Hydrogen peroxide is a dangerous toxin and therefore can be used to kill bacteria that have entered a wound.

Considering what you know about enzymes which of the following statements describes why it is safe to pour peroxide into a wound to disinfect it.

The liver helps protect the body by removing or changing harmful substances. One substance the body sometimes makes is hydrogen peroxide, which can damage cells if not handled quickly. The liver uses special proteins called enzymes to help with this process.

Why is the decrease in these important enzymes seen in diseases such as NAFLD and cirrhosis so dangerous for the human body?

Beta-Galactosidase is an enzyme that breaks down galactose (a sugar). Whenever galactose is removed from Fluorescein, the molecule glows.

Normally, a certain species of jellyfish glows bright green. However, a small population was moved from the ocean into an aquarium, where the salinity (pH) is lower and can no longer glow.

The jellyfish no longer glow because the enzyme .
