In order for the human body to function properly, it must maintain systemized conditions to preserve and manage an internal environment that exists to adapt or fight extrinsic situations. Many different processes occur to create this internal stability, all important and of different use; that being said, enzymes are proteins that act as catalysts and affect the rate of biochemical reactions by reducing the amount of energy needed to begin the reaction and speeding up the process to ensure it happens at a rate useful to human life and routine. There are hundreds of different enzymes in your cells, each responsible for specific reactions. The one studied in this lab is catalase, which accelerates the breaking down of the toxic chemical hydrogen…show more content…
The reaction was somewhat impressive, producing a considerable amount of foam in the process, and was concluded to be about a 4 on the scale. Another piece of liver was added to the now used peroxide, and the reaction was insignificant; there was little to no reaction at all (about a 1). The tainted peroxide was then transferred to an empty test tube, and 2 ml of H2O2 was added to the remaining liver, having about the same reaction as the untainted liver and H2O2 that was first tested (4); because the H2O2 had already been broken down into water and oxygen, the reaction was small, as there was nothing for the catalase to perform its job on. This proved that catalase is definitely reusable; if it weren’t, the human body would not be able to function…show more content…
2 ml of clean H2O2 was added to 3 test tubes; potato, apple, and chicken joined. The chicken had the greater reaction (2), while the apple (.5) and potato (1) had produced a miniscule amount of reaction to be observed. While they all contained catalase, chicken had more; animal tissues require the need for catalase on a stronger level to maintain that internal
