glucose uptake

Glucose uptake is the process by which cells absorb glucose, a type of sugar that provides energy. When blood sugar levels rise after eating, the pancreas releases insulin, a hormone that signals cells—especially in muscles and fat tissue—to open special doors called receptors. These receptors allow glucose to enter the cells, where it is used for energy or stored for later. This process helps regulate blood sugar levels and supplies cells with the fuel they need to function properly.
