A close-up photograph displays a section of a white paper document, likely a textbook page, populated with black printed text and chemical diagrams in Bulgarian. The document details organic chemistry concepts and reactions. The top portion describes the "interaction with freshly precipitated Cu(OH)2," illustrating the formation of a dark, clear copper glucoside solution and a dark complex compound from C6H10O4. A prominent heading, "Реакции до цялата молекула" (Reactions of the whole molecule), introduces subsequent subsections. These subsections delineate specific biochemical processes: * "Алкохолна ферментация" (Alcoholic fermentation): C6H12O6 (glucose) converts to 2C2H5OH (ethanol) and 2CO2, catalyzed by zymase. * "Оцетнокисела ферментация (аеробно след алкохол ферментация)" (Acetic acid fermentation, aerobic after alcoholic fermentation): 2C2H5OH reacts with 4O2 to yield CH3COOH (acetic acid), 2CO2, and 4H2O. * "Млечнокисела ферментация" (Lactic acid fermentation): C6H12O6 (glucose) transforms into 2-hydroxypropanoic acid (lactic acid), facilitated by enzymes. * "Горене (пълно окисление)" (Combustion, complete oxidation): C6H12O6 (glucose/fructose) reacts with 6O2 to produce 6CO2 and 6H2O. A concluding paragraph discusses photosynthesis as the reverse reaction of combustion in green plants, leading to carbohydrate accumulation and oxygen release.
