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.
AIM: I aim to find the rate of reaction between catalase and hydrogen peroxide. Enzymes such as Catalase are protein molecules that are found in living cells. They are used to speed up specific reactions in the cells. Each enzyme just performs one particular reaction so they are all very specific. Catalase enzymes found in living cells e.g. in yeast, potato or liver, speed up (in our case) the breaking down of hydrogen peroxide. The lock and key analogyâ¦. The lock is the enzyme and its active sight is where you put the key in. The key is like the substrate that comes and bonds to the active site or the key that fits into the lock. [pic]. The collision theory. The collision theory explains rates of reaction in terms of the motion of particles in the reactants.
