Homework Answers
Answer: Spinach
Among vegetables there are many of them are a good sources of catalase among them spinach is also one of them. Others ares broccoli, zucchini, carrots, cucumber, avacado etc. the spinach aslo contain other enzymes such as DPNH-glyoxylate reductase and glycolate oxidase.
Apples: It contains very least amount of catalase. While the apples are put in the peroxide it produces only few bubbles.
Yeast solution: The main source of enzyme called zymase which are responsible for the production of carbon dioxide and ethanol from sugar fermentation. The yeast contain mainly two types of enzyme called invertase ans maltase
Wheat germ: These have a lipase enzymatic activity which result in the shelf life reduction.

In a sample, you used 0.5 g of wheat germ in 5 ml of enzyme extraction buffer (total volume of 5.5 mL). After homogenization and centrifugation,you used a 250 µl aliquot of the wheat germ extract to determine the amount of acid phosphatase present. You found that 3.2 µg of acid phosphatase was present in the 250 µl aliquot. First off, what is the concentration of acid phosphatase in your extract? 12.8 ug/uL 0.0128 ug/uL 0.00058 ug/uL 0.5 ug/mL How...

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

1 of 1 Part D-A typical enzyme experiment A common enzyme studied in many introductory biology labs is catalase, which is found in high concentration in most cells, promoting the decomposition of hydrogen peroxide (H2O2) Hydrogen peroxide is formed as a by-product of chemical reactions and would soon kill cells if not immediately removed or broken down into its products--water and oxygen-as shown by the following equation Catalase 2 H2O, → 2 H2O + 0, You may be familiar with...

The researchers set up the following experiment: 1. Each yeast strain is diluted in phosphate buffer solution so that there is the same concentration 2. Lysis buffer, which dissolves the cell membrane and releases the cytosol into the solution, is 3. ONPG is added to each tube. After 15 minutes, the researchers use a spectrophotometer to 4. The Ago is used to calculate the Activity Units of each tube, measured in velocity/mL. Activity of cells in each tube....
