Step-by-step explanation:
Dehydration Synthesis : Two monosaccharides (simple sugars) are joined together to form a disaccharide (double sugar) molecule. During this reaction, a molecule of water is removed, and a covalent bond is formed between the two monosaccharides. One monosaccharide loses a hydroxide group (-OH) from its carbon atom, while the other monosaccharide loses a hydrogen ion (H+), and the two react to form a covalent bond between the two carbon atoms. This process requires energy to occur.
Hydrolysis : Opposite process of dehydration synthesis, and it is the chemical reaction by which a disaccharide is broken down into two monosaccharides. During hydrolysis, a molecule of water is added to the disaccharide, causing the covalent bond between the two monosaccharides to break. One monosaccharide molecule gains a hydroxide group (-OH), while the other gains a hydrogen ion (H+), which were previously lost during dehydration synthesis. This process releases energy in the form of ATP
