Chapter 42, Problem 1DA
Data analysis Draw the resulting potentials for all possible combinations of E1, E2, and I.
Expert Solution & Answer
Summary Introduction
To draw: The illustration for resulting potentials for all possible combination of E1, E2 and I
Introduction: The graded potential arises during resting, depolarization, and action potential. The gated channels help in the movement of ions from the extracellular region to the intracellular region.
Explanation of Solution
The graded potential (mV) in the axonal membrane is shown below:
- 1-represents the weak excitation (E1)
- indicates the stronger stimulus (E2)
- represents the inhibitory stimulus (I) produced by the hyperpolarization.
- represents the sum of all resulting graded potential
Pictorial representation: Fig 1 represents resulting potentials for all possible combinations.
Fig 1: represents resulting potentials for all possible combinations.

Which of the following is the most likely to occur in neurones following application of 0.03 mM X? Action potentials would be prolonged and the resting potential would be depolarised. Action potentials would be prolonged but the resting potential would remain the same. Neither resting potential nor action potentials would be affected because the concentration of X is less than the IC50 value.
