I don't think was the most accurate way of taking the results as there is a lot of room for human error with the shaking of the hand. Why does catalase break down hydrogen peroxide? Mixing hydrogen peroxide with vinegar creates peracetic acid, a corrosive acid that can harm the skin, eyes, nose, throat, and lungs. How does mashing the potato affect the activity of catalase? This activity is due to a special protein produced by the potato to protect itself against oxidative stress. This enzyme breaks down hydrogen peroxide, which is a harmful by-product of the process of cellular respiration if it builds up in concentration in the cells. It must be stored with a stabilizer, such as acetanilide or similar organic materials. . In conclusion, enzyme catalase exhibits low activity at low temperatures 0.
