Question
Chapter 20.2, Problem 7CC
Summary Introduction
To determine: The reason for people prescribed on loop diuretic has increased the consumption of potassium in their diet.
Introduction: Diuretics are also called “water pill.” These facilitate kidney to excrete unused water and salts from the body. Diuretics help the heart to pump blood efficiently. These are prescribed to patients having a heart and kidney disorder.

Explain how the VERY commonly prescribed medication Lasix, which blocks the NKCC-mediated transporter, works as such a powerful diuretic. Include the direct effect(s) and the INdirect effect(s) blocking this transporter has on the water retention/concentration abilities of the kidneys - structures affected (nephron sections, kidney structures), etc. Also address how this medication may affect sodium and potassium concentrations in the body.
Which of the followings is correct about chloride reabsorption from the loop of Henle?
Cl – is reabsorbed through the chloride channels of cells of the thick segment of loop of Henle
Cl – is reabsorbed through paracellular gaps of the thick segment of loop of Henle
Cl– is reabsorbed through Na–K–2Cl cotransporter in the basolateral membrane of the thick segment of loop of Henle
All of the above is are correct
None of the above is correct
Atrial Natriuretic Peptide helps to reduce overall blood pressure in a variety of ways. One way is by increasing Glomerular Filtration Rate.
a. Why/how would increasing GFR cause decreased blood pressure? b. To increase GFR, would Atrial Natriuretic Peptide cause constriction or dilation of afferent arterioles at the kidneys? The efferent arterioles?

- The Na+-glucose transporters SGLT2 and SGLT1 are located at different levels of the kidney proximal tubule to minimize spillover of the glucose into the urine (See diagram attached) a) Consider the Na+-glucose coupling ratios for SGLT2 and SGLT1. Why would localization of SGLT2 in the early proximal tubule and SGLT1 in the late proximal tubule be advantageous? b) The Michaelis constant (Km) for the SGLT2 and SGLT1 transporters are 2 mM and 0.5 mM, respectively. Is SGLT2 or SGLT1 the higher affinity Na+-glucose transporter? d) Dapagliflozin is an SGLT1 inhibitor and commonly prescribed to treat type 2 diabetes. Why would this be of benefit to a diabetes patient?arrow_forwardAngiotensin Converting Enzyme (ACE) is produced by endothelial cells throughout the body, but the majority is produced in the lungs. Some pulmonary disorders actually lead to an increase in ACE production. Consider what the consequences of this might be both directly on sodium balance, and indirectly on water balance.
