The results showed that the molecular weight of the purified enzyme protein was 31. The way we figured this out was by taking four different temperatures and testing the difference absorbance levels they produced every 20 seconds for about 2 minutes straight using a spectrophotometer. When the concentration of the product of an enzymatic reaction is plotted against time, a similar curve results. The substrate causes a conformational change, or shape change, when the substrate enters the active site. In the Unguided modality, we found frequent cases of non‐classic enzyme kinetic behavior due to unsuitable choices for conditions, for instance the enzyme activity being too low to see any change due to unsuitable pH, temperature, etc. References 1 Hata, Tommie S.
