Enzyme Reactions with Hydrogen Peroxide

The video demonstrates what happens when blood is mixed with hydrogen peroxide. Blood contains an enzyme that reacts with hydrogen peroxide, resulting in the formation of water and oxygen. This reaction causes bubbles to form, which are visible as oxygen is released.

What is the initial step in the experiment discussed in the video?

• Mixing water with hydrogen peroxide

• Mixing sugar with hydrogen peroxide

• Mixing blood with hydrogen peroxide

• Mixing salt with hydrogen peroxide

What does the enzyme in blood do when it comes into contact with hydrogen peroxide?

• It turns into a solid

• It reacts to form water and oxygen

• It evaporates

• It changes color

What is the role of the enzyme found in blood during the reaction?

• It has no effect on the reaction

• It prevents the reaction

• It slows down the reaction

• It acts as a catalyst to speed up the reaction

Which of the following is a product of the reaction between blood and hydrogen peroxide?

• Oxygen

• Carbon dioxide

• Nitrogen

• Helium

Why do bubbles form during the reaction between blood and hydrogen peroxide?

• Due to the release of helium

• Due to the release of oxygen

• Due to the release of carbon dioxide

• Due to the release of nitrogen
