Because maybe you ate more glucose than you needed immediately and so it goes into cells that can store glucose.
因为你摄入的糖可能比你需要的糖更多,因此它们就进入那些有储糖能力的细胞中

Failure to maintain tight control of glucose levels - by measuring blood sugar with a meter and compensating with doses of insulin - can result in serious health complications, including blindness, kidney failure and heart disease.
VOA: standard.2010.04.15

So, that brings your glucose level down.
这就导致了血糖水平的降低
-
The pump developed by researchers is a double pump - in addition to insulin, it automatically secretes glucagon, a hormone that taps glucose reserves in the liver, raising blood sugar levels when they get too low, a condition called hypoglycemia.

Now when you want to maintain good health, high peaks, high spikes in blood glucose and the insulin response that provokes is not a very good thing, and so the red line is a far healthier way to be than the yellow line is.

-
In order for glucose to enter our body it has to go through the cells.
如果葡萄糖要进入身体,它必须穿过上皮细胞
-
Because of that, if I eat something that's rich in glucose, so it has lots of sugar molecules, the sugar molecules can't pass between the cells.
因此,如果我吃了富含葡萄糖的食物,尽管其含有很多的糖分子,但糖分子不能从细胞间通过
-
Diabetics whose pancreas does not function properly, so don't make enough insulin, don't have enough insulin present for normal glucose metabolism so they can't handle sugars properly.
