What are the three end products of fermentation?
Fermentation reacts NADH with an endogenous, organic electron acceptor. Usually this is pyruvate formed from sugar through glycolysis. The reaction produces NAD+ and an organic product, typical examples being ethanol, lactic acid, and hydrogen gas (H2), and often also carbon dioxide.
What is a common by product from fermentation?
The main fermentation products include organic acids, ethyl alcohol and carbon dioxide. Commercially the mostly important are lactic acid and ethanolic fermentations.

Butyric acid | Butyric acid, CO2, hydrogen gas | Clostridium butyricum |
What are the starting and ending products of fermentation?
Fermentation Review Fermentation happens in anaerobic conditions (i.e.,without oxygen). Fermentation begins with glycolysis which breaks down glucose into two pyruvate molecules and produces two ATP (net) and two NADH. Alcoholic fermentation occurs in yeast and produces ethanol and carbon dioxide.
Is a common end product of fermentation?
Products of Fermentation While there are a number of products from fermentation, the most common are ethanol, lactic acid, carbon dioxide, and hydrogen gas (H2). These products are used commercially in foods, vitamins, pharmaceuticals, or as industrial chemicals.
Is ethanol a product of fermentation?
Abstract. Alcoholic fermentation is a complex biochemical process during which yeasts convert sugars to ethanol, carbon dioxide, and other metabolic byproducts that contribute to the chemical composition and sensorial properties of the fermented foodstuffs.
Which are the end products of aerobic respiration?
Carbon dioxide, water and energy.
