Use the mouse to highlight the answers. They are written in white
Question | Answer | Link |
To which ion is most transport in the proximal tubule linked? |
Sodium |
Link |
Which transporter found in the basolateral membrane is essential to maintain low intracellular sodium levels? |
Sodium/potassium ATPase |
Link |
Why does the concentration of the tubular fluid remain constant along the tubule despite the reabsorption of ions such as sodium? |
Water passively follows the reabsorbed sodium so the concentration remains fairly similar but the volume is reduced |
Link |
When being reabsorbed alone how does sodium enter the epithelial cells? |
Via ion channels |
Link |
Sodium is able to leave the intersitium and enter the blood because...? |
The blood has a low hydrostatic and high protein osmotic pressure |
Link |
What is the main route of potassium reabsorption from the proximal tubule? |
paracellular |
Link |
Potassium is cleared from the cell using a co-transporter with which other ion? |
Chlorine |
Link |
How is glucose reabsorbed? |
Co-transported with sodium |
Link |
The plasma concentration at which glucose can first be detected in the urine is called? |
The renal threshold for glucose |
Link |
Define Splay? |
Between the renal threshold and T-Max the amount of glucose filtered and the amount of glucose in the urine is not linearly related. This is becuase some nephrons have a greater capacity for reabsorbtion than others and are not overcome as easily. |
Link |
Define T Max? |
Is the point at which every nephron is running at full capacity of reabsorping glucose. After this point the glucose cocentration filtered and excreted increase linearly. |
Link |
How is hydrogen excreted? |
Sodium/hydrogen antiporter |
Link |
Which enzyme is pivotal in the reuptake of bicarbonate? |
Carbonic anhydrase |
Link |
How is protein reabsorbed? |
Endocytosis |
Link |
What is the name of the process by which many drugs are excreted into the proximal tubule? |
Primary Active Secretion |
Link |
