195.The excitatory postsynaptic potential (EPSP) is most like which of the following?a.cardiac muscle action potentialb.end-plate potentialc.nerve action potentiald.skeletal muscle action potentiale.smooth muscle action potential_____196.The control mechanism of skeletal muscle contraction is myosin-based because calcium ions bindto troponin which is located on the actin filament._____Next three questionsThe diagram shows a model cell. The cell isequipped with a transporter that utilizes ATP (transporter 1).Transporter 3 mediates facilitative diffusion. The arrows indicatethe directions of movement of the various substances. Use thediagram to answer the next three questions.197.Which of the following best describes transporter 2?YZYZ12_____ 198.Which of the following best describes the intracellular concentrations of the various substances, compared to their extracellular concentrations?XYZX_____ XYZYZ123
X Y0Nerve-Muscle Adair 2016-17199.Which of the following best describes the activity of transporter 3 following treatment with a substance that inhibits transporter 1?a.Decreasesb.Decreases, then increasesc.Increasesd.Increases, then decreasese.No change_____ 200.Two compartments (X and Y) contain different concentrations of NaCl at timezero in the diagram shown. The compartments are separated by a membrane that isnot permeable to NaCl, but is permeable to water. Which of the drawings belowbest describes the volumes of X and Y when the system reaches equilibrium?201.Equilibrium potentials for three unknown ions are shown. Note that ions Qand R are positively charged, and that ion S is negatively charged. Assumethat a cell is permeable to all three ions and has a resting membrane potentialof -90 mV. Which of the following best describes the net movement of thevarious ions across the cell membrane by way of passive diffusion?QRS_____
