What Are The Two Mechanisms Of Tubular Reabsorption? Mechanisms by which substances move across membranes for reabsorption or secretion include simple diffusion, facilitated diffusion, active transport, secondary active transport, and osmosis. Simple diffusion moves a substance from a higher to a lower concentration down its concentration gradient. What is the process of tubular reabsorption? Tubular
Why Does Selective Reabsorption Occur At The Proximal Convoluted Tubule? Selective reabsorbtion occurs in the PCT (proximal convoluted tubule). The PCT is highly permeable meaning it is easy for molecules to diffuse through it. How does reabsorption occur in the proximal convoluted tubule? Fluid in the filtrate entering the proximal convoluted tubule is reabsorbed into
What Is Active And Passive Reabsorption? For glucose reabsorption, secondary active transport occurs at the luminal membrane, but passive facilitated diffusion occurs at the basolateral membrane, and passive uptake by bulk flow occurs at the peritubular capillaries What is active reabsorption? Most of the reabsorption of solutes necessary for normal body function such as amino
