Glucose enters cells most rapidly by

Glucose enters cells most rapidly by Facilitated Diffusion. This is a process in which molecules and ions are transported through the cell's membrane using proteins that are specifically created for that function. It's passive which means it doens't require energy, which is great for glucose because glucose is a carbohydrate, essentially energy, so more energy is created than lost.
