Enzymes

Front

What are enzymes?

Back

Enzymes are biological catalysts that speed up chemical reactions in living organisms without being consumed in the process.

Front

What type of molecule are enzymes primarily made of?

Back

Enzymes are primarily made of proteins.

Front

What is the role of the active site in an enzyme?

Back

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

Front

What is a substrate in the context of enzymes?

Back

A substrate is the reactant molecule that an enzyme acts upon.

Front

What is the enzyme-substrate complex?

Back

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

Front

What does it mean for an enzyme to be specific?

Back

Enzymes are specific, meaning each enzyme typically catalyzes only one type of reaction or works on a specific substrate.

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 happens to an enzyme when it is denatured?

Back

When an enzyme is denatured, its structure is altered, and it can no longer function properly.

Front

What is an inhibitor in relation to enzymes?

Back

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

Front

What is an activator in relation to enzymes?

Back

An activator is a substance that increases the activity of an enzyme.
