Welcome!Today we'll explore monomers, polymers, condensation, and hydrolysis. These are key concepts in A-level Biology, so let's learn step by step!
What are Monomers and Polymers?Monomers are small, basic molecules that can join together to form larger molecules. Polymers are long chains of monomers chemically bonded together. This process is crucial in forming biological molecules like proteins and carbohydrates.
Which of the following is a monomer?

Condensation and HydrolysisCondensation is a chemical reaction that joins monomers together to form polymers, releasing water as a by-product. Hydrolysis is the opposite process, where water is used to break polymers back into monomers.
Why are these reactions important?Condensation builds essential molecules like proteins and DNA, while hydrolysis breaks them down during digestion to release energy and nutrients.
During condensation reactions, monomers join together and release {{blank0}} as a by-product.
