4TH SEMESTER URDEN 1. Which of the following structures is the primary pacemaker of the heart? a. Ventricular tissue c. Sinoatrial node b. Atrioventricular node d. Purkinje fibers ANS: C With an intrinsic rate of 60 to 100 beats/min, the sinoatrial node is the primary pacemaker in a healthy heart. The atrioventricular node beats 40 to 60 beats/min. Ventricular tissue must have an electrical impulse to contract. Purkinje fibers beat 15 to 40 beats/min. 2. The atrioventricular (AV) nod...

Study guide test 2 Strategies of nucleotide synthesis: precursors, when is ribose added, how is ribose activated and added, what are first purines and pyrimidines made, how are the various forms of THF made and/or interconverted, regulation of purine synthesis (where are committed steps), how is a balance between AMP and GMP achieved, how do folic acid antagonists impair purine synthesis. • Pyrimidines: base is made before adding the ribose sugar • Purines: ribose is already present  suga...
