Summary Introduction

To review:

The three different types of transportation processes that are involved in the carrier proteins in the renal tubule and collecting systems.

Introduction:

Carrier proteins represent integral membrane proteins that may assist in the movement or migration of substances by facilitated diffusion or active transport. Many solutes that are secreted and reabsorbed through the transcellular route need the help of a carrier protein in the tubule cell's plasma membrane. Thus, they facilitate the diffusion of substances across the plasma membrane.
