    Controlled Reactions 1) Describe the relationship between substrate concentration and the initial reaction rate of an enzyme-catalyzed reaction. Is this a linear relationship? What happens to the initial reaction rate as substrate concentration increases? A) The relationship between the substrate concentration...

    60-120 intervals. 3. Did your enzyme's rate change over time? How does this compare to a real enzyme? The enzyme’s rate did change over time. This compares to a real enzyme because an enzyme’s job is to speed up the reactions and as time allotted. That did happen since the enzyme in our lab was able...

    up the rate of a chemical reaction. Because they regulate the rate of chemical reactions, they are also called catalysts. There are many, many different types of enzymes, because for each chemical reaction that occurs, an enzyme specific to that reaction must be made. To act on a substrate, an enzyme...
