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 do you think there is no pressure change?
Why do you think there was no pressure change? There is no net movement of water because the solute concentrations are the same.
What effect does increasing NaCl concentration have on osmotic pressure?
Increasing the NaCl concentration increased the osmotic pressure because there was an increase in force required to oppose osmosis in the closed system.
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.
Do you think the addition of glucose carriers will affect the transport of sodium or potassium?
The addition of glucose carriers had no effect on sodium or potassium transport because the potassium and sodium ions move through primary active transport. Glucose carriers move glucose molecules across the membrane so the sodium and potassium ions will not be affected.
Why do you think the urea was not able to diffuse through the 20 Mwco membrane?
The urea molecules were not able to diffuse through the 20 MWCO membrane because they were too large to fit through the pores.
Which of the following would result in no change in osmotic pressure?
Which of the following would result in NO change in osmotic pressure across a membrane? The solutes can diffuse through the pores and the concentration of solutes is the same on both sides of the membrane.
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.
How does pressure affect osmosis?
Factors Affecting the Rate of Osmosis Pressure – The more the pressure, the faster the molecules will move for they are being pushed faster across a low concentration.
How does osmotic pressure affect osmosis?
Osmotic pressure is the pressure required to stop water from diffusing through a membrane by osmosis. It is determined by the concentration of the solute. Water diffuses into the area of higher concentration from the area of lower concentration.
What happens when pressure is exerted on a closed vessel filled with water?
The fluid pressure applied to a fluid in a closed vessel is transmitted to all parts at the same pressure value as that applied (Pascal's law). Figure 3.3. Hydraulic press. So this device can create the large force F2 from the small force F1.
Do you think the addition of glucose carriers will affect the transport of sodium or potassium quizlet?
The addition of glucose carriers had no effect on sodium or potassium transport because the potassium and sodium ions move through primary active transport. Glucose carriers move glucose molecules across the membrane so the sodium and potassium ions will not be affected.
What effect do you think increasing the number of protein carriers will have on the glucose?
What effect do you think increasing the number of protein carriers will have on the glucose transport rate? Increasing the number of protein carriers will increase the glucose transport rate.
Why do you think the urea was not able to diffuse through the 20 Mwco membrane How well did the results Comparewith your prediction?
The urea molecules were not able to diffuse through the 20 MWCO membrane because they were too large to fit through the pores.
Which of the following will be able to diffuse through the 200 Mwco Oh membrane?
glucose only Which of the following will be able to diffuse through the 200 MWCO membrane? Your answer: glucose only.
Which of the following conditions would cause an increase in the glomerular filtration rate?
Key Points. Glomerular filtration is occurs due to the pressure gradient in the glomerulus. Increased blood volume and increased blood pressure will increase GFR.
What conditions increase glomerular filtration pressure quizlet?
The stretching of the afferent arteriole walls leads to increased constriction of the afferent arteriole. Activation of the macula densa cells leads to an increased glomerular filtration rate. Increased glomerular filtration rate leads to paracrine secretion from the macula densa.
What is osmosis pressure in biology?
Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane. It is also defined as the measure of the tendency of a solution to take in a pure solvent by osmosis.
How does osmotic pressure influence the direction and strength of osmosis?
Factors Affecting the Rate of Osmosis Pressure – The more the pressure, the faster the molecules will move for they are being pushed faster across a low concentration.
What affects 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.
What is osmotic pressure answer?
Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of water across a semipermeable membrane. It is also defined as the measure of the tendency of a solution to take in water by osmosis.
What is pressure short answer?
Pressure is defined as the physical force exerted on an object. The force applied is perpendicular to the surface of objects per unit area. The basic formula for pressure is F/A (Force per unit area). Unit of pressure is Pascals (Pa). Types of Pressures are Absolute, Atmospheric, Differential, and Gauge Pressure.
How is pressure affected by force?
Pressure equals force divided by area (P=FA P = F A ). The equation shows that pressure is directly proportional to force, but inversely proportional to area. At a constant area, pressure increases as the magnitude of the force applied also increases.
Do you think the addition of glucose carriers will affect the transport of sodium and potassium?
The addition of glucose carriers had no effect on sodium or potassium transport because the potassium and sodium ions move through primary active transport. Glucose carriers move glucose molecules across the membrane so the sodium and potassium ions will not be affected.
Do you think the addition of glucose will affect the transport of sodium or potassium?
Predict Question 2: Do you think the addition of glucose carriers will affect the transport of sodium or potassium? Your answer: No, it will not affect the transport of either ion.
Why do you think the urea was not able to diffuse through the 20 Mwco?
The urea molecules were not able to diffuse through the 20 MWCO membrane because they were too large to fit through the pores.
Which of the following will be able to diffuse through the 200 Mwco membrane?
glucose only Which of the following will be able to diffuse through the 200 MWCO membrane? Your answer: glucose only.
Why do you think the urea was not able to diffuse through the 20 MWCO membrane?
The urea molecules were not able to diffuse through the 20 MWCO membrane because they were too large to fit through the pores.
How does MWCO affect filtrate concentration explain the relationship?
Your Answer: The MWCO had no affect on the filtrate concentration. As long the MWCO is high enough to allow both the solute and water to pass through, water would pass through the pores at the same rate as the solutes, and thus the concentration of the filtrate would not change.
What are the pressures that oppose glomerular hydrostatic pressure?
Glomerular filtration occurs when glomerular hydrostatic pressure exceeds the luminal hydrostatic pressure of Bowman's capsule. There is also an opposing force, the osmotic pressure, which is typically higher in the glomerular capillary. Figure 1.
