Answer the following statements true (T) or false (F)
1. The Nernst Equation is: E = 60 mV log10 ([Xextracellular/Xintracellular]). Given this, the equilibrium potential for a given ion would be increased with an increase in its intracellular concentration. 2. Action potentials are typically also characterized as graded potentials. 3. Saltatory conduction is often studied in large marine invertebrates such as the giant squid. 4. The exposed, unmyelinated gaps between glia on myelinated axons are also sites of voltage-gated Na+ channels.
What is the basic difference between exergonic and endergonic reactions?

C) Exergonic reactions release energy; endergonic reactions absorb it. D) In exergonic reactions, the reactants have less chemical energy than the products; in endergonic reactions, the opposite is true.
