Front

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

Back

The shapes of the enzyme are altered (denatured).

Front

What is a substance called that speeds up a chemical reaction?

Back

Catalyst

Front

Can an enzyme be used only once in a chemical reaction?

Back

False, enzymes can be reused.

Front

What causes a decrease in enzyme activity?

Back

The enzyme has become denatured.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts to speed up chemical reactions.

Front

What is denaturation in the context of enzymes?

Back

Denaturation is the alteration of an enzyme's shape, affecting its function.

Front

What factors can affect enzyme activity?

Back

Temperature, pH, and substrate concentration.

Front

What is the optimal temperature range for most human enzymes?

Back

Approximately 37 degrees Celsius (98.6 degrees Fahrenheit).

Front

What is a coenzyme?

Back

A coenzyme is a non-protein molecule that assists enzymes in catalyzing reactions.
