Document Summary
Ftsz many bacteria (& archaea) forms ring during cytokinesis. Mreb/mbl many rods maintains shape by positioning peptidoglycan synthesis machinery. Interior membranes derived from plasma membranes or continuous with it. Inclusions (or microcompartments) granules of organic or inorganic material that are stockpiled storage of nutrients, metabolic end products, energy, building blocks glycogen storage carbon storage poly- -hydroxybutyrate (phb) phosphate storage. Polyphosphate amino acids storage cyanophycin granules some enclosed by a single-layer shell that varies in composition made of proteins or lipids functional compartments holds, surrounds, and contains certain metabolic processes polyhedral shape, contains enzymes. Rubisco & co2, accumulated in a polyhedral protein shell . Gets proper light, nutrients, and co2 by making or collapsing vesicles. Very electron dense, hooked together by cytoskeleton proteins. Cross links from 3rd aa to 4th aa, lose 5th aa (release energy) 100 % peptidoglycan: more stable contains teichoic acid within glycan structure, negatively charged. Oligo-side chain core polysachharide lipid a (glucosoamine-p + fatty acid tails)
