Master the molecular machine that powers life itself!
Resting Potential: Creates the -70 mV charge neurons need to fire
Cell Volume: Prevents cells from bursting by controlling water flow
Energy Battery: Powers 30% of your body's ATP usage!
This pump trades ions across your cell membrane:
• Pumps 3 Na+ ions OUT
• Brings 2 K+ ions IN
• Uses 1 ATP for energy
Result: Cells become negatively charged inside!
