Enzymes

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 is another name for an enzyme?

Back

An enzyme is also known as an organic catalyst.

Front

What is the primary function of enzymes?

Back

The primary function of enzymes is to speed up chemical reactions by lowering the activation energy required.

Front

How do enzymes affect activation energy?

Back

Enzymes lower the activation energy needed to start a reaction, making it easier for the reaction to occur.

Front

What is the enzyme-substrate complex?

Back

The enzyme-substrate complex is the temporary complex formed when an enzyme binds to its substrate.

Front

What role do enzymes play in biological reactions?

Back

Enzymes facilitate and accelerate biological reactions, allowing them to occur at a faster rate.

Front

What is a substrate in the context of enzymes?

Back

A substrate is a reactant molecule that an enzyme acts upon during a chemical reaction.

Front

What is meant by 'induced fit' in enzyme activity?

Back

Induced fit refers to the change in shape of an enzyme when a substrate binds, enhancing the enzyme's ability to catalyze the reaction.

Front

What factors can affect enzyme activity?

Back

Factors that can affect enzyme activity include temperature, pH, substrate concentration, and the presence of inhibitors or activators.

Front

What is an enzyme inhibitor?

Back

An enzyme inhibitor is a substance that decreases or prevents the activity of an enzyme.
