Hi, Can anyone point me in the right direction of the bottom please as they are 2 parts to my question, I have to do?
PART 1
Evaluate how Osmosis and simple diffusion work by comparing their similarities and differences, looking at how the processes work and how molecules are transported?
( i help to find the differences and similarities between the two)

PART 2
evaluate the importance of facilitated diffusion and active transport in cells, including any similarities and differences. To do this, I need to use examples of when these types of transport are used by cells. Why is it essential to have two systems of transport, active and passive to allow substances to enter and leave cells and why molecules would be transported by one rather than the other?
( need to find out the differences and similarities of the two, why it is important to have two systems for transport)

Thank you for any help that can be provided

For part 1, talk about what is transported by these processes generally, what governs th rate of transport by these mechanisms, any requirements for these processes, things like that.

Part 2: probably the same as above

I think maybe you got help with part 1 so for part 2
Both systems help transport molecules in and out of the cells. The main difference between Facilitated Diffusion and Active Transport is that FD does not use energy (so its passive) but AT expend energy. On the similarity side of it; both are specific, use carrier proteins, and they saturate at high concentrations i.e. when all carrier proteins are occupied. If you need more or a hand with any assignment, feel free to DM me. I hope that helps x.

would you say it is important to have two systems of transport cause one transports large molecules and the other transports small molecules or something along that line?

Yeah, sure. As long as you support the point well.
