For my science homework I have to complete a sheet on the effects of smoking. There are a couple of questions that I am really struggling with please could you help? These are the questions:
Describe what effect the loss of surface area would have on the health of a smoker?
Describe what effect the blocked cilia would have on the health of a smoker?
Thanks a lot! X
It comprises of phosolipids right? The phosphorus is hydrophilic, and the fatty acids hydrophobic. I asked my teacher how the water diffused in and out of the membrane then, and she said. "The water molecules are small enough that they just go through"
Now. I know I'm the student, but that doesn't fit with me? Then I learnt about the transport protiens. And that made more sense.
But, is that the defenite way, and if so, what really happens in the process of water going in and out of the membrane?
