A single question will be put before each group. It will be the responsibility of the group to design and carry out a study on the assigned subject. The TA will give you help and materials will be made available to you. As in the previous laboratory, it is important that the data be collected carefully. At the end of the laboratory you will present your data and your conclusions to the class.
Most known enzymes are proteins.
The structure and function of a protein is determined by the sequence of its constituent amino acids and the interactions among them. Under conditions that disrupt these interactions, such as extreme temperature, salt concentration and pH, enzyme functions are impaired. Therefore, any enzyme will be effective only within a range of optimal conditions . Delineating these conditions is important in understanding the physiological significance of a given enzyme. This is one of the purposes of this lab.
