1.3 Electrochemical Gradeienr/ Membrane Potential

Question 1

For a solute carrying a net charge, what combines to form the electrochemical gradient which determines the transport of the solute

Answer 1

The concentration gradient and the electrical potential difference (voltage)

Question 2

Why does the electrochemical gradient form

Answer 2

Due to the net positive charge outside the cell and the net negative charge inside the cell

Question 3

What creates a membrane potential

Answer 3

It is created when there is a difference in electrical charge on the two sides of the membrane
