[{'content': "Common for both simple and facilitated diffusion is: \nSelect and explain. \nA. Can be blocked by specific inhibitors, B. Follows Fick's Law, C. Follows saturation kinetics, D. Transpo along the concentration gradient", 'role': 'user'}, {'content': "Answer: D \nExplanation: Common factor between Simple and Facilitated diffusion is that they both transpo solute along the concentration gradient. Facilitated diffusion is a passive transpo mechanism that does not requires use of ATP and involves a carrier protein and it follows saturation kinetics. Fick's law of diffusion is followed by simple diffusion only..", 'role': 'assistant'}]
