How Enzymes Function: Effect of Concentration

Vocabulary flashcards covering key concepts, substrates, enzymes, and measurement formulas from the virtual lab simulation on enzyme concentration.

Catalase

The enzyme used in the simulation to investigate how enzyme concentration affects total enzyme activity.

Hydrogen peroxide ($H_2O_2$)

The substrate used in the simulation to react with catalase.

Greater enzyme concentration

Increases the reaction rate because the chance of both collision and binding between substrate and enzyme is increased.

Oxygen

The substance produced as bubbles in each chemical reaction and measured to determine enzyme activity.

Volume of bubbles

Calculated as the total volume of liquid and bubbles minus the volume of liquid (for example, $6.5\,mL - 5\,mL = 1.5\,mL$).
