Enzymes

Front

What is a substance called if it speeds up a chemical reaction?

Back

Catalyst

Front

What is the optimum pH of the enzyme if the graph indicates a peak at 6.6?

Back

The optimum pH of the enzyme is 6.6.

Front

What happens to enzymes when they are heated to a high temperature?

Back

The shape of the enzyme is changed and it denatures.

Front

Why are enzymes considered reusable?

Back

Enzymes are not changed when they catalyze a chemical reaction.

Front

Which statement is NOT true about enzymes?

Back

Enzymes can only be used once in a chemical reaction.

Front

What is denaturation in the context of enzymes?

Back

Denaturation is the process where an enzyme loses its shape and functionality due to external factors like heat or pH.

Front

What factors can affect enzyme activity?

Back

Temperature, pH, and substrate concentration can all affect enzyme activity.

Front

What is the role of a substrate in enzyme activity?

Back

A substrate is the reactant that an enzyme acts upon to catalyze a chemical reaction.

Front

How do enzymes lower the activation energy of a reaction?

Back

Enzymes provide an alternative reaction pathway with a lower activation energy.

Front

What is the active site of an enzyme?

Back

The active site is the specific region of the enzyme where the substrate binds.
