During an action potential, activation of voltage-gated sodium and potassium channels occurs at different rates. what is the effect of this difference on ion flow across an axon membrane? during an action potential, activation of voltage-gated sodium and potassium channels occurs at different rates. what is the effect of this difference on ion flow across an axon membrane? k+ will flow into the cell first and then na+ will flow out of the cell. initially, na+ flows into the cell and then k+ flows out of the cell. sodium ions flow out of the cell, then potassium ions flow out of the cell. first, sodium ions flow into the cell, and then potassium ions flow into the cell.

Na+ flows into the cell and then K+ flows out of the cell

Explanation:

When the cell is at rest potential, Na+ is more highly concentrated on the outside of the cell, and K+, on the inside of the cell. During an action potential, the plasma membrane depolarizes, Na+ channels are opened and Na+ starts flowing into the cell, in favor of its electrochemical gradient. When this happens, K+ will also be opened and K+ will start flowing outside the cell, causing the membrane potential to go back to its rest value.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
