Document Summary
A pattern in biological organization: idea of hierarchy, must understand the interaction of all levels, what does it mean to be living, all living things share basic characteristics. Figure 22. 4: lipids, nucleic acids, carbohydrates, proteins, prokaryotic (bacteria) cells: simple, single, primitive cell w/o nucleus, eukaryotic cells: complex, multiple w/ a nucleus, karyote: means nucleus (centre/middle, pro: before, eu: true. Evolution of life : prokaryotes fermentation = 2 atp/glucose cellular respiration = 36 atp/glucose, atmospheric oxygen produced, single celled eukaryotes , multicellular eukaryotes , animals. 6: paleozoic era, mesozoic era, cenozoic era, humans have barely been on earth land plants. Slide 21: prokaryotes/bacteria, eubacteria (don"t talk about, archebacteria (don"t discuss, eukaryotes. Characteristics of all life: made up of organic molecules, organic molecules have carbon and hydrogen covalent bonfs, 4 types of biological macromolecules, carbohydrates** + product: + (enzymes each different, need each enzyme to keep the process going, if you"re missing one. 4 biological macromolecules *: carbohydrates, lipids, proteins, nucleic acid.
