    Reabsorption in tubules of nephrons occurs by:

    A)  Osmosis                                             

    B)  diffusion           

    C)         Alteration         

    D)         active transport

    Correct Answer: D

    Solution :

    Epithelial cells throughout the length of tubule carry out reabsorption. During this process, specific amounts of certain substances reabsorbed depending on the body needs at the time. Substances are reabsorbed by both active and passive transport mechanisms. In the proximal convoluted tubule glucose and small proteins are reabsorbed by active transport mechanism.
