PART 1: (select the correct bold-facedchoices)
Glucose is freely [\"secreted\", \"filtered\", \"excreted\",\"reabsorbed\"] at the glomerulus, where it enters thetubule of the nephron. However, all of the glucose entering thenephron is normally [\"secreted\", \"filtered\", \"excreted\",\"reabsorbed\"] at the proximal convoluted tubule via thesodium-glucose co-transporter, which also reabsorbs Na+.Glucose is not [\"secreted\", \"filtered\", \"excreted\",\"reabsorbed\"] into the nephron tubule. Because of this, noglucose is [\"secreted\", \"filtered\", \"excreted\",\"reabsorbed\"] in a healthy individual.
PART 2: Why is protein not found normally foundin the urine?
A. It is fully absorbed by the digestivesystem
B. It is 100% reabsorbed by the nephron
C. It is 100% secreted by the nephron
D. It is too large to be filtered
