Document Summary
Describe the adaptations found in photographs that enable them to be successful photosynthetic microbes. Compare and contrast the function of sulfur granules. Differentiate between pili, capsules, slime layers and flagella. Explain the function of most proteins, the pmf and flagella in the tumble-run cycle of cell movement. Thylakoids: a membrane bound compartment inside the chloroplast of cyanobacteria; site of light dependent reactions of photosynthesis. Carboxysomes: intracellular structures found in autotrophic bacteria; contain enzymes that allow for carbon fixation within the organism. Gas vesicles: allows for microorganisms to float in water; made up of proteins. Storage granules: glycogen, phb and pha are stored as reserves for energy / sulfur. Magnetosomes: membranous prokaryotic structures that function in aiding the bacteria in orientation within geomagnetic fields. Pili or fimbriae are straight filaments of protein monomers called pilin. Sex pili are used for bacterial conjugation or mating. Polysaccharide layers that surround the bacterial cells.
