This course will be comprised of approximately 15-20 units. Students will study: 1) the basic biochemical molecules, their structure and functions. These will include: proteins, enzymes, lipids, carbohydrates (including glycogen metabolism and gluconeogenesis) and nucleic acids (including replication, transcription and protein synthesis). 2) Studies on intermediary metabolism will include: glycolysis, the pentose phosphate pathway, the citric acid cycle (Krebs or TCA cycle), oxidative phosphorylation, lipid metabolism, amino acid metabolism. 3) Students will also study signal transduction pathways and mechanisms involved in the action of hormones and neurotransmitters.
