Front

What is an enzyme?

Back

A biological catalyst that speeds up chemical reactions in living organisms without being consumed in the process.

Front

Why are enzymes reusable?

Back

Enzymes are not changed by the reactions they catalyze, allowing them to be used multiple times.

Front

What is the role of substrates in enzyme reactions?

Back

Substrates are the reactants that enzymes act upon, transforming them into products.

Front

What is the function of proteins in the cell membrane?

Back

Proteins in the cell membrane facilitate transport, communication, and structural support.

Front

What sugar is primarily found in plant cell walls?

Back

Cellulose is the main sugar that provides structure to plant cell walls.

Front

What is the main function of a cell wall?

Back

To provide structural support and protection to the plant cell.

Front

What is the difference between a substrate and a product in an enzyme-catalyzed reaction?

Back

The substrate is the starting material that undergoes a chemical change, while the product is the result of that change.

Front

How do enzymes lower activation energy?

Back

Enzymes provide an alternative reaction pathway with a lower activation energy, making it easier for the reaction to occur.

Front

What is the significance of enzyme specificity?

Back

Enzyme specificity ensures that enzymes only catalyze specific reactions, preventing unwanted side reactions.

Front

What factors can affect enzyme activity?

Back

Temperature, pH, substrate concentration, and the presence of inhibitors or activators can all affect enzyme activity.
