<prompt> Active reabsorption of glucose occurs in the ?Distal tubuleProximal tubuleLoop of henleCollecting ducts  <response>: B i.e. Proximal tubuleProximal convoluted tubule early pa reabsorbs almost all of glucose, amino acids, protein, lactate inorganic phosphate and most 65 of bicorbonate,Na,110, K and CI Q.
