Calcium chloride typically increases sodium chloride rejection in a membrane filter. This is because calcium chloride can create a more concentrated solution on one side of the membrane, leading to an increased osmotic pressure that enhances the rejection of sodium chloride during filtration.

Which is true of drugs that decrease membrane permeability to sodium ions?
It would decrease the probability of generating a nerve impulse. When a neuron is activiated by a threshold stimulus, the membrane briefly becomes more permeable to sodium. If the permeability is decreased, it will be more difficult for the sodium ions to rush into the cell.
What happens if the permeability of a resting axon to sodium ion increases?
inward movement of sodium will increase and the membrane will depolarize.
What is membrane permeability?
Membrane permeability refers to the ability of a membrane to allow substances to pass through it. This can vary depending on the size and properties of the molecules trying to cross the membrane. Factors such as lipid composition, protein channels, and transporters on the membrane impact its permeability.
What factors affect the diffusion of water?
One of the factors that affect the diffusion of water through a membrane by osmosis is the permeability of the membrane. The amount of water on each side of the membrane may also have an effect on water's diffusion. Water will diffuse to the side with little water to even out the concentration.
What effect does the leaking of potassium across the membrane have on the membrane potential of Kevin's neurons?
It makes the inside of the neurons more negative.
Does the cristae increase or decrease the surface area of the inner membrane?
Cristae increases the surface area of the interior membrane of the mitocondria.
What type of membrane protein responsible for rejection in tissue transplants?
Major histocompatibility complex (MHC) proteins, specifically MHC class I and II, are responsible for initiating an immune response against foreign tissues in tissue transplants. These proteins present antigens to T cells, triggering the immune system to recognize and reject the transplant as a foreign entity.
What can increase or decrease the rate of diffusion?
increasing the surface area of the membrane
Would a substance that decreases membrane permeability to sodium increase or decrease the generating of a nerve impulse?
A substance that decreases membrane permeability to sodium would decrease the generation of a nerve impulse. This is because sodium ions play a crucial role in depolarizing the membrane and initiating nerve impulses. By reducing sodium influx into the cell, the ability of the neuron to generate an action potential would be diminished.
What happens if the surface area of the respiratory membrane decrease in gas exchange?
A decrease in the surface area of the respiratory membrane will result in a decrease in gas exchange.
WOULD A SUBSTANCE THAT DECREASES MEMBRANE PROBABILITY TO SODIUM INCREASE OR DECREASE THE PROBABILITY OF GENERATING A NERVE IMPULSE?
It would decrease the probability of generating a nerve impulse. When a neuron is activiated by a threshold stimulus, the membrane briefly becomes more permeable to sodium. If the permeability is decreased, it will be more difficult for the sodium ions to rush into the cell.
What is the effect of glycerol on a cell membrane?
Glycerol can act as a cryoprotectant, stabilizing cell membranes during freezing and thawing processes. It can also disrupt hydrogen bonding within the lipid bilayer, potentially causing leakage of cellular contents and altering membrane structure and function. Additionally, glycerol can help maintain membrane fluidity by interacting with phospholipid molecules.
Drugs that decrease membrane permeability to sodium are used as what?
Drugs that decrease membrane permeability to sodium are used as local anesthetics. These drugs block the sodium channels and prevent NA+ from entering the cell. NA+ influx is important to dipolarize the membrane.
What would a substance that decreases membrane premeability to sodium increase or decrease the probability of generating a nerve impulse?
A substance that decreases membrane permeability to sodium would decrease the probability of generating a nerve impulse. This is because sodium ions play a critical role in the depolarization phase of an action potential by entering the cell, so if their permeability is reduced, it hinders the ability to reach the threshold for generating an impulse.
What is the result of damage to the thlaykoid membrane in a plant?
A decrease in glucose production
What happens if you put a balloon in the microwave?
It would increase in volume. According to Charles' Law, as you increase temperature the volume will increase as well. So if you would put it in a freezer, it would shrink because as you decrease temperature, you decrease volume.
What results in a defect in membrane proteins that normally function in chloride ion transport?
Defects in membrane proteins that normally function in chloride ion transport can result from mutations in genes coding for those proteins. These mutations can lead to altered protein structure or function, affecting the ability of the protein to transport chloride ions across the membrane correctly. This can result in conditions such as cystic fibrosis, where mutations in the CFTR gene lead to defective chloride ion transport.
