Acetylcholine is necessary for the depolarization of skeletal muscle cells. Which of thefollowing statements concerning acetylcholine action is true.O acetylcholine is released in quanta from the sarcolemma membrane by exocytosisO acetylcholine is released in quanta from the postsynaptic membrane by exocytosisO acetylcholine enters the caveoli to depolarize the sarcolemmaacetylcholine enters clathrin -coated vesiclec prior to its degradation byO acetylcholine attaches to transmitter-gated ion channels of the sarcolemma. During an action potential, depolarization occurs because:Channels for sodium ions in the cell membrane open and sodium flows into the cellO Both channels for sodium and potassium are closedO Channels for potassium ions in the cell membrane open and potassium leaves he cellSodium potassium pump retums sodium to the outside of the cell and potassium tothe insideStroke occurs whena blood clot enters the cerebral ciruculatin, blocking an artery and causing the deathof brain tissuethe pacemaker become defective, producing an irregular heartbeatO a blood clot enters and blocks one of the coronary arteriesa blood clot dislodges from a vein and moves into the lung, where it blocks apulmonary arterythe walls of an artery accumulate deposits and loss their flexibility and elasticityErythrocyte productionO is stimulated by erythropoietin.requires folate, B12, and iron.is stimulated by low 02 levels in the blood.occurs in red bone marrow.all of these
