Worked Solution & Example Answer:Six students performed a trial experiment on enzyme activity - HSC - SSCE Biology - Question 22 - 2011 - Paper 1
Step 1
What is the purpose of this experiment?
Answer
The purpose of this experiment is to investigate the effects of enzyme activity on a cloudy suspension and to determine how factors such as enzyme volume, temperature, pH, and time influence the enzyme's ability to break down the suspension into a clearer solution.
Step 2
Describe TWO changes that would improve the validity of the data collected in the experiment.
Answer
-
To improve the experiments' validity, consistency in temperature should be maintained throughout all trials to ensure that temperature fluctuations do not influence enzyme activity.
-
A control sample should be included, which does not contain the enzyme solution, allowing for a direct comparison to better assess the enzyme's effectiveness.
