Question
For the next few questions, think about the rules for diffusion of uncharged molecules (nonpolar), and use these answer choices: a) Increase b) Decrease 23) An increase in membrane thickness will diffusion of nonpolar molecules and gases across that membrane. 24) Increasing the concentration of a steroid hormone outside the cell, while holding its intracellular concentration steady, will its diffusion into the cell. 25) As a cell grows and increases in surface area, diffusion of nonpolar molecules and gases across its membrane willExplanation / Answer
Answer 23: Decrease, based upon ficks law of diffusion, rate of diffusion is inversely proportional to thickness of the membrane.
Answer 24: Increases, due to concentration gradient based upon ficks law of diffusion. Rate of diffusion is directly proportional to the concentration gradient.
Answer 25: Increases, due to ficks law of diffusion. Increase in surface area increase the rate of diffusion.
