Learn: Monomers, Polymers, Condensation and Hydrolysis

Welcome!Today, we're going to explore Monomers, Polymers, Condensation and Hydrolysis. These are essential concepts in A-level Biology and will help you understand how biological molecules are formed and broken down. Let’s dive in!

What are Monomers and Polymers?Monomers are small, basic molecules that can join together to form larger molecules called polymers. Polymers are long chains made by linking many monomers together. These are crucial for creating larger biological molecules like proteins, carbohydrates, and nucleic acids.

What is Condensation?Condensation reactions occur when two monomers join together to form a polymer. During this process, a molecule of water is removed. For example, when two glucose molecules bond to form maltose, a water molecule is released.

What is Hydrolysis?Hydrolysis is the process where a polymer is broken down into its monomers by adding water. This reaction is the reverse of condensation. For example, water can break down maltose into two glucose molecules.

Why are Condensation and Hydrolysis Important?These reactions are essential in living organisms. Condensation builds complex molecules needed for growth and repair, like proteins and carbohydrates. Hydrolysis breaks them down during digestion, releasing smaller molecules that can be absorbed and used by cells.
