The process of fermentation involves the conversion of sugars into which of the following compounds?
Ethene
Ethanoic acid
Methane
Ethanol
Ethanol
Fermentation is a metabolic process that produces chemical changes in organic substrates through the action of enzymes. In the most common form, known as alcoholic fermentation, microorganisms like yeast convert sugars into ethanol and carbon dioxide.

Think of it like a biological engine running in a garage with the door closed (anaerobic conditions); instead of just exhaust gas, it produces 'bio-fuel' (ethanol) as a byproduct.
Yeast makes the 'Ethan' (Ethanol) to reach the 'Plan' ( fermentation plan).
C6тАЛH12тАЛO6тАЛтЖТ2C2тАЛH5тАЛOH+2CO2тАЛ тАФ The general chemical equation for alcoholic fermentation.
The process is an anaerobic respiration pathway where glucose (C6тАЛH12тАЛO6тАЛ) is broken down into ethanol (C2тАЛH5тАЛOH) and carbon dioxide (CO2тАЛ). This happens when yeast enzymes catalyze the conversion of pyruvate into these end-products in the absence of oxygen.
Fermentation is an anaerobic process occurring in the absence of oxygen.
It is industrially important for the production of beverages, bread, and biofuels.
The process relies on specific enzymes produced by microorganisms like Saccharomyces cerevisiae (brewer's yeast).
Preservation of food
Production of fuels like bio-ethanol
Enhancement of nutritional profiles in some foods
Can produce unwanted byproducts
Limited energy yield compared to aerobic respiration
Brewing industry (beer/wine production)
Baking industry (dough rising via CO2)
Ethene is an alkene used in the plastic industry.
Ethanoic acid is the main component of vinegar, often produced via the oxidation of ethanol.
Methane is a simple alkane and the primary component of natural gas.
D is correct тАФ Fermentation by yeast primarily converts simple sugars into ethanol and carbon dioxide.
Remember that while fermentation is often associated with alcohol, different types of fermentation (like lactic acid fermentation in muscles) produce different end-products; always check the context.
