4. What was the independent variable in the "Effect of Temperature on Enzyme Activity" lab?
5. What was the dependent variable in the "Effect of Temperature on Enzyme Activity" lab?
Homework Answers
4. Independent variable- temperature as it is constantly changed during the experiment to check its effect on Renin. The temperature used was 200 C, 300 C, 400 C and 500C.
5. Dependent variable- enzyme activity or rate of reaction is dependent on the temperature. the enzyme Renin curdles the milk. Thus on which temperature its activity is maximum is noted down. Its activity is assessed by the time it takes to curdle the milk. The less time it takes the more active the enzyme is on that particular temperature.

Enzymes Temperature is an important factor that can regulate enzyme-mediated functions. Temperature is one of the tightly homeostatically controlled variables in the human body. What are the symptoms of loss of temperature control during a high fever? Explain why these symptoms occur based on enzyme function and cell signaling effects that are dependent on temperature. Based on Figure 1, explain how the temperature optimum of the activity of enzymes is expected to differ in organisms depending on where they live....
