Final answer:
None of the given options accurately represent the percentage of anaerobic respiration that occurs through glycolysis alone, as glycolysis is only the first stage of the complex anaerobic respiration process.
Step-by-step explanation:
Regarding anaerobic respiration, glycolysis is a critical process that happens whether oxygen is present or not. A common misconception is that glycolysis accounts for a large percentage of the anaerobic respiration process; however, in reality, glycolysis is just the first stage of cellular respiration. Fermentation or anaerobic respiration follows glycolysis when no oxygen is available and includes additional steps depending on the type of anaerobic process occurring, be it lactic acid fermentation or alcohol fermentation. Overall, the entire process of anaerobic respiration is not solely comprised of glycolysis; therefore, none of the given percentage options accurately represent the percentage of anaerobic respiration occurring through glycolysis alone, as glycolysis is simply one component of the process.
