Chapter 8 Reading Cell Reproduction: Mitosis and Meiosis 8.1, 8.2, 8.4, 8.5, 8.6, 8.9, 8.11, 8.12, 8.13, 8.14, 8.15, 8.17, 8.19, 8.20, 8.21 10.4 Important Concepts Mitotic cell divisions and cell number Chromosomes and karyotypes Aneuploid Syndromes Mitotic cell cycle DNA replication M-phase (prophase, metaphase, anaphase, telophase)
Cellular Respiration Glycolysis “Splitting of glucose” into two 3-carbon molecules Some ATP synthesis Some NADH synthesis (takes up electrons) TCA Cycle (Citric acid cycle, Krebs Cycle) CO2 production Some ATP synthesis Some NADH synthesis (takes up electrons) Electron Transport (Oxidative Phosphorylation) NADH gives up electrons O2 converted to H2O Lots of ATP synthesis!!!!!
