Question textRefer to the action potential diagram below. For each question, select the answer or answers that best complete the statement relating to the phases of the action potential and the movement of ions across the membrane. The rising phase at label A is best described as Answer 1 Question 2[select: , resting membrane potential, depolarisation, repolarisation, hyperpolarisation], caused primarily by Answer 2 Question 2[select: , K+ exiting the neuron, Na+ exiting the neuron, Ca2+ exiting the neuron, Cl- entering the neuron, Na+ entering the neuron]. The falling phase at label B is caused by Answer 3 Question 2[select: , Na+ entering the neuron, K+ exiting the neuron, protein leakage, Ca2+ entering the neuron], leading to Answer 4 Question 2[select: , threshold, hyperpolarisation, summation, repolarisation, depolarisation]. The undershoot at label C occurs because Answer 5 Question 2[select: , Cl- enters through ligand channels, threshold is lowered, K+ channels close slowly, Na+ channels reopen rapidly], resulting in Answer 6 Question 2[select: , resting membrane potential, depolarisation, threshold, plateau potential, hyperpolarisation]. The neuron begins from a Answer 7 Question 2[select: , threshold potential, resting membrane potential, peak overshoot, graded depolarisation] of approximately Answer 8 Question 2[select: , 0 mV, +70mV, -55 mV, +30 mV, -70 mV].
Use the picture of the action potential in a specialized cell and letters to select the best choice to match the description that follows. Answers may be used more than once. 1: Voltage gated calcium channels are open 2: Voltage gated potassium channels are open 3: The prepotential
