The individual fasts overnight, then drinks a test dose of 100 g of glucose dissolved in a glass of water. The blood glucose concentration is measured before the test dose and at 30 min intervals for several hours thereafter.
B.
A healthy individual assimilates the glucose readily, the blood glucose rising to no more than about 9 or 10 mM; little or no glucose appears in the urine.
C.
In diabetes, individuals assimilate the test dose of glucose poorly; their blood glucose level rises dramatically and returns to the fasting level very slowly.
D.
Because the blood glucose levels exceed the kidney threshold (about 10 mM), glucose also appears in the urine.
【单选题】Because glucose has several metabolic routes it might take once it arrives in the cytoplasm, which one of the following reactions would commit the glucose to following the glycolytic pathway?
A.
Glucose to glucose 1-P
B.
Glucose to glucose 6-P
C.
Fructose 6-P to fructose 1,6-bisP
D.
Fructose 1,6-bisP to dihydroxyacetone phosphate and glyceraldehyde 3- P
