Which is an example of filtration quizlet?
Water and solutes are forced through pores of a body membrane by the hydrostatic pressure of blood (i.e. blood pressure). e. Example – blood being filtered through the capillaries (neprons) of the kidney.
Which of the following are necessary for diffusion to take place?
These are the conditions required for diffusion – concentration gradient for molecules to move from higher to lower concentration, semi permeable membrane. Additionally, the size of molecules should be small to easily pass through the membrane.
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.
Which of the following is a driving force for the sodium-potassium pump?
The sodium-potassium pump carries out a form of active transport—that is, its pumping of ions against their gradients requires the addition of energy from an outside source. That source is adenosine triphosphate (ATP), the principal energy-carrying molecule of the cell.
What is filtration quizlet?
Filtration is the process of eliminating undesirable low-energy x-ray photons by the insertion of absorbing materials into the primary beam.
How does filtration work quizlet?
is the separation of an insoluble solid from a fluid by means of a porous medium which retains the solid but allows the fluid to pass.
What is not necessary for diffusion?
Both diffusion and osmosis are passive transport processes, which means they do not require any input of extra energy to occur. In both diffusion and osmosis, particles move from an area of higher concentration to one of lower concentration.
What are conditions necessary for osmosis?
The process of osmosis may occur under the following conditions: There should have two solutions. One concentrated and other dilute. A semi-permeable membrane should separate the two solutions of different concentration.
What are the driving forces for filtration in the nephron?
The force of hydrostatic pressure in the glomerulus (the force of pressure exerted from the pressure of the blood vessel itself) is the driving force that pushes filtrate out of the capillaries and into the slits in the nephron.
Which of the following factor reduces the rate of filtration?
Pressure. The rate of filtration at any instant of time is directly proportional to the pressure difference across the bed. In cake filtration, deposition of solids over a finite period increases the bed depth. If, therefore, the pressure remains constant, the rate of filtration will fall.
Which of the following is required for the sodium-potassium pump to transport potassium ions into an animal cell?
Question 45 Transport of potassium ions into an animal cell by the sodium-potassium pump requires high intracellular concentrations of sodium: high intracellular concentrations of potassium .
How does sodium-potassium pump work?
The sodium-potassium pump uses active transport to move molecules from a high concentration to a low concentration. The sodium-potassium pump moves sodium ions out of and potassium ions into the cell. This pump is powered by ATP. For each ATP that is broken down, 3 sodium ions move out and 2 potassium ions move in.
What is the purpose of the filter or filtration quizlet?
Filtration removes a potion of the useful beam. The primary purpose of the collimator is filtration. Filtration that occurs outside the tube and housing is considered to be added filtration.
What is the process of diffusion and filtration?
0:402:12Osmosis Diffusion Filtration – YouTubeYouTube
What happened in the process of filtration?
filtration, the process in which solid particles in a liquid or gaseous fluid are removed by the use of a filter medium that permits the fluid to pass through but retains the solid particles. Either the clarified fluid or the solid particles removed from the fluid may be the desired product.
What filtration occurs quizlet?
Filtration occurs as pressure forces water and solutes across the walls of the glomerular capillaries and into the capsular space. Filtration is based on particle size. Solute molecules small enough to pass the filtration membrane are carried by the surrounding water molecules.
Does filtration require energy?
Filtration is the movement of water and solute molecules down the concentration gradient, e.g. in the kidneys, and osmosis is the diffusion of water molecules across a selectively permeable membrane. None of these processes require energy.
Is energy required for osmosis?
Both diffusion and osmosis are passive transport processes, which means they do not require any input of extra energy to occur. In both diffusion and osmosis, particles move from an area of higher concentration to one of lower concentration.
Which of the following is not necessary for osmosis to take place?
So the correct answer is 'Gravitational potential'.
Does osmosis require energy?
Both diffusion and osmosis are passive transport processes, which means they do not require any input of extra energy to occur. In both diffusion and osmosis, particles move from an area of higher concentration to one of lower concentration.
Which of the following forces drives filtration?
Which of the following forces drives filtration? *Glomerular hydrostatic pressure (GHP) is the force with which blood pushes on the walls of glomerular capillaries and it drives filtration.
What is filtering filtration?
Filtration is the process of separating suspended solid matter from a liquid, by causing the latter to pass through the pores of some substance, called a filter. The liquid which has passed through the filter is called the filtrate.

Which of the following is required for the sodium-potassium pump to transport potassium ions into an animal cell quizlet?
Which of the following is required for the sodium-potassium pump to transport potassium ions into an animal cell? ATP is required to help move 3 Na ions out of the cell and 2 K ions into the cell.
Which type of membrane protein is involved in the sodium-potassium pump?
active transport membrane protein/transmembrane ATPase The sodium-potassium pump is an example of an active transport membrane protein/transmembrane ATPase. Using the energy from ATP, the sodium-potassium moves three sodium ions out of the cell and brings two potassium ions into the cell.
Which of the following are required for the sodium-potassium pump in cells to work?
Which of the following are required for the sodium potassium pump in cells to work? ATP and Carrier proteins.
What is sodium potassium?
Potassium and sodium are electrolytes that help your body maintain fluid and blood volume so it can function normally. However, consuming too little potassium and too much sodium can raise your blood pressure. 1. Though the words “salt” and “sodium” are often used interchangeably, they do not mean the same thing.
What is the main purpose of filtration?
Filtration is used to separate particles and fluid in a suspension, where the fluid can be a liquid, a gas or a supercritical fluid. Depending on the application, either one or both of the components may be isolated.
Which of the following is type of filtration?
Answer: Filters can be active or passive, and the four main types of filters are low-pass, high-pass, band-pass, and notch/band-reject (though there are also all-pass filters).
