Where does reabsorbtion of glucose take place? glomerulus
bowman's capsule
2nd coiled tubule
1st coiled tubule

proximal tubule

Explanation:

Glucose reabsorption takes place in the proximal tubule of the nephron, a tube leading out of Bowman's capsule. The cells that line the proximal tubule recapture valuable molecules, including glucose.Under normal circumstances, up to 180 g/day of glucose is filtered by the renal glomerulus and virtually all of it is subsequently reabsorbed in the proximal convoluted tubule.
