Which values reflect the expected glucose concentrations (in mM) in micropuncture samples collected from the nephron in the following order: Bowman's capsule, beginning of proximal convoluted tubule, intermediate segment, middle of distal convoluted tubule, and beginning of collecting duct?

Question

Quizplus · Accepted Answer

Glucose is freely filtered in the glomerulus, so its concentration in Bowman's capsule and the beginning of the proximal convoluted tubule is similar to plasma. It is then reabsorbed in the proximal tubule, so it should be absent (0 mM) in later segments of the nephron.
