Question

in a non - diabetic, glucose ______ .
a is found in the filtrate and is reabsorbed, but still occurs in the urine
b never leaves the blood plasma
c is filtered and completely reabsorbed
d is filtered, but not reabsorbed

Explanation:

To solve this, we analyze each option:

• Option A: In non - diabetics, glucose is reabsorbed completely, so it should not be in urine. So A is wrong.
• Option B: Glucose does leave blood plasma during filtration in the kidneys. So B is wrong.
• Option C: In non - diabetic individuals, when blood is filtered in the kidneys (glomerulus), glucose is present in the filtrate. Then, in the renal tubules, all the filtered glucose is reabsorbed back into the bloodstream. This is correct.
• Option D: Glucose is reabsorbed, so this is wrong.

Answer:

C. is filtered and completely reabsorbed
