Photosynthesis 1
... Cycle). When the two atoms of hydrogen join with NADP, oxygen is liberated, and this is the source of oxygen gas in our atmosphere. ATP and NADPH2from the light reactions are ... some intestinal gas, particularly the combustible component of flatulence. They produce methane gas anaerobically (without oxygen) by removing the electrons from hydrogen gas. The electrons and H+ ions from hydrogen gas are ...

... a reaction chamber in the abdomen. Catalase breaks down the hydrogen peroxide into water and oxygen gas. Peroxidase oxidizes hydroquinone into benzoquinone. The mixture of chemicals and enzymes volatilizes instantly upon ... energy reserve for a flight of a few hours before he literally runs out of "gas." Male black rain beetle (Pleocoma puncticollis), a large scarab beetle that appears with the ...

California's Pink Salt Lakes
... the kingdom Euryarchaeota within the Archaea domain. Halophiles need oxygen while methanogens are anaerobic; however, halophiles can produce energy without oxygen in two ways: from the degradation of arginine, and ... remnants from the halophile's anaerobic ancestry when the earth's atmosphere lacked free oxygen gas more than 2 billion years ago. One perplexing question about the evolution of life ...

Vegetative Terminology (Part 1)
... view of prop roots showing numerous pores called lenticels which provide gas exchange and an additional source of oxygen for the submersed roots. Mangroves survive in seawater with a salinity ... are called pneumatophores. The porous pneumatophores enable the water-logged roots to carry on gas exchange with the atmosphere. Unlike positively geotrophic roots, the pneumatphores (called "aerial roots") ...

Leaf Terminology (Part 2)
... they remain turgid. If the guard cells become wilted or flaccid, the stoma closes, and gas exchange cannot occur. Insulation also shields plants from intense solar radiation and severe cold and ... Oaks In San Diego County Plants carry on gas exchange through minute pores called stomata. Carbon dioxide from the atmosphere enters the stomata and oxygen produced by photosynthesis diffuses out of the ...

Azolla and Anaebaena Symbiosis
... Mars Article Nitrogen fixation is a remarkable prokaryotic skill in which inert atmospheric nitrogen gas (N2) is combined with hydrogen to form ammonia (NH3). This vital process along ... regular photosynthetic cells of Anabaena, and they become non-photosynthetic (and do not produce oxygen). This fact is especially noteworthy because nitrogen fixation requires the essential enzyme nitrogenase, and ...
