10. Catalase is an enzyme that breaks down hydrogen peroxide into water and oxygen. A solution containing catalase would show a positive result when: * O The solution is tested using the grease spot test O Biuret's reagent is added to the solution O Ninhydrin is added to the solution O Lugol's lodine is added to the solution O Benedict's reagent is added to the solution O This is a required question

Look at the nutritional content of lactase milk. Lactose is an enzyme that breaks down the milk sugar lactose. For people who are lactose intolerant, lactase milk is more digestible. What can you conclude about the contents of lactose milk? Multiple Choice O Adding lactose increases the grams of sugars present compared to whole milk O C Although the lactase breaks down the disaccharide lactose, monosaccharides are still present O Adding lactase removes most of the sugar from the milk....

1. You have a stock solution of 35 % hydrogen peroxide. You need to make several dilutions for a reaction. Calculate how much volume of the stock hydrogen peroxide you need to make 50 mL of 10 % hydrogen peroxide. 2. Using the equation of the line from the graph below, calculate the concentration of hydrogen peroxide if 820 mL of foam is produced from the reaction with potassium iodide. Foam Production vs. Concentration H2O2 1500 y 49.534x R-0.9677 1000...

Dr. Waters found an old bottle of dilute hydrogen peroxide in her refrigerator and needs your help in determining the percent hydrogen peroxide that still may be present. She knows that by keeping the hydrogen peroxide cold and in the dark that it will have a longer shelf-life. But she has moved several times and does not know how old the dilute hydrogen peroxide is that remains. We are providing you with a standardized solution of potassium permangangate of 0.1057...

Some bacteria can excrete a toxin that breaks down sphingomyelin in mammalian erythrocytes, causing those red blood cells to lyse. Examination of the toxin showed it to be an enzyme that could break the phosphoester bond between sphingosine and phosphocholine (ie. the products are ceramide and phosphocholine). The mechanism of the reaction is as follows: The active site of the enzyme contains three critical residues—histidine 296, glutamate 53 and histidine 151. The glu positions a Mg+2 ion near the phosphate....

I need to: DETERMINE THE CONCENTRATION OF HYDROGEN PEROXIDE IN THE SOLUTION how ?? THEORY Titrimetry, or titrimetric analysis, is an example of a so-called classical method of analysis. Titrimetry is a convenient method of getting very small amounts of chemicals in to a reaction because the method involves the use of dilute solutions of reactants. Hydrogen peroxide reacts with potassium iodide according to the reaction given below: HB2BOB2B + 2HP+P + 2IP-P = IB2B + 2HB2BO (equation...

When a cell breaks down glucose to produce ATP lots of hydrogen ions are produced. When a lot of hydrogen ions are present in a solution, that solution is an acid. If a lot of acid is present a cell would die. How does a living cell get rid of all the hydrogen ions that id produces while making ATP? It combines the hydrogen ions with oxygen to make water. It uses the hydrogen ions to produce the carbon dioxide...
