BIOL 209 Quiz: Test 2
Document Summary
They need carbon and energy sources (in order to synthesize the components necessary for growth). Starting with one cell you end up with two cells = binary fission. They need energy and nutrients to make two genomes and more of everything. Just looking at it you can see that they need more membrane and ribosomes. They need polysaccharides, proteins, rna, dna, phospholipids, ions, and small molecules. They need physical things necessary to make more proteins, polysaccharides, etc. Different microbes use different sources of nutrients autotrophs (producers) can use. Co2 directly-photosynthesis, while heterotrophs (consumers) use nutrients derived from other organisms. A lot of our focus is on the heterotrophs. Instead of fixing co2 they get carbon from other sources. Active transport (low high; against the concentration gradient) They use energy for all of their independent processes. They use them for transport, creating new macromolecules; they use energy to physically move (find things).
