A solution of an enzyme normally found in the human body was added to a flask containing a solution of proteins in distilled wat
xenn [34]
<h3><u>Answer;</u></h3>

increase the temperature from 27 degrees celsius to 37 degrees celsius

<h3><u>Explanation;</u></h3>
  • The rate of an enzyme-catalyzed reaction increases as the temperature is raised.
  • <em><u>The human body is maintained at 37°C as this is the temperature at which the enzymes in our body work best. Therefore increasing the temperature from 27 degrees Celsius to 37 degrees Celsius increases enzyme activity and in turn increases the production of amino acid in the flask.</u></em>
  • Higher temperatures than 37° C which is the optimum temperature, disrupt the shape of the active site, which will reduce enyzme activity, or prevent it from working, in other words the enzyme will have been denatured.
