Question

1. the active ingredient in the conversion of organic material into alcohol is ____.

Yeast is a microorganism that carries out fermentation, the metabolic process that converts organic materials (like sugars from organic matter) into alcohol. Garbage is organic material to be converted, sugarcane is a source of sugar for fermentation, and methane is a byproduct of anaerobic digestion of organic matter, not the active agent for alcohol conversion.
