Factors Affecting Enzyme Act 2

Get involved in learning with highly interactive and engaging science activities. It’s all about doing and becoming an active participant in your own learning. The time is now, so get started and see where it takes you.

Using the human digestive system as an example, learn how two enzymes—pepsin and peptidase—function best at a specific pH. To do so, you’ll have to test their enzymatic activity in the lab using egg whites and solutions of varying pH levels.

• Discover how pH affects enzymatic activity.
• Experiment with two digestive enzymes to determine the pH at which they work best.
• Make hypotheses and analyze the results of your experiment.
• Graph your observations of the effect of pH on enzyme activity.
• Explore how the optimum pH for digestive enzymes relates to their location in the human body.

App features:
• Investigate enzyme activity in a virtual lab.
• Set up and perform your own experiments on enzymes.
• Make predictions and draw conclusions from data.
• Test your knowledge by completing a short quiz.
