The graph given below denotes the transport kinetics across the cell membrane. The solute is:
Ans. C. Glucosea. Rate of glucose entry is almost zero without the transporter molecule helping in facilitated diffusionb. Glucose concentration determines the rate of transport: Km can be calculated from the half maximal ratec. Km (glucose): 1.5mMd. Value of Km gives information regarding the affinity of the transporter to glucosee. Affinity is inversely proportional to Km.f. There is a favorable free energy for glucose transportg. Blood glucose concentration is roughly 65-90mg/dL
