MCAT Biology Section
Three Key Concepts Tested
Foundational Concept 1: Biomolecules have unique properties that determine how they contribute to the structure and function of cells, and how they participate in the processes necessary to maintain life.
- 1A: Structure and function of proteins and their constituent amino acids
- 1B: Transmission of genetic information from the gene to the protein
- 1C: Transmission of heritable information from generation to generation and the processes that increase genetic diversity
- 1D: Principles of bioenergetics and fuel molecule metabolism
Foundational Concept 2: Highly-organized assemblies of molecules, cells, and organs interact to carry out the functions of living organisms.
- 2A: Assemblies of molecules, cells, and groups of cells within single cellular and multicellular organisms
- 2B: The structure, growth, physiology, and genetics of prokaryotes and viruses
- 2C: Processes of cell division, differentiation, and specialization
Foundational Concept 3: Complex systems of tissues and organs sense the internal and external environments of multicellular organisms, and through integrated functioning, maintain a stable internal environment within an ever-changing external environment.
- 3A: Structure and functions of the nervous and endocrine systems and ways in which these systems coordinate the organ systems
- 3B: Structure and integrative functions of the main organ systems
