Enzyme Reaction Rates

These flashcards cover key terms and concepts related to enzyme reaction rates, their measurement, and related variables.

Enzyme Reaction Rate

The amount of reaction per unit time, often expressed in terms of time-1.

Catalase

An enzyme that catalyzes the breakdown of hydrogen peroxide (H₂O₂) into water (H₂O) and oxygen (O₂).

Enzyme-Substrate Complex

The transient complex formed when an enzyme binds to its substrate.

Rate of Disappearance

Measuring the time it takes for a substrate, such as H₂O₂, to be consumed in an enzymatic reaction.

Rate of Appearance

Measuring the time it takes for a product, such as O₂, to be produced in an enzymatic reaction.

Reaction Rate Calculation

The reaction rate can be calculated by measuring the volume of gas produced over a specific time period.

Scatterplot with Trendline

A graphical representation showing the relationship between two variables, with a trendline indicating the overall direction of data.

Manipulated Variable

The variable that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

Independent Variable

The variable that is manipulated to determine its effects on the dependent variable.

Dependent Variable

The variable that is measured or tested in an experiment.
