What would be the effect if sodium were suddenly allowed to move freely through the membrane above? TRUE OR FALSE:
1. Glucose would no longer be transported against its gradient.
2. Sodium would be able to freely diffuse against its gradient.
3. Sodium would continue to be pumped through the Na+-K+ ATPase
4. Glucose would continue to be pumped through the Na+-glucose symporter.
5. ATP would continue to be consumed by the Na+-K+ ATPase.
6. The sodium gradient across the membrane would not change.
