  • Effect of Temperature on Respiration of Yeast
    Living organisms catabolize organic molecules within their cells and use the energy released to manufacture ATP by phosphorylating ADP. Many prokaryotes and virtually all Eukaryotes phosphorylate ADP either through fermentation (anaerobic) or respiration (aerobic). Both of these processes involve ox...
