Read this paragraph and choose the correct option from the provided answers:

Water is an essential part of most metabolic processes within organisms. Metabolism is the sum total of all body reactions, including those that build up molecules ( anabolic reactions ) and those that break down molecules ( catabolic reactions ). In anabolic reactions, water is generally removed from small molecules in order to make larger molecules. In catabolic reactions, water is used to break bonds in larger molecules in order to make smaller molecules.

 Choices:

- respiration

- growth

- immunity
