![**Diagram Explanation: Neuronal Cell Membrane at Rest**
This diagram illustrates the structure and function of a cell membrane, specifically highlighting the channels involved in ion movement across the membrane, contributing to the membrane's resting potential.
- **A. Sodium-Potassium Pump:** This is an essential protein that helps maintain the resting potential of the cell by actively transporting 3 sodium ions (Na⁺) out of the cell and bringing 2 potassium ions (K⁺) into the cell against their concentration gradients using ATP.
- **B. Sodium Ion (Na⁺):** Sodium ions are shown on both sides of the membrane but are more concentrated outside the cell.
- **C. Potassium Channel:** These allow the passive movement of potassium ions (K⁺) out of the cell, contributing to the negative charge inside the cell.
- **D. Sodium Channel:** Although shown here, sodium channels are typically closed at rest, preventing Na⁺ influx.
- **E. Leak Channels:** These channels allow for the passive movement of ions, such as K⁺, maintaining the negative resting potential inside the cell.
**Question:**
This cell is at rest.
- [ ] True

Expert Solution
Step 1
The movement of the ions across the membrane generates the electrical potential called the Membrane potential. The ions move through the ATP-driven pump and ion channels such as leaky channels and gated channels.
