Catalase Experiment Analysis

This video is an update to the catalase experiment using potatoes. It addresses viewer questions and demonstrates the preparation of potato samples, setting up test tubes with hydrogen peroxide, and observing the catalase reaction. The experiment highlights how surface area affects enzyme activity and the impact of boiling and acetic acid on enzyme denaturation.

What is the main purpose of this updated catalase experiment video?

• To demonstrate a different enzyme

• To address viewer questions and comments

• To show a new cutting technique

• To introduce a new experiment

What is the size of the wedge cut from the potato?

• Three centimeters

• Two centimeters

• Half a centimeter

• One centimeter

Why is the video recorded at high speed?

• To make it more entertaining

• To show the knife skills

• To provide a summary of the process

• To save time

What is added to test tube four along with hydrogen peroxide?

• Baking soda

• Salt

• Sugar

• Acetic acid

Which test tube contains the potato that was boiled?

• Test tube 1

• Test tube 2

• Test tube 3

• Test tube 4

What is the role of catalase in the experiment?

• To increase the temperature of the solution

• To change the color of the potato

• To break down hydrogen peroxide into water and oxygen

• To convert water into hydrogen peroxide

How does increasing the surface area of the potato affect the reaction?

• It changes the color of the solution

• It allows more enzyme to contact the substrate

• It has no effect

• It slows down the reaction

Which test tube showed the best results in terms of bubble production?

• Test tube 2

• Test tube 1

• Test tube 3

• Test tube 4

What effect does acetic acid have on the enzyme catalase?

• It enhances the enzyme activity

• It denatures the enzyme

• It has no effect

• It changes the enzyme's color

What is the main conclusion of the catalase experiment?

• All test tubes showed the same results

• Acetic acid enhances enzyme activity

• Increasing surface area increases enzyme activity

• Boiling the potato enhances enzyme activity
