Correct Answer � A
Explanation
|
|
Ans: A. Glucose
- The given graph is similar to the Michaelis-Menten Curve for enzyme kinetics hence describes carrier-mediated transport with saturation kinetics.
- Among the options, only Glucose shows facilitated diffusion via carriers (SGLT & GLUT).
- Others are transported by simple diffusion showing a straight line without saturation.
