In a Voltage Clamp Experiment, You Observe That the Magnitude

question 23

Multiple Choice

In a voltage clamp experiment, you observe that the magnitude of the sodium current decreases when the membrane potential is stepped between +10 and +50 mV. Why?

• A) The driving force on sodium decreases as membrane potential increases.
• B) The equilibrium potential for sodium decreases as membrane potential increases.
• C) The voltage difference opens fewer sodium channels as membrane potential increases.
• D) The resting potential of the neuron decreases as membrane potential increases.
• E) The leak conductance decreases as membrane potential increases.

Definitions:

Median

The middle value in a data set, which separates the higher half from the lower half of the data.

Extreme Values

The smallest or largest values in a data set or distribution, often considered as outliers or as significant for their rarity.

Variation

Variation refers to the extent to which data points in a data set differ from each other and from the mean of the dataset.

Standard Deviation

A measure that quantifies the amount of variation or dispersion of a set of data values from the mean value.
