Question

For an enzymatic reaction, draw curves that show the appropriate relationships between the variables in each plot below.

Short answer

The curves were plotted in a graph for the time vs. product concentration, time vs. enzyme-substrate concentration, and total enzyme concentration vs. initial velocity.

Step-by-step solution

Enzymes

Enzymes are proteins that change therate of a reaction or the pace at which reactants and products combine to generate a product. The rate of enzyme reactions is affected by substrate concentration, pH, and temperature.

Curves plotted for the enzymatic reaction

A. Time vs. Product concentration.

A linear curve is obtained when time is plotted on the X-axis, while product concentrationis plotted on the Y-axis. This is because more reactants generate products as time passes. Thus, the product concentration increases.

B. Time vs. Enzyme-substrate concentration.

The curve has a short climb before saturating when time on the X-axis and enzyme-substrate concentration on the Y-axis is plotted. This is because the active site is already occupied by the substrates, and no additional substrates can be added.

C. Total enzyme concentration vs. initial velocity

A linear curve is obtained when the total enzyme concentration is plotted on the X-axis and the initial velocity on the Y-axis. Initial velocity rises as total enzyme concentration rises because more enzymes are available to accelerate the process ahead.
