Enzymes

Front

What are enzymes?

Back

Enzymes are proteins that act as catalysts to speed up chemical reactions in biological processes.

Front

What is the role of a substrate in enzyme activity?

Back

A substrate is the specific reactant that an enzyme acts upon to produce a product.

Front

What happens to enzymes at high temperatures?

Back

Enzymes can denature, meaning their shape is altered, which affects their ability to function.

Front

What is a base in terms of pH?

Back

A base is a substance with a pH greater than 7.

Front

What is the product of an enzyme-substrate reaction?

Back

The substrate becomes a product after the enzyme catalyzes the reaction.

Front

Can enzymes act on multiple substrates?

Back

No, enzymes are specific to their substrates and typically act on one type of substrate.

Front

What is denaturation in enzymes?

Back

Denaturation is the process where an enzyme's structure is altered, preventing it from functioning properly.

Front

What are the four main types of biological macromolecules?

Back

Proteins, nucleic acids, lipids, and carbohydrates.

Front

How do enzymes lower activation energy?

Back

Enzymes provide an alternative reaction pathway with a lower activation energy, making it easier for reactions to occur.

Front

What is the active site of an enzyme?

Back

The active site is the region on the enzyme where the substrate binds and the reaction occurs.
