Predict which temperature 20 degrees Celsius, 39 degree Celsius, 50 degree Celsius you would expect a human to function best. Plan a simple investigation to test your hypothesis

39 degree Celsius

Explanation:

Human body functions well at 36 degree Celsius. All the body functions and the enzymes secretion and processes works best on the temperature 36 degree Celsius.

The enzyme of humans will function good on temperature 39 as it is the very near to the body temperature of the human. The optimal temperature would be between temperature 35 to 40 degrees for most of the enzymes.

Testing hypothesis :

Add amylase which is an enzyme present in the saliva to a concentration sugar, which acts as the reactant in a small container having a lid. Use a thermometer to mark the changes in the temperature. We have to take two identical samples of our experiment. Place one sample at a room temperature of 25 degree Celsius and the other to be heated to 40 degree Celsius. Now we have to check the concentration of the product for each temperature. And while checking the sample which is heated, we see that at some point, the rate where the substrate is being converted in to product  decreases as the enzyme denaturation and the reaction will stop. The optimal temperature is the one where the product is produced at the maximum rate.
