Web51.5 How Does the Mammalian Kidney Produce Concentrated Urine? The proximal convoluted tubule (PCT) is responsible for most reabsorption of water and solutes. • PCT cells have microvilli to increase surface area, and have mitochondria. • They actively transport Na +, glucose, and amino acids. • Water follows the transport of solutes.
