This rate is called the initial rate of reaction. 8 Various factors aff ect the rate of activity of enzymes. Four important factors are enzyme concentration, substrate concentration, temperature and pH.
- The enzyme I will be using will be potato catalase. I will be using two types of potatoes, an old potato and a new potato and hence I will investigate whether the age of a potato has an effect on the catalase concentration and hence the rate of reaction.
- Enzyme activity can also be affected by surface area, ie. the more enzyme exposed to substrate or the more substrate exposed to enzyme.. For example, if potato cells are crushed or cut into smaller pieces, this may affect how much catalase enzyme comes into contact with substrate (H2O2).
- difference in enzyme activity at the time of divergence (16 minutes). The assay samples with added lactose, however, showed an immediate decline in enzyme activity at 16 minutes. An immediate decrease is consistent with the hypothesis that a competition effect influenced the enzyme assay in whole or in part.
- The purpose of a purification table is to monitor the progress of the enzyme purification. Both yield and relative purity of the enzyme are calculated, taking advantage of protein concentration and enzyme activity experimentally determined for each fraction. First we must transfer the data from table 3 and 4 into the purification table.
- An enzyme is supposed to speed up the reaction, but our observations shows that the concentration of the substrate also had an effect on how fast the reaction could occur. When there was zero concentrate of hydrogen peroxide, meaning the solvent was only water, there was no reaction with the catalase.
