AP Biology Questions and Answers (Graded A) Resting membrane potential depends on which of the following(s)? I. Active transport II. Selective permeability III. Differential distribution of ions across the anxonal membrane All three. The resting potential depends on active transport (the Na+K+ATPase pump) and the selective permeability of the axon membrane to K+ than to Na+, which leads to a differential distribution of ions across the axonal membrane Mitosis The division of the moth...

Adverse effects? - Predominantly a *venodilator*, also some arterial vasodilation - decreases both preload & afterload (stroke volume maintained) -- NO ^cGMP, decreasing intracellular Ca, dephosphorylating myosin light-chain, relaxing vascular smooth muscle -- headaches, flushing, lightheadedness, hypotension, reflex tachycard...

NSC WRITTEN EXAM QUESTIONS. relative refractory period - CORRECT ANSWER period following absolute refractory period, more difficult for the neuron to fire a second AP since membrane is further below threshold (hyperpolarized); more stimulation required Neuron Doctrine (Ramon y Cajal) - CORRECT ANSWER Neurons are discrete, functional units that communicate by contact, not continuity Reticular Theory (Golgi) - CORRECT ANSWER Neurons fuse to form a CONNECTED network/reticulum, making bra...
