DOES ENZYME COCENTRATION AFFECT ENZYME ACTIVITY?

PLAN

The aim of the following experiment is to determine whether amount of enzyme concentration affects the enzyme activity in an enzyme catalysed reaction.

Hypothesis

Enzyme concentration affects enzyme activity. If this is so, then we should expect a correlation, either positive or negative, between the enzyme concentration and the rate of reaction. Activation energy is needed by every reaction to occur. A high enzyme concentration inevitably increases the rate of reaction. There is a directly proportional ratio (positive correlation) between the two, until a peak rate of reaction occurs where the rate cannot increase any further. This will produce a straight-line graph through the origin, which will eventually flatten off at peak rate.

Scientific Background

An enzyme is a class of protein, which acts as a biological catalyst to speed up the rate of reaction with its substrates. Enzymes have the ability to act on a small group of chemically similar substances. Enzymes are very specific, in the sense that each enzyme is limited to interact with only one set of reactants; the reactants are referred to as substrates. Substrates of an enzyme are
