What are the key steps of in the reabsorption movement of NA+ in the tubule?

In the proximal tubule, Na+ is important for 1____ for of substance such as 2____

In carrier-mediated transport the plasma concentration at which saturation occurs is the?

Saturation occurs when all available 1._____ are fully occupied by 2._____

Sodium is a 1____ charged ion. This sets up a gradient for 2____ charged ions such as 3____

Carrier-mediated transport is are unsaturable because any filtered fluid gets reabsorbed.

In the kidney, the concentration gradient of Na+ is often used to transport what substances?

When saturation occurs the rate of transport cannot increase any further. This is known as the?

What drives water reabsorption in the proximal tubule across the epithelial layer?

After transportation glucose then diffuses out of the cell across the 1___ membrane via a 2____

What pumps NA+ out to keep the {Na+} inside the cell low?

In secondary active transport Glucose enters the cell via _______?

The ends of proximal tubule become more concentrated creating a 1_____ for the 2____ of urea
