The sodium-potassium pump within living cells requires energy to move ions across the cell membrane to maintain homeostasis. how is this energy supplied? a when adenine is removed from adenosine triphosphate (atp), a large amount of energy is produced. b when two adenosine triphosphate (atp) molecules are fused together, a large amount of energy is produced. c when a phosphate group is removed from adenosine triphosphate (atp), a large amount of energy is produced. d when the sugar and phosphate groups of adenosine triphosphate (atp) are fused together, a large amount of energy is produced.

Match the following terms describing electrical events with the correct phases of the cardiac cycle. the ventricular muscle cells depolarize at the start of this phase. during this phase, na+ entry through the funny channels causes the pacemaker potential of sa nodal cells to gradually become less negative until it reaches threshold. the ventricular muscle cells repolarize right before this phase. the cytosolic concentration of calcium in the contractile cells of the ventricle is highest during this phase. a. isovolumetric relaxation b. ventricular ejection c. isovolumetric contraction d. ventricular filling
