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 molecules, substances, etc. to pass through the membrane. For example, the cell membrane is referred to as 'semi-permeable' because it allows some molecules (such as water) to enter, and stops other molecules (such as sodium ions) from passing through the membrane. If these want to get into the cell, they must then rely on proteins in the cell membrane to let them in.
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.
What happens when you open the sodium channels in the membrane of a neuron?
When this occurs, the membranes potenial drops, as potassium and sodium diffuse with their gradient.
Would a substance that decreases membrane permeability to sodium increase or decrease the generating of a nerve impulse?
Decrease
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?
what type of membrane protein is responsible for rejection in tissue transplant
What can increase or decrease the rate of diffusion?
increasing the surface area of the membrane
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.
What would a substance that decreases membrane premeability to sodium increase or decrease the probability of generating a nerve impulse?
Allowing more sodium ions into a nerve generates a nerve impulse. so decreasing membrane permeability of sodium would decrease the probability of generating a nerve impulse.
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?
It interact with membrane to increase stiffness
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 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 is the most likely result of the damage to the thlaykoid membrane in the plants?
Such plant cells will not be able to perform photosynthesis
