If a toxin blocked the first compound of the Electron Transport Chain what would be the effect on an organism?
Some friends are trying to make wine in their basement. They've added yeast (which is a facultative anaerobe - it can perform both aerobic respiration and fermentation) to a sweet grape juice mixture and have allowed the yeast to grow. After several days they find that sugar levels in the grape juice have dropped, but there's no alcohol in the mixture. The most likely explanation is that
the mixture needs less oxygen, because yeast only produce alcohol in the absence of oxygen
the mixture needs less sugar, because high sugar concentrations prevent fermentation
the mixture needs more sugar, because yeast need a lot of energy before they can begin to produce alcohol
the yeast used the alcohol as a carbon source
the mixture needs more oxygen, because yeast need oxygen to break down sugar and get enough energy to produce alcohol

- The genus Ferroplasma consists of a few species of acid-loving archaea. One species, F. acidarmanus, was discovered to be the main component of slime streamers (a type of biofilm) deep inside an abandoned California copper mine (Figure 4.11A). F. acidarmanus cells use an ancient energy-harvesting pathway that combines oxygen with ironsulfur compounds in minerals such as pyrite. This reaction dissolves the minerals, so groundwater that seeps into the mine ends up with extremely high concentrations of metal ions such as copper, zinc, cadmium, and arsenic. The reaction also produces sulfuric acid, which lowers the pH of the water around the cells to zero. Despite living in an environment with a composition similar to hot battery acid, F. acidarmanus cells maintain their internal pH at a cozy 5.0. Thus, researchers investigating Ferroplasma metabolic enzymes were surprised to discover that most of the cells enzymes function best at very low pH (Figure 4.11B). A. Deep inside one of the most toxic sites in the United States: Iron Mountain Mine, in California. The water in this stream, which is about 1 meter (3 feet) wide in this photo, is hot (around 40C, or 104F), heavily laden with arsenic and other toxic metals, and has a pH of zero. Slime streamers growing in it are a biofilm dominated by a species of archaea, Ferroplasma acidarmanus. B. pH profiles of four enzymes isolated from F. acidarmus. Researchers had expected these enzymes to function best at the cells cytoplasmic pH (5.0).

- You are observing an organism. It appears to extract energy stored in inorganic molecules like ammonia, nitrites and hydrogen sulfide; it uses carbon dioxide as its primary carbon source. What kind of organism is it? (Hint: think nutrition groups)arrow_forwardYou are talking with a winemaker about yeast. "I know that yeast can survive under both aerobic and anaerobic conditions," he says, "but what I don't understand is why they seem to need so much more sugar under anaerobic conditions. I think they gobble a hundred times as much sugar." Can you explain to him why yeast might need more sugar under anaerobic conditions than under aerobic conditions? Is his estimation of a hundred times as much sugar reasonable?arrow_forwardIn a redox reaction, an atom or molecule loses excited electrons to become___and have__energy.
