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:. Q: Chemical reactions that consume energy are called what? A:
Possible answers:
[I] exothermic reactions.
[II] inefficient reactions.
[III] greedy reactions.
[IV] endothermic reactions.
[IV]
