Tag: Secondary active transport

The human body requires a constant supply of amino acids for protein synthesis and other metabolic processes. This process is not passive; it relies on complex and specialized transport systems to ensure these vital building blocks are moved efficiently from the diet and across cellular membranes.

Over 80% of glucose filtered by the kidneys is reabsorbed via SGLT2, illustrating the body's high-capacity absorption methods. In the small intestine, glucose is absorbed through a combination of secondary active transport and facilitated diffusion, depending on the concentration of glucose in the intestinal lumen. This dual-mechanism process ensures efficient and rapid uptake of dietary sugars into the bloodstream after a meal.
