- describe what the resting membrane potential of a cell is. What is the resting membrane potential of neurons (give units)? What are the two factors that generate the resting membrane potential? Think of scenarios that change the factors that generate the resting membrane potential and how that would change the overall resting membrane potential.The presence of an electrical gradient is responsible for both the resting membrane potential and the action potential in the neuron.a. In this case who is responsible for maintaining the electric gradient to produce a potential for the resting membrane?b. Explain what is meant by an electrical gradient in the context of a cell (neuron)!Diagram an Action potential: an action potential graph showing the 4 steps of an action potential AND what is happening to the sodium voltage-gated channels and voltage-gated potassium channels at each step
- You observe that a neuron treated with a metabolic inhibitor which prevents ATP generation still can generate action potentials even when the cell has little ATP, but the neuron eventually loses the ability to generate action potentials. What does this tell you about the direct mechanism for regenerating the resting potential after an action potential?Draw a simple schematic of a neuron and label its parts. Where does “information” usually go in and through which structure is it passed on? Where is the action potential generated?You find a neuron whose resting potential is -90mV. Which of the following are likely to be true? (select all that apply) Voltage-gated sodium channels are closed The neuron is fully permeable to sodium The neuron is permeable to potassium The neuron is hyperpolarized
- describe how the membrane potential varies over time AND distance as a graded potential move across the cell body of a neuron. Describe the movement of ions within the cell body as the graded potential moves away from the stimulusExperimenters injected bark scorpion venom into mouse neurons and measured how many action potentials were generated after the venom was introduced. Is it possible that the venom could be affecting the activity of a voltage-gated potassium channel?
