Na, K-ATPase conformational change E1 to E2

---

Na, K-ATPase conformational change where E1 becomes E2 is associated with phosphorylation of ——– residue of E1

[A] Valine
[B] L-glutamate
[C] Aspartate
[D] Pyruvate

Na, K-ATPase – E1 and E2

---

1. Forms of Sodium Pump – Na+-K+ ATPase exists in two forms: E1 and E2.
2. Phosphorylation of aspartate residue of E1 with the help of ATP and Mg++ results in conformational change and E1 becomes E2
3. Dephosphorylation changes the conformation of E2 to E1
