Answer the following question given this paragraph: 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 catabolic reactions, water is used to break bonds in larger molecules in order to make smaller molecules. Q: What is the sum total of all body reactions? Choices: - respiration - growth - immunity - metabolism A:
(A).
metabolism
