Whether cortisol is a naturally occurring steroid hormone or a synthetic analog of such has to be predicted. Concept introduction: The families of lipids that have messenger functions are called steroid hormones. It is basically a hormone that is a cholesterol derivative. There are two classes of steroid hormones, sex hormones and adrenocorticoid hormones.

Solution Summary: The author explains that cortisol is a naturally occurring steroid hormone, and that progesterone is an inflammatory hormone.
Chemical pathways by which living things function, especially those that provide cellular energy, such as the transformation of energy from food into the energy of ATP. Metabolism also focuses on chemical pathways involving the synthesis of new biomolecules and the elimination of waste.
