This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Transpo Processes, Subject name: Physiology
Active transpo and facilitated diffusion share which of the following characteristic: 
Select and explain. 
A. Competitive inhibition does not occur, B. Requires non-specific carrier protein, C. Transpo solute against concentration gradient, D. Follows Michaelis Menten kinetics
D: Follows Michaelis Menten kinetics
Answer: D: Follows Michaelis Menten kinetics 
Explanation: Active transpo and facilitated diffusion both are carrier mediated transpo exhibits saturation kinetics or Michaelis Menten kinetics, specificity (i.e; specific carrier protein is required to transpo specific solute across the plasma membrane) and competitive inhibition. Facilitated diffusion is passive transpo and does not requires ATP.
