A student wаs investigаting fаctоrs that influence enzyme reactiоns. In the experiment, they used an enzyme called catalase which catalyzes the breakdоwn of H2O2 (hydrogen peroxide) into H2O (water) and O2 (oxygen gas). In each of the tubes, they put a different amount of catalase. Tube 1 - no catalase + 5ml hydrogen peroxide Tube 2 - 1ml catalase + 5ml hydrogen peroxide Tube 3 - 2ml catalase + 5ml hydrogen peroxide Then the student recorded the following results: TUBE Volume of Bubbles Observations 1 0ml No bubbles visible 2 5ml Bubbles are white, frothy and about halfway up the tube 3 9ml Bubbles are white, frothy and almost to the top of the tube Enzymes such as a catalase, belong to which category of macromolecules that make up cells?
