Question 1
When sodium channels open during an action potential, the opening is caused by
◦ presence of positive charge.
◦ binding of potassium ions.
◦ presence of calcium.
◦ binding of sodium ions.
Question 2
The primary problem in hyperkalemia is that
◦ neurons respond too quickly to smaller graded potentials.
◦ neurons are easier to excite because their resting potential is closer to threshold and neurons respond too quickly to smaller graded potentials.
◦ neurons are harder to excite because their resting potential is hyperpolarized and neurons respond too quickly to smaller graded potentials.
◦ neurons are harder to excite because their resting potential is hyperpolarized.
◦ neurons are easier to excite because their resting potential is closer to threshold.
