Biochemistry of the hydrogenosome. Pyruvate is taken up by hydrogenosome and oxidized to H2+CO2,acetate and ATP.The key enzymes are pyruvate:ferredoxin oxidareductase and hydrogenase.Endosymbiotic methanogens are often present in the cytoplasm of hydrogenosome-containing eukaryotes, producing methane from the H2 +CO2

Chloroplast Chloroplast Thylakoid Structure pue Figure 14-6 Brock Biology of Microorganisms 11/e 2006 Pearson Prentice Hall,Inc. Chloroplasts have a permeable outermost membrane, a much less permeable inner membrane,and an intermembrane space. Chlorophyll and all other components needed for photosynthesis are located in a series of flattened membrane discs called thylakoids.类囊体 The inner membrane is not folded into cristae like that of mitochondrion.
