Corn is grown for human consumption, feeding livestock, and producing ethanol for fuel. The starches in corn are broken down by enzymes into dextrose, $\mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6},$ and a yeast fermentation process produces carbon dioxide and ethanol, $\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{OH},$ from the dextrose. Write the balanced chemical equation for the production of ethanol.

Key Concepts

Stoichiometry

Stoichiometry is the quantitative relationship between reactants and products in a chemical reaction. It enables precise calculations to determine the amounts of substances involved, ensuring that reactions are balanced according to the conservation of mass.

Biofuel Production

Biofuel production refers to the conversion of biological materials into fuels, such as converting agricultural products into ethanol. This field applies both chemical and biological processes to produce renewable energy sources, contributing to sustainable energy solutions.

Balanced Chemical Equations

Balanced chemical equations represent chemical reactions with equal numbers of atoms for each element on both sides, adhering to the law of conservation of mass. This concept is crucial for accurately depicting the stoichiometry of reactions and predicting the products formed.

Fermentation

Fermentation is a metabolic process in which microorganisms such as yeast convert sugars into alcohol and carbon dioxide in the absence of oxygen. This process is fundamental in various industrial applications, particularly in the production of biofuels like ethanol.

Enzyme Catalysis

Enzyme catalysis involves biological molecules called enzymes that accelerate chemical reactions by lowering the activation energy required. In biochemical contexts, enzymes are essential for breaking down complex carbohydrates into simpler sugars, which can then be fermented.
