Substrate Concentration on Enzyme Activity (1 Viewer)

[Grinchey]

Hey all,

I did my practical exam for Biology on Wednesday, and for the substrate concentration graph I had the right shape, labelled the axes, titled the graph, used a pencil though I used a ruler to join up each point on the curve. Is this okay, or will I drop marks (if so how many?; it was out of 7 marks for the graph)

Thanks

If you just joined up the points then you won't have the correct shape either so I'd say they'd take off 1-2 marks max. It should be a curve that plateaus off at the end.

Oh okay, well I did have the right shape, it plateaued at the end like every secondary source, though it was a bit more jagged I guess you could say.

curve of best fit is needed

I did line of best fit. Hey Adrita, when you use line of best fit/ curve of best fit?
