- 1 and half page long answering this please Describe the difference between passive and active forms of transport across a cell membrane. Describe a form of passive and a form of active transport. What about bulk transport?Fast solution needI believe I use the diffusion law on this: (Diffusion Constant × ∆Concentration × Area) / Thickness. Then change the constant into micrometers (x10^-12). Maybe use the fact that oxygen = 16 grams/mol. Am I on the right track? Thank you for any help you can provide.
