The Biological and Biochemical Foundations of Living Systems section of the MCAT® explores how cells, tissues, and organ systems work together to maintain life. This section emphasizes foundational knowledge of biology and biochemistry, focusing on the processes that allow organisms to grow, respond to stimuli, and maintain internal balance.
Key topics covered include:
Biochemistry: Structure and function of macromolecules (proteins, lipids, carbohydrates, nucleic acids), enzyme kinetics, and metabolic pathways.
Molecular Biology: DNA replication, transcription, translation, and gene regulation.
Cell Biology: Membrane structure, organelle functions, signal transduction, and cell division.
Genetics: Mendelian inheritance, gene expression, genetic disorders, and population genetics.
Physiology: Functions of major organ systems, homeostasis, and communication between cells and tissues.
Critical thinking and problem-solving skills are essential to succeed in this section. You’ll need to understand the interplay of biological molecules, cellular structures, and biochemical pathways in maintaining the function of living systems.
