About the Lecture
The lecture Sodium-potassium ATPase – Protein Functions by Kevin Ahern, PhD is from the course Biochemistry: Basics.
Included Quiz Questions
Which of the following is true of the sodium-potassium ATPase?
- It requires ATP to move sodium against its concentration gradient.
- Three potassium ions are moved out of the cell for every pair of sodium ions that are moved into the cell.
- It uses potential energy from the sodium gradient to move potassium.
- It is embedded in the mitochondrial membrane.
- Both sodium and potassium move down their concentration gradient.
