There are over 10 different types of glucose transporters; however, the most significant for study are GLUT1-4. GLUT1 and GLUT3 are located in the plasma membrane of cells throughout the body, as they are responsible for maintaining a basal rate of glucose uptake. Basal blood glucose level is approximately 5mM (5 millimolar). The Km value (an indicator of the affinity of the transporter pro… Web8 de mai. de 2024 · Aug 5, 2009. #2. Km and Vmax are related to enzyme kinetics in a biological system. Km is the substrate concentration that is required for the reaction to occur at 1/2 Vmax. In other words, it is how much substrate is needed for the reaction to occur at 1/2 its max possible rate. Obviously Vmax is the maximum rate that the reaction can … huda beauty lip sets
