Detailed explanation-1: -Final answer: Glucose is completely reabsorbed in the kidneys.
Detailed explanation-2: -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.
Detailed explanation-3: -Glucose is completely reabsorbed in the kidney.
Detailed explanation-4: -Most of the glucose entering the tubular system is reabsorbed along the nephron segments, primarily in the proximal tubule, such that urine is almost free of glucose. This is different in diabetes, where the filtered glucose exceeds the transport capacity of the tubular system for glucose and glucosuria occurs.
Detailed explanation-5: -Glucose, amino acids are actively reabsorbed in the nephron and water, other ions is passively reabsorbed.
