Glucose uptake refers to the process by which cells absorb glucose, a simple sugar that serves as a primary energy source for the body. This process is essential for maintaining energy levels and supporting various cellular functions. Glucose enters cells through specialized proteins called transporters, which facilitate its movement across the cell membrane. Insulin, a hormone produced by the pancreas, plays a crucial role in regulating glucose uptake. When blood sugar levels rise after eating, insulin is released, signaling cells to increase their uptake of glucose. This helps lower blood sugar levels and ensures that cells have the energy they need to function properly.
