The superior vena cava is a large, yet short vein that carries deoxygenated blood from the upper half of the body to the heart's right atrium. The inferior vena cava (or IVC) â¦ is the large vein that carries de-oxygenated blood from the lower half of the body into the right atrium of the heart.nferior vena cava is a vein carrying and returning the blood to the heart, and abdominal aorta is an artery taking oxygenated blood from the heart to the various organs and t â¦ issues. 10 people found this useful.
Biochemical differentiation between Staphylococci and Streptococci with CATALASE test: The main criterion for differentiation between Staphylococcus and Streptococcus genera is the catalase test. Staphylococci are catalase positive whereas Streptococci are Catalase negative. Catalase is an enzyme used by bacteria to induce the reaction of reduction of hydrogen peroxide into water and oxygen. III-A.
Quick Introduction. Previously, we investigated how the enzyme catalase increases the rate of hydrogen peroxide decomposition. Remember that catalase binds with hydrogen peroxide (the substrate) at a specific location called the active site.It is this binding that leads to the rapid formation of the products, water and oxygen gas.ools. Enzyme Extraction: You will need to extract enough enzyme so that you can do each control and experimental group three times. The extract may be provided for you by the instructor. Catalase Assay: Refer to the online lab manual and last weeks quick link to refresh your memory about the catalase assay procedure.
