Question

___ is defined as the production of a substance by the coming together of chemical elements, groups, of simpler compounds or by the degradation of a complex compound where simple molecules are built larger and more complex

Answer 1

Anabolism is a chemical reaction where smaller, simpler molecules are assembled into larger, complex substances using energy, contrasting with decomposition reactions where compounds break down into simpler substances. A combination (composition) reaction also describes the formation of a single compound from multiple reactants.

Step-by-step explanation:

The process described in the question is known as anabolism, which refers to chemical reactions where smaller, simpler molecules are combined to create larger, more complex substances. This process involves the use of energy to form compounds vital to living organisms. An example of anabolism is the synthesis of proteins from amino acids in the human body. Anabolism is a subset of metabolism, which also includes catabolism, the breaking down of complex substances into simpler ones.

Contrastingly, a decomposition reaction is the opposite of anabolism. It involves a compound breaking down into two or more substances, which can be elements, other compounds, or a mixture of both. This reaction can be seen in processes such as the breakdown of hydrogen peroxide into water and oxygen gas.

A combination (composition) reaction is similar to anabolism in that it forms a single compound from two or more reactants. However, the term is used more broadly in chemistry to include any reaction where multiple substances combine, regardless of complexity, such as the formation of water from hydrogen and oxygen gases.
