View lab report - biology 1010 lab report enzymes from bio 101 at tri-county technical college the effects of ph and enzyme concentration on catecholase activity emily outen biology 101-008 june 10,. Catecholase catalyzes the reaction rate of catechol oxidation catechol is found beneath the skin of many plants such as apples and potatoes when it is exposed to air, the oxygen in the atmosphere oxidizes it to benzoquinone, which acts as an antiseptic for the plant. Catechol is this enzymes substrate which will separate from the catecholase in intact cells (walker,1995) however, damaged cells form an additional substance this substance is formed when the two come into contact and catalyzes is the substance defined as benzoquinone. Catecholase does this by catalyzing a reaction among catechol and oxygen, in which catechol is oxidized to benzoquinone and oxygen is reduced to water hypothesis: the accumulation of catecholase (an enzyme) to catechol (substrate) will result in the creation of benzoquinone.

The enzyme catecholase and substrate catechol separate from each other in intact cells however, whenever the cell is damaged, they come in contact with one another which produces the formation of benzoquinone, which is a brown substance. The oxidation of catechol by tyrosinase tion of enzyme i was 41 catecholase units per 3 ml and the concentration of enzyme ii wee 39 catecholase units per 3 ml . Factors influencing the catecholase activity and inactivation of tyrosinase the effect of gelatin and of catechol concentration a partially purified enzyme was . The effect of ph on enzyme activity the effect of ph on function of catecholase enzyme in potato abstract in biochemical reactions, enzymes activity could be changed based on these factors. Catechol (substrate) and catechol oxidase are both present in potatoes, however, do not come in contact with one another unless the tissue of the vegetable has been damaged or harmed in some way this rotting, or browning, is a reaction that occurs because when oxidation occurs, the catechol becomes benzoquinone (brunson, 2015).

When the substrate combines with the catecholase enzyme of a potato, the product is a reddish brown color called benzoquinone this product is what turns fruits and vegetables brown (briggs and others 2010). Enzyme reactions: discussion and results the higher the concentration of catechol, the more benzoquinone that can be produced the effect of enzyme .

In this experiment, the effect of varying ph, temperature, and enzyme and substrate concentration on the activity of the enzyme catecholase was investigated the activity of the enzyme was measured by testing the absorbance, which is a measure of the formation of benzoquinone.
