I’m really stuck on how to approach this lab report for my biology class. We did an experiment on enzyme reaction rates, and I recorded all the data, but I’m not sure how to organize the analysis section to properly show the relationship between substrate concentration and the initial velocity.

I felt the same way, and then I just dumped the data into a quick scatter plot of initial velocity versus substrate concentration. Seeing the hyperbolic curve helped me stop trying to force a straight line and instead describe the trend and where it starts to saturate.

I kept the initial velocity as the early slope in each trial, measured as the change in signal per unit time, to compare across concentrations.

We tried fitting a Michaelis-Menten curve in the analysis but the data was noisy at high concentrations, so the parameters were unstable and I abandoned the fit midway.

Do you think the problem is the data quality rather than the concept?

I drafted the analysis section as a narrative: surface trend, then possible mechanistic interpretation, and then mention limitations. I kept numbers in a table but the writing felt awkward.

We did notice a plateau around mid-range concentrations, which a line wouldn't capture, so I described that as saturation in the report.
