Draw a typical action potential (correctly label axis) and explain in words the roles of ion channels in generating the different phases of the action potential. (Extra credit: How would opening voltage gated calcium channels upon depolarization affect the shape of the action potential if they have a relatively slow inactivation rate?)

Expert Solution
Step 1

An action potential (AP) occurs when the membrane potential of a particular cell position rises rapidly and falls:[1] this depolarization causes the neighboring locations to depolarize similarly. Action potentials occur in many types of animal cells, called excitable cells, including neurons, muscle cells, endocrine cells, and certain plant cells.
