Describe the process of bicarbonate reabsorption.
1. Bicarbonate is filtered by the glomerulus
---Inside the tubule it associates with to form
2. catalyses the of carbonic acid into
---These can then be into the tubular cells
3. Inside the cell, catalyses the reaction between H2O and CO2 to form again
4. The carbonic acid then into again
5. ensures that the ions are transported in the right directions:
---H+ is , as H+ channels are only found on the side
---Bicarbonate is , as bicarbonate channels are only found on the side
