Document Summary
Inner membrane is not compoluted like the mitochondria (chyste). Circular chromosomes: 70s ribosomes, two membranes, outer membrane has porins. Every single eukaryote cell will all have a mitochondria (except some protists) Chloroplasts harvest light energy to convert to chemical energy. Histones clip or organize the dna so it can be super coiled and can be stored within the small space. Porins transport proteins hydrophilic within gram neg. bacteria in outer membrane. Most closely related to cyanobacteria: blue-green algae. Elements required in large amounts to build macromolecules. C, h, o, n, p and s makeup > 90% of the dry weight of the cell. Protein c, h, o, n (and s) Polymer of made of building blocks amino acids. Building blocks = fatty acids and glycerol ex. Nucleic acids c, h, o, n, p. Ions, sodium, calcium = make up the other 10% 2 of the twenty proteins have sulfur as part the r g(cid:396)oup of the se(cid:395)uence.
