What Causes the Rapid Change in the Resting Membrane Potential

question 23

Multiple Choice

What causes the rapid change in the resting membrane potential that initiates an action potential?

• A)Potassium gates open and potassium rushes into the cell, changing the membrane potential from negative to positive.
• B)Sodium gates open and sodium rushes into the cell, changing the membrane potential from negative to positive.
• C)Sodium gates close allowing potassium into the cell to change the membrane potential from positive to negative.
• D)Potassium gates close allowing sodium into the cell to change the membrane potential from positive to negative.

Definitions:

Standard Normal Distribution

A probability distribution with a mean of 0 and a standard deviation of 1, often used in statistical analysis.

Standard Deviation Units

Units of measurement derived from the standard deviation, used to quantify the variation or dispersion of a set of data points.

Bell-Shaped

Describes the graphical representation of a normal distribution, where most values cluster around a central peak and the distribution tapers off symmetrically towards both tails.

Standard Normal Distribution

A distribution of probability that displays symmetry around its mean, highlighting that instances near the mean happen more often than those far from it.
