- Refer to the figure. To identify the molecule that accepts CO2, Calvin and Benson manipulated the carbon fixation cycle by either cutting off CO2 or cutting off light from cultures of photosynthetic algae. They then measured the concentrations of various metabolites immediately following the manipulation. How would these experiments help identify the CO2 acceptor? a) The CO2 acceptor concentration would decrease when either the CO2 or light is cut off. b)The CO2 acceptor concentration would decrease when the CO2 is cut off but increase when the light is cut off. c)The CO2 acceptor concentration would stay the same regardless of the CO2 or light. d)The CO2 acceptor concentration would increase when either the CO2 or light is cut off. e)The CO2 acceptor concentration would increase when the CO2 is cut off but decrease when the light is cut off.arrow_forwardWhat are the selective attributes and criteria used for the selection of algae strains with reference to algal biofuels?

- Explain two ways in which archaea metabolize inorganiccompounds in extreme environments.arrow_forwardThe 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). What does the dashed line signify?arrow_forwardWhy is energy required for nutrient transport?
