Question
Chapter 13, Problem 8P
Interpretation Introduction
Interpretation:
The difference between ligand-gated channels and voltage-gated channels needs to be explained.
Concept introduction:
Allowing the ions to pass through the membrane with the response of ligand is called ligand-gated channels.
Activating the ion channels by the electrical membrane potential is voltage-gated channels.

channels.
Please ASAP. Thanku.
What is the effect of increasing the activity of HCN (Ih) channels on action potential firing rate?
Neurons
a. How does the neuron re-establish its resting membrane potential after an action potential?
-Sodium (Na+) gated channels close
-Sodium (Na+) gated channels open
-Potassium (K+) and sodium (Na+) gated channels close
-Sodium/ potassium pumps (Na+/K+ pumps) exchange ions
b.Which of the ion channels utilizes a passive transport system (in other words, do not require ATP)? Mark all that apply.
-K+ leak channels
-K+ channels (gates)
-Na+ leak channels
-Na+ channels (gates)
-Na+/K+ pumps
c.The absolute refractory period occurs when the neuron is undergoing the action potential and implies it cannot be further stimulated.
True or False
d. After an action potential, as the neuron repolarizes, the resting membrane potential is immediately re-established
True or False
e.Match the type of gate or process with its overall effect on the neuron
So Match each term with the best-fit description.
Terms:
Na+/K+ pump
K+ voltage gate
Resting membrane potential
Hyperpolarization
Na+ voltage gate…
