Rohan, Jackson, and Evelyn are conducting a science experiment in their biology class. They are studying the catalase reaction in enzymes. How can they measure the reaction rate for this experiment?

• By observing the amount of O2 formed over time

• By observing the amount of H2O2 formed over time

• By observing the amount of CO2 formed over time

• By observing the amount of H2O formed over time

Benjamin, Arjun, and Lily are conducting a science experiment in their biology class. They are studying the effect of varying the concentration of catalase on the reaction rate. What do they observe as they increase the concentration of the enzyme?

• The reaction rate decreases

• The reaction rate becomes unpredictable

• The reaction rate increases

• The reaction rate remains constant

Luna is studying biology and she came across a concept about enzymes. She learned that the active site of an enzyme has a specific function. What is that function?

• It binds to the substrate

• It releases the product

• It changes the shape of the enzyme

• It is not involved in the reaction

In a science experiment at school, Aiden and Rohan are using filter paper disks. What is the purpose of using these filter paper disks in their experiment?

• To prevent the reaction from occurring

• To measure the reaction time

• To soak up excess catalase

• To hold the catalase solution

Abigail, Grace, and Evelyn are conducting a science experiment in their biology class. They are studying the role of catalase in a potato. What is the role of catalase in this experiment?

• To produce peroxides in the potato

• To detoxify peroxides in the potato

• To speed up chemical reactions in the potato

• To inhibit enzyme activity in the potato

Zoe, Aria, and Abigail are conducting a science experiment in their biology class. They are observing the effect of changing the shape of the active site of an enzyme on the reaction rate. What would happen if they change the shape of the active site?

• The reaction rate decreases

• The reaction rate becomes unpredictable

• The reaction rate remains constant

• The reaction rate increases

Evelyn, Aria, and Mia are conducting a biology experiment. They noticed that when they introduced peroxides into the system, the cells started to behave abnormally. Why do you think this happened?

• Peroxides inhibited the activity of enzymes in the cells

• Peroxides produced harmful by-products in the cells

• Peroxides slowed down the chemical reactions in the cells

• Peroxides damaged the cell membranes

Evelyn, Daniel, and Ava are conducting a science experiment in their chemistry class. They are studying the reaction of catalase with hydrogen peroxide. Can you help them identify the correct chemical reaction that occurs?

• Catalase + O2 --> H2O2 + H2O

• Catalase + H2O2 --> H2O + O2

• Catalase + 2H2O2 --> 2H2O + O2 + Catalase

• Catalase + H2O --> H2O2 + O2

In a science experiment, Luna, Aiden, and Grace are studying the effect of catalase enzyme on the breakdown of hydrogen peroxide. They decide to dilute the catalase enzyme. What could be the purpose of this step in their experiment?

• To decrease the rate at which hydrogen peroxide breaks down

• To prevent the breakdown of hydrogen peroxide

• To increase the rate at which hydrogen peroxide breaks down

• To test the effect of varying enzyme concentration on the reaction rate
