The Peroxides Investigation

Peroxide studies have revealed that peroxides are the wrong name for this enzyme, and the correct term is catalase. It catalyzes the decomposition of hydrogen peroxide. It is present in all somatic cells, especially in highly active hepatocytes.

In my lecture, I will study the reaction of potato enzyme with hydrogen peroxide. In particular, investigate the influence of the change in surface area of ​​potatoes when adding hydrogen peroxide. This is because as the surface area of ​​the potatoes increases, the reaction rate increases as the particles from potato and hydrogen peroxide collide more surface area and the larger the surface area, the more particles carry kinetic energy . By carrying more kinetic energy, the reaction is more likely to achieve its activation energy, thus creating a more successful collision and increasing the rate of reaction through a more successful collision.

The effect of increasing the surface area of ​​the potatoes after mixing with hydrogen peroxide was studied.

In this study, I was asked to study (through experiment) the influence of substrate concentration on the rate of decomposition of hydrogen peroxide catalyzed by hydrogen peroxide. This is part of our research on the enzymatic function, how they work, how the conditions affect the way they work. We have already seen enzyme-substrate complex formation, locking and key model, induction fitting model, activation energy and normal reaction enzyme reaction, balance, specificity and degeneration.

Effect of substrate concentration on decomposition rate of hydrogen peroxide when catalyzed by enzyme catalase

Catalase and peroxidase are heme enzymes that catalyze the reaction of hydrogen peroxide. In the case of 94, 95 catalase, the enzyme reaction is a disproportionation reaction of hydrogen peroxide (reaction 5.82). It seems that its function is to prevent the accumulation of potentially dangerous oxidizing agent. (For molecular oxygen toxicity, see Section III). The X-ray crystal structure of horseradish peroxidase 80 and the high spin iron state of dormancy of horseradish peroxidase 96 have been determined. In both cases, the active site has a hemoglobin b group. In catalase, the axial ligand is a phenolate derived from a tyrosyl residue that binds hemoglobin on the side remote from the active site cavity, water can bind to heme and catalyze in the cavity. The reaction is replaced by hydrogen peroxide. In horseradish peroxidase, the axial ligand is imidazole derived from histidyl residues.
