Final answer:
The Proximal Convoluted Tubule (PCT) is the area where all amino acids and glucose are reabsorbed in the nephron.
Step-by-step explanation:
The area of tubular reabsorption in which all amino acids and glucose are reabsorbed is the Proximal Convoluted Tubule (PCT). In this part of the nephron, the filtered fluid collected by Bowman's capsule enters the PCT, which is characterized by a tortuous path and lined with simple cuboidal cells that have prominent microvilli forming a brush border. These microvilli create a large surface area that facilitates the maximum absorption and secretion of solutes such as Na+, Cl-, glucose, etc., which is the primary function of the PCT. The cells here actively transport ions across their membranes and have a high concentration of mitochondria to produce the ATP necessary for this process.
