Answer the following question given this paragraph: 

Chemical reactions that consume energy are called endothermic reactions . Energy is usually absorbed from the surroundings as heat. An example is the synthesis of ammonia, described above. In organisms, endothermic reactions are called anabolic reactions . Anabolic reactions construct molecules from smaller units. An example is the synthesis of proteins from amino acids. Endothermic reactions can be represented by the general chemical equation:.
