Biomolecules
Biomolecules are carbon-based molecules made by living things. The four categories of biomolecule - proteins, lipids, nucleic acids and carbohydrates - compose living things and carry out their chemical processes.
Cellular energetics
Cellular energetics is the study of how cells transform energy needed for biological function by coupling energy-releasing reactions with energy-absorbing reactions. Though many bodily processes involve energy transformation, some crucial examples include cellular respiration, photosynthesis and ATP phosphorylation.
Chemical Principles
Chemical principles are the fundamental rules explaining the behavior, composition and interactions of matter. Chemical reactions arise from attraction/repulsion forces between particles such as atoms or molecules - the building blocks of all matter.
Drug development
Drug development is an applied science in which new drug compositions are created, tested, and possibly made available for use. This process provides regulated drug development pathways that include testing by in vitro, in vivo and clinical trials.
Metabolism
Metabolism refers to all 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.
