Insulin leads to glucose catabolism??????

[libraryismyhome]

EK bio says that Insulin works to reduce the [Glucose] in the blood and to promote glycogenesis in liver and muscle (making glycogen).

However, I found out from several BR questions that insulin promotes the usage of glucose, so more CO2 is released via catabolism.
WHAT????????

My presumption to these BR questions is that, it happens because reducing the [Glucose] in blood means increasing the [Glucose] in the cell cytoplasm and mitochondria, so there is more catabolism???

From what I know, insulin enhances the uptake of glucose from the blood into cell by glucose carrier, where, later, it will be used as a building block to add to glycogen chain.

On the other hand, glucagon triggers the phosphorylation and hydrolysis of glycogen, releasing glucose that will, later, be fully oxidized to CO2.

Therefore, insulin has no direct lead to the increase the oxidation of glucose.

the point of insulin is to get glucose into cells.

the point of glucose is for cells to use them
