Polymers

Mr. Anderson explains polymers, large molecules made of monomers, using examples from biology like cellulose and proteins. He describes polymer formation through dehydration reactions and breakdown via hydrolysis. The video includes a practical example of digestion, where polymers in food are broken down and reassembled in the body. The lesson concludes with a personal anecdote, emphasizing the importance of polymers in everyday life.
