which of the following was the substrate used in the enzymes lab?

○ oxygen (o₂)
○ hydrogen peroxide (h₂o₂)
○ catalase
○ isopropyl alcohol
○ ph solutions / buffers
○ water (h₂o)

Explanation:

Enzymes are biological catalysts. The substrate binds to a specific region on the enzyme called the active site. In enzyme - lab experiments, hydrogen peroxide (\(H_2O_2\)) is a common substrate. Catalase is an enzyme that acts on hydrogen peroxide. Oxygen (\(O_2\)) is a product of the decomposition of hydrogen peroxide by catalase. Isopropyl alcohol is not a substrate for the catalase - hydrogen peroxide reaction. pH solutions/buffers are used to maintain the pH of the reaction environment. Water (\(H_2O\)) is also a product of the decomposition of hydrogen peroxide.

Answer:

For the first question: Active Site.
For the second question: Hydrogen Peroxide (\(H_2O_2\)).
