- Describe the contribution of each of the following to establishing and maintaining membrane potential: (a) the Na+K+ pump, (b) passive movement of K+ across the membrane, (c) passive movement of Na+ across the membrane, and (d) the large intracellular anions.Choose high or low When the ion binding sites pumps are open to the inside of the cell the pump has a high/low affinity to potassium and a high/low affinity for sodium. When the ion binding sites are open on the outside the pump has a high/low affinity to potassium and a high/low affinity to sodiumWhich of the following is not an excitatory ligand-gated ion channel? NACHR AMPAR ASIC GABA-AR
- Which of the following is the correct statement regarding ion channels? Physical deformation of the membrane cannot open ion channels Ligand-gating means that an ion binds to the channel, which stimulates its opening. If the channel pore was the right size, Na and K could both pass through because they have the same charge A voltage gated Na channel can open to allow Na movement against its electrochemical gradientThe resting potential of most cells is most dependent concentration gradient of: on the transmembrane Chloride Sodium Potassium CalciumWhich of the following statements best describes the features of voltage-gated K+ channels? They consist of 4 subunits, are activated at the same time as voltage-gated Na+ channels, but do not inactivate. They consist of 4 subunits, are activated by depolarisation and close slowly during the refractory period. They have 24 membrane spanning alpha helices, 4 of which have positively charged amino acids which promote a conformational change in the channel following depolarisation. They consist of 4 subunits and are open at rest which causes the resting membrane potential to be close to the K+ equilibrium potential.
- Which of the following statements about voltage gated channels is true? Voltage-gated sodium channels open at a higher (more positive) membrane potential than do potassium-gated channels Voltage-gated sodium channels open at a lower (more negative) membrane potential than do potassium-gated channels Sodium- and postassium-gated channels open at about the same membrane potential, but they have different effects because there are different numbers of the two kinds of channels in neuron cell membranesIn the above diagram, letter C represents: A voltage-gated K+ channel A leaky Na+ channel A leaky K+ channel A voltage-gated Na+ channelClassify each phrase as describing ligand-gated ion channels, voltage-gated ion channels, or both. Ligand-gated ion channels a form of passive transport Voltage-gated ion channels include the acetylcholine receptor change conformation in response to changing membrane potential Answer Bank may participate in an action potential Both change conformation in response to a signal molecule binding
- explain the difference between a ligand gated and voltage gated ion channelBinding of acetylcholine to postsynaptic membranes increases the conductance of Na+ into the cell. It is an example of Group of answer choices active transport voltage-gated channel ligand-gated channel passive transport symporterA cell biologist is performing an experiment using the voltage clamp method in which they are allowed to change the voltage in the membrane potential. They are wanting to record potassium currents and notice that for a certain membrane potential range, the voltage clamp highlights that there is an inward current of potassium. Would these readings make sense?
