Question

The nephron uses counter-current exchange between the loop of Henle and peritubular capillary to reabsorb glucose back in to the blood and is why glucose should not be found in the urine.
a. True
b. False

Answer 1

Answer:

The answer to the question: The nephron uses counter-current exchange between the Loop of Henle and peritubular capillaries to reabsorb glucose back into the blood as this is why glucose should not be found in the urine:___, is, false.

Explanation:

The process of urine processing as filtrate goes through a nephron´s different portions, is pretty complex, but fascinating. Initially, water, certain substances as glucose, sodium, and others, pass through the glomerulus intoo the PCT (Proximal convoluted tubule) where the initial filtrate is formed. This filtrate will then move through other portions to be added to, and substracted from, on different elements, until finally, at the very end, urine is produced. However, one molecule that is reabsorbed early in this process of filtrate production, is glucose. Glucose should not be usually present in urine, unless there has been a huge consumption of it and transporters in the PCT cannot deal with the amount being filtered, or there is a condition like diabetes mellitus. It is in the PCT that glucose reabsorption is done, together with sodium ions. This is why the answer to the statement is false.
