WebDec 17, 2024 · Discussion. To summarize, the amylase at 40 o C had the fastest reaction time as compared to the other temperatures, thus, this is the optimum temperature for amylase. This can be explained as normal human body temperature is 36.8 o C (axillary) (Waugh and grant, 2006). 40 o C is closest to normal body temperature and therefore, the … WebThe optimal temperature of amylase would be 87°C because that’s the degree at which starch was broken down the fastest. Enzymes inside the body are said to function better at the optimal temperature of 37˚C, so the fact that our enzyme functioned better at 87˚C doesn’t support that.
