A study was conducted to compare the effects of three levels of digitalis on the levels of calcium in the heart muscles of dogs. Because general level of calcium uptake varies from one animal to another, the tissue for a heart muscle was regarded as a block, and comparisons of the three digitalis levels (treatments) were made within a given animal The calcium uptakes for the three levels of digitalis, A, B, and C, were compared based on the heart...

A channel protein specific for calcium ions was found to have a pore lined with six glutamate residues that participate in coordinating the calcium ion. What would happen to the selectivity of the pore if the Glu residues were mutated to Asp residues? I. Asp residues have shorter side chains than Glu residues. II. Asp residues have longer side chain than Glu residues. III. Mutation to Asp would make the pore wider. IV. Mutation to Asp would make the pore...

Which statements describe the action potential in cardiomyocytes (heart muscle cells)? Depolarization stimulates voltage-gated, slow calcium channels to open. The absolute refractory period can last for about 200 ms. Rapid sodium influx causes the membrane to rapidly depolarize. Repolarization occurs immediately after the initial depolarization.
