13. TRUE.
Enzymes are proteins so like every protein enzymes also have optimal temperature and pH at which the activity is maximum the moment we increase or decrease the temperature or pH the enzymes either starts degrading or change in their structure which causes a decrease in their activity.
14. False.
The biochemical test is done to identify the microbes that are being tested. It is mostly done by checking their morphology or how they react to certain stains, In which medium do they grow properly etc.
