Alcoholic beverages like wine and beer
Explanation
The metabolic process described is alcoholic fermentation. This is an anaerobic form of respiration carried out by yeast (specifically Saccharomyces cerevisiae), wherein simple sugars (glucose) are incompletely oxidized to produce ethanol and carbon dioxide.Option Analysis:
- Pharmaceutical antibiotics is incorrect: Pharmaceutical antibiotics are secondary metabolites produced by microbes (bacteria and fungi) to inhibit the growth of pathogens. While fermentation technology is used to culture these microbes, the specific metabolic pathway of converting sugar to alcohol is not the mechanism for antibiotic synthesis.
- Alcoholic beverages like wine and beer is correct: The fermentation of malted cereals and fruit juices by yeast is the foundational process for producing alcoholic beverages. Depending on the raw material and processing (distillation vs. non-distillation), this yields products such as wine, beer, whisky, brandy, and rum.
- Industrial oxygen is incorrect: Industrial oxygen is primarily produced through the fractional distillation of liquid air, which is a physical separation process rather than a microbial metabolic process.
- Synthetic nitrogen fertilizers is incorrect: Synthetic nitrogen fertilizers are manufactured using chemical processes, most notably the Haber-Bosch process, which synthesizes ammonia from atmospheric nitrogen and hydrogen under high pressure and temperature.
Key Takeaway: Saccharomyces cerevisiae, commonly known as Brewer’s Yeast, is utilized in the industrial production of alcoholic beverages through anaerobic fermentation, converting carbohydrates into ethanol and CO2.
