What can contamination of reagents leads to? Unreliable results Reliable results Reproducible results Good results Catalase is the enzyme found in potatoes and It decomposes hydrogen peroxide (H202) to form water and oxygen gas. H202 + catalase - ----> H2O + 02 +E. The reaction is maintained at temperature 40 degree Celsius and there was a formation of bubbles. Based on the enzymatic reaction given, What do you think is the substance responsible for the formation of bubbles? Oxygen gas Hydrogen gas no reaction, because the enzyme catalase will be deactivated no reaction, because the enzyme catalase will be denatured Other: Based on the Fehling's test video, do you think the sugars ribose (in RNA) and the deoxyribose (in DNA) will both form a positive result (red precipitate) No Yes
