What is the first step in triggering a change in membrane potential?

Biology
1 answer:
Sophie [7]3 years ago
4 0

Answer:

The membrane potential is maintained in the cell due to the unequal distribution of the ions inside and outside of the cell. This membrane potential is important for the conduction of the nerve impulse.

The arrival of the stimulus triggers the action potential. The resting membrane potential is -70mV. This is maintained by the presence of potassium ions. The influx of the sodium ions result in the change in the membrane potential from -70mV to +30mV.

6. Would there be a net flow of water in one direction in the following situations? Explain your answers.
amid [387]

Answer: There won't be a net flow of water in one direction in the situation.

Explanation: The concentration of NaCl inside the cell and its concentration outside the cell is the same. This means that there is equilibrium (a balance) between the inside environment of the cell and the outside environment of the cell. And because there is equilibrium between the two sides there will not be a net flow of water in one direction. The flow of water must be in opposite directions (inside and outside) so as to maintain a balance between the two environments.
