid processed foods and choose fresh fruits and vegetables instead. Follow a low-salt diet. Salt should be limited especially if you have high blood pressure, protein in your urine, or swelling, or difficulty breathing. Eating less than 2000 mg a day of sodium is recommended.
How does particle size affect rate of osmosis?
In addition, the size of the particles can affect the rate of diffusion through the membrane smaller particles are able to pass through the membrane quicker than larger molecules. Lastly, the size of concentration gradient can greatly affect the rate of osmosis.
How does particle size affect the rate of diffusion?
Mass of Particle: Heavier particles will move more slowly and so will have a slower rate of diffusion. Smaller particles on the other hand will diffuse faster because they can move faster.
Why increasing the pore size increased the filtration rate?
The increase in pore size increased the filtration rate because more filtrate was allowed to go through the membrane. An analogy to this is if you imagine a wall that initially had a small gate that allowed only some people through, making the rate of the transport of people slow.
Which of the following result in an increase in the filtration rate?
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.
How does the size and charge affect the rate of diffusion?
It takes more energy to move a large object than it foe to move a small one, so small molecules diffuse more quickly than larger ones.
What three factors affect the rate of diffusion and how do they affect the rate?
Diffusion of substances plays an important role in cellular transport in plants. The rate of diffusion is affected by the concentration gradient, membrane permeability, temperature, and pressure. Diffusion takes place as long as there is a difference between the concentrations of a substance across a barrier.
What causes an increase in the glomerular filtration rate?
An increase in renal arterial pressure (or renal blood flow) causes an increase in GFR. A reduction in renal arterial pressure (or renal blood flow) will have the opposite effect (1).
How do you increase filtration rate?
Some studies have shown that GFR may increase over time in people at all stages of kidney disease by: Controlling blood pressure. You can manage high blood pressure through exercise, diet, stress reduction, and limiting alcohol, among other lifestyle choices. Making sure you're not deficient in vitamin D.
How does particle size affect filtration rate?
Particle Size of Solids Generally the large the particle size, the higher the filtration rate in Kg/m2/h and the lower the cake moisture.
