Condensation reaction

The video explains condensation reactions, where smaller molecules like water are eliminated. It highlights the formation of large biological molecules through these reactions. Plants create starch by joining glucose molecules, eliminating water each time a glucose is added to the chain.

How are glucose molecules joined together in the formation of starch?

• By hydrolysis

• By condensation reactions

• By oxidation

• By fermentation

What happens each time a glucose molecule is added to the starch chain?

• A water molecule is added

• A water molecule is eliminated

• A carbon molecule is added

• A nitrogen molecule is eliminated
