Enzyme E Is Responsible for Conversion of Substrate X to Product

question 27

Multiple Choice

Enzyme E is responsible for conversion of substrate X to product U.As a result of this conversion electrons are transported to a coenzyme (FAD) within Enzyme E.In order for the reaction to be completed, a second substrate NAD⁺ must also bind Enzyme E and collect stored electrons (which converts it to product, NADH) .The graph below shows the data while varying X, with fixed concentrations of NAD⁺.What type of multi-substrate mechanism does enzyme E utilize?

• A)sequential - Ordered
• B)sequential - Random
• C)simultaneous addition
• D)Ping Pong
