HSC Biology Assessment Task 1 – Enzyme Activity

Introduction:
Enzymes are biological catalysts that regulate and accelerate the rate of biochemical reactions within a cell, but are not used up or changed in those reactions, therefore are accessible for reuse. They allow reactions to occur at a lower temperature than would otherwise be necessary in their absence. However, almost every significant life process is dependent on enzyme activity and without them life would cease. Enzyme activity occurs on chemical substances known as a substrate. Enzymes cannot force chemical reactions to occur, they can only increase the speed of reactions. The roll of an enzyme is to ensure that a reaction can occur without abnormal increases in body temperature. They require specific conditions in which to work and this is varied depending on the enzyme, they also have optimum levels of temperature and pH. Substrate concentration is another factor that could affect the activity of an enzyme and thus the result of a reaction.
