Good morning Pisces! [sorry! ]

I think it is best if you first assume that your answer to part iii) is "substrate conc-n", yeah?

i) You draw a line that starts same point [origin] then rises slower with increasing values of x [conc-n] [why?] and then levels out at the same level as the given line [Why?]

ii) A line as above rising slower again but levelling out at a lower y value [Why?]

iv) Your job to work out from above.

Be safe!

Thank you so much! I am so grateful. Would it be like this?

Z is correct [except that the transition from the slowly increasing bit to the horizontal bit should be more gentle/curved RATHER THAN angular.

Technically, Y should level out higher [so after continuing the first rising bit to just about the level of the given graph.

It is no good just drawing the right lines - have an attempt at explaining why these graphs [Y and Z] [will] look like they do.

OTHERWISE:
When u r faced c another DIFFERENT Q, you will struggle again!

That is perfect! Thanks so much. I understand it now. I have a test next week so hopefully if something like this comes up I will know how to approach it.
