Question 24 In a laboratory experiment, you measure the rate at which two compounds (A and B) cross a phospholipid 18 46 100 125 130 0.1mM 0.3mM 20 60 200 10mM Which compound lanswer with A or B) traverses the membrane by simple diffusion? Which compound traverses the membrane by facilitated or active transport? One of the compounds is ethanol. CHjCH 0H and the other is acetate CH coo Which one is A and which is B? CH3CH2OH is CH&COO; is Previous ao@ SAMSUNGExplanation / Answer
Answer:
The rate of simple diffusion is directly proportional to the concentration gradient and the membrane permeability of the solute molecule, whereas the facilitated diffusion depends on the kinetics of carrier-mediated transport.
The compound which traverses by simple diffusion=A
The compound which traverses by facilitated diffusion=B
Small polar molecules such as oxygen, ethanol, and carbon dioxide traverse by simple diffusion.
CH3CH2OH IS COMPOUND A
CH3COOH IS COMPOUND B
