Textbook Question
Chapter 15, Problem 13P
If algae are exposed to 14C02 for a brief period while illuminated, the labeled carbon is initially found almost entirely in the carboxyl group of 3- phosphoglycerate. However, if illumination is continued after the label pulse, other carbon atoms become labeled. Explain.

Some halophiles often have an extremely high amino acid concentration in the cell and grow at pH of 7.1 with the intracellular pH being similar. Why might the high amino acid concentration allow these cells to live in high-salt environments?

This group of bacteria are capable of photosynthesizing. Do they contain chloroplasts? Explain.arrow_forwardIn a classic experiment in photosynthesis performed in 1883 by the German botanist Thomas Engelmann, he surrounded a filament of algae with oxygen-requiring bacteria. He then exposed the algal strand to the visible-light spectrum along its length. In which wavelengths of light along the algal strand would you expect the bacteria to cluster. Explain.arrow_forward

Explain.arrow_forwardCan xylane powder from beechwood be dissolved in M9 media? I'm evaluating the production of hydrogen with E. coli (it has a construction that alows this strain to depolimerize xylane into xylose monomers by an endoxylanase), but i have a limited amount of this xylane, and i read TB, AM1 & M9 mediums were used, but they don't say if they just poured the xylan powder into the media solution, i also read they autoclaved it with a soft acid solution and then neutralized it with a basic soluction, but this is an acid hydrolyzate (AH) plus enzymatic hydrolysis (EH). It ´s certain that using both would enhance available xylose concentration, but i want to evaluate EH by itself, and i still can't find if it is just added as powder to the media. Would it dissolve? do i have to add some kind of buffer to the media?.arrow_forward
