at rest (-70 mv) the electrical force of na+ wants to move na+ .... the cell.
Homework Answers
At rest exterior of cell show more positive charge and inside is negative. So at rest electrical force of na+ wants to move na+ inside the cell.
Add Answer to:

1- During an action potential, Na+Na+ ions move into the cell at a rate of about 3×10−7mol/m2⋅s3×10−7mol/m2⋅s. How much power must be produced by the "active Na+Na+ pumping" system to produce this flow against a +30−mV+30−mV potential difference? Assume that the axon is 60 cmcm long and 30 μmμm in diameter. Express your answer using two significant figures. 2- A 4.80-mm length of 2.6-mmmm-diameter wire carries a 850 mAmA current when 19.0 mVmV is applied to its ends. If the...

The resting membrane potential of a neuronal axon is -70 mV. When an action potential is triggered, Na+ ions move into the axon, which reverses the voltage, bringing it towards 0 mV. Which of the following is the correct term for this sequence of events? a. Repolarization b. Hyperpolarization c. Depolarization d. Hypopolarization e. Isopolarization
