Document Summary
Living things need stable internal environments (temp. , ph, ext. ) So we take in macromolecules (proteins, lipids, carbohydrates) which are broken down. It takes energy input to break things down, but net product is positive because it. Requires energy input, and a source of electrons. Products have higher energy state and are more reduced than the reactants. Pathways overlap and share metabolites or substrates, so regulation decides what pathway gets the reactants. We know what we know because we studied simpler. Different needs - specific needs that point to organisms needs in their specific niche. Was not a good classification, could be deceptive. 3. 6. 4. (carl woese), found major differences between prokaryotes. Some dna on certain prokaryotes was similar to eukaryotes while some was very different. Bacteria and archaea have differences between translation and transcription that. Archaea and eukarya match exchange and how they relate to drawing phylogenetic trees. Can happen between completely different species, it makes phylogenetic trees much more complicated.
