How does glucose get into the cells?

Question

Please explain, detail would be good. Thanks

Answer 1

Glucose travels through sodium-glucose (Na+/glucose) transport proteins located in the plasma membrane.

A sodium ion is pumped out of the cell ("up" its gradient) then diffuses back into the cell ("down" its gradient) together with a glucose molecule ("up" its gradient). It is an example of indirect active transport. Active transport is required for glucose since the concentration of glucose is higher inside a cell than outside (it moves "up" its gradient).
