2. The mechanism of HMG-CoA reducatse enzyme activity involves several stages. For the catalytic reaction to proceed, another substrate known as NADPH, which acts as a reducing agent is required. The kinetics of enzyme activity with NADPH at non-limiting amounts of HMG-CoA in the absence or presence of compactin is shown below. a) Based on the description above, which of the six types of enzymes does HMG-CoA reductase belong to? b) What is the Km for the reaction with no inhibitor present? Do NOT forget the units. Answers can be expressed either as a fraction or in decimals. c) What happens the measured Km with increasing amounts of compactin?
