AP Bio Enzymes

Front

What is the amount of energy needed for a reaction to occur called?

Back

Activation energy.

Front

How do enzymes relate to the human body's temperature of 98.6 degrees?

Back

Enzymes function best at a specific temperature.

Front

What is the optimal temperature for enzyme activity if it is 30°C?

Back

30°C is the optimal temperature for this enzyme.

Front

With what 3 letters do enzymes typically end?

Back

-ase.

Front

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

Back

Catalyst.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts to speed up chemical reactions.

Front

What happens to enzyme activity at temperatures above their optimal range?

Back

Enzyme activity decreases and can lead to denaturation.

Front

What is denaturation in the context of enzymes?

Back

Denaturation is the process where an enzyme loses its functional shape due to extreme conditions.

Front

What is the relationship between enzyme concentration and reaction rate?

Back

Increasing enzyme concentration generally increases the reaction rate, assuming substrate is available.

Front

What is the function of a substrate in enzyme reactions?

Back

A substrate is the reactant that an enzyme acts upon.
