Keep your AP biology students up to speed with a look at the mechanism of ATPase in this beautifully animated tour from the creator of "Inner Life of the Cell." Check it out at: https://www.labxchange.org/library/items/lb:LabXchange:35c0178d:video:1 | LabXchange

The Na /K -ATPase (aka Sodium-Potassium pump aka Lil Pump) These pumps are responsible for up to 75% of the energy expenditure of neurons. They use ATP (purple flash in this animation) to pump three sodium ions (yellow) out of the cell and pump two potassium ions (green) into the cytoplasm. The Na /K -ATPase is crucial to maintain the membrane potential. | Ribosome Studio
