Question

A group of students decided to carry out an investigation to find out how enzyme
activity is affected by temperature changes. They put samples of salivary amylase and
starch into two test tubes. Salivary amylase is an enzyme that breaks down starch
into maltose. Its optimum temperature for activity is around 37°C.

a) What do you think happened to the rate of reaction when they increased the
temperature of the first test tube to 37°C?​

Answer 1

Answer:

At lower temperatures, the enzyme salivary amylase is deactivated and at higher temperatures, the enzyme is denaturated. Therefore, more time will be taken by enzyme to digest the starch at lower and higher temperatures. At 37° C, the enzyme is most active, hence, takes less time to digest the starch.
