Ch.8 Notes Date Notes Questions 10/12/15 To types of metabolic pathways Catabolic pathways (breaking down, breaking down energy) Anabolic pathways (storing energy, build up) Pathways can be complex and have multiple steps Pathways are the chemical reactions Ex pathways a->b->c-> (a, b and c are chemicals) Living organisms are chemical computers Design like circuit boards Some people working on DNA based computer Also there are works on neuro networks Organisms always share chemicals with everyone Prokaryotes have a much simpler pathways than eukaryotes Metabolic theory that there is a mathematical formula that can explain the interaction of organisms. Energy cannot be created or destroyed Sunlight->Glucose->ATP->Heat Glucose more desired because easiest way to get ATP
