This way, the escape of evolved oxygen can be prevented and thus the quantity of oxygen released can be measured more accurately. A stopwatch or any similar device can be used to monitor the time of reaction.

There are even people who mix it with baking soda and use it while brushing their teeth.

However, it's harmful inside your body and must be neutralized. So living with oxygen is necessary, but also dangerous.

As a member, you'll also get unlimited access to over 79,000 lessons in math, English, science, history, and more.

Plus, get practice tests, quizzes, and personalized coaching to help you succeed. In fact your body does produce toxic substances every day.

Catalase can convert this dangerous hydrogen peroxide into water and oxygen gas, thereby protecting your DNA. These amino acids are arranged in a chain to form the protein molecule. Amino acids are like the links; the chain itself is the protein. This is because of how the amino acids chains are folded together. Different organisms will produce slightly different catalases.

For example, the catalase found in animals is slightly different than the catalase found in plants. The folded and twisted segments in this image represent the amino acid chains.

An intensive metabolic activity can be found in soaked pea seeds as they begin to germinate. Role of Catalase in the Red Blood Cells, in prevention of toxicity from hydrogen peroxide.

Hence, their catalytic activity is at higher levels.

Its shape allows the enzyme to bond with a specific substrate (such as hydrogen peroxide).

A substrate is the compound with which an enzyme bonds. In our example, catalase represents the lock, and the hydrogen peroxide represents the key.
