Final answer:
Dehydration synthesis and hydrolysis are chemical reactions that involve the creation or consumption of water. Dehydration synthesis combines molecules and releases water, while hydrolysis breaks down molecules with the addition of water. Water plays a key role in both processes.
Step-by-step explanation:
Dehydration synthesis and hydrolysis are two types of chemical reactions that involve the creation or consumption of water. In dehydration synthesis, two molecules combine to form a larger molecule, and in the process, a molecule of water is released as a byproduct. This reaction is important in the synthesis of macromolecules such as proteins and carbohydrates. On the other hand, hydrolysis is the opposite of dehydration synthesis, where a larger molecule is broken down into smaller molecules by the addition of water. Hydrolysis is involved in the digestion of macromolecules in the body. Water plays a crucial role in both processes, as it is either released or consumed in the reactions.
