NettetGlucose is an important fuel for contracting muscle, and normal glucose metabolism is vital for health. Glucose enters the muscle cell via facilitated diffusion through the GLUT4 glucose transporter which translocates from intracellular storage depots to the plasma membrane and T-tubules upon muscle contraction. Here we discuss the current … Nettet7. apr. 2024 · What type of facilitated diffusion is involved in insulin secretion? There are hexose transporters on the walls of the cells throughout the body that are a part of this type of facilitated diffusion. When the concentration of insulin is decreased, transporters inside cytoplasmic vesicles, GLUT4 transporters (the major transporter for blood sugar …
