Chemical Reactions and Enzymes

Front

What is a chemical reaction?

Back

A process where reactants are transformed into products through the breaking and forming of chemical bonds.

Front

What role do enzymes play in chemical reactions?

Back

Enzymes act as catalysts that speed up chemical reactions by lowering the activation energy required.

Front

What does it mean for an enzyme to denature?

Back

Denaturation is the process where an enzyme loses its functional shape due to extreme conditions, such as high temperature or extreme pH.

Front

What is the active site of an enzyme?

Back

The active site is the specific region on an enzyme where substrates bind and undergo a chemical reaction.

Front

What are substrates in the context of enzymes?

Back

Substrates are the reactants that enzymes act upon during a chemical reaction.

Front

What is the significance of the suffix '-ase' in enzyme names?

Back

The suffix '-ase' indicates that the molecule is an enzyme, such as lactase or amylase.

Front

How do temperature changes affect enzyme activity?

Back

Enzymes have an optimal temperature range; too high or too low temperatures can reduce their activity or denature them.

Front

What is activation energy?

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

What is the effect of pH on enzyme activity?

Back

Each enzyme has an optimal pH range; extreme pH levels can denature enzymes and affect their activity.

Front

Can enzymes be reused after a reaction?

Back

Yes, enzymes can be reused multiple times as they are not consumed in the reaction.
