    Which region of the kidney nephron is the main site of amino acid reabsorption?

    A) glomerulus

    B) Bowman's capsule

    C) proximal convoluted tubule

    D) distal convoluted tubule

    Correct Answer: C

    Solution :

    [c] A and B involve ultrafiltration. In the proximal convoluted tubules the mitochondria provide energy for active transport. The cells present here are adapted for reabsorption. The amino acids diffuse into the cells and are actively transported to the intercellular spaces, where they diffuse into the surrounding capillaries.
