| phospholipids and proteins |
| acids and bases |
| carbohydrate molecules |
| water molecules |
| cations and anions |
Homework Answers
Answer:
cations and anions
Explanation: The resting membrane potential results from the uneven distribution of ions across the cell membrane and difference in membrane permeability to Na+ and K+.

A typical cell has an electric potential difference across its cell membrane, The electric potential interior to the cell is 70mV less than that on the exterior. Under certain circumstances, the cell can redistribute charge so that the electric potential inside is 40 mV greater than that outside. Assuming the membrane is 12 nm thick and that the net electric field inside it is uniform, how does that field change in the transition from having an interior that is 70...

Ion channels that switch open and close as the potential difference across the cell membrane changes...
Ion channels that switch open and close as the potential difference across the cell membrane changes are an essential component of the cell membrane. Most such channels contain a molecular ion with a significant electrical charge at their core. Suppose a protein contains a molecular ion with a charge of -12e and that this protein is embedded in a cell membrane that has a thickness of 9 nm. What are the magnitude and direction of electric force on the ion...

Solid-state electrodes that respond to anions create a potential difference across the solid-state membrane by _______, which allows anions to migrate through the crystal. A. polishing the surface of the membrane crystal B. drilling small channels through the crystal C. doping the membrane crystal to create anion vacancies D. etching the surface of the membrane crystal with small grooves E. reacting the membrane crystal with a strong acid
The action potential occurs when the voltage across a cell membrane experiences an increase from the...
The action potential occurs when the voltage across a cell membrane experiences an increase from the resting potential (−70.mV) to about 30.mV. This depolarization, in turn, causes a similar response all along the cell membrane; the result is an electrical impulse that sends a signal along the axon of a neuron. The cell membranes can be about 5.0nm across and have an electric field across them due to the change in potential. What is the electric field across the membrane...
