The main difference between lactic acid fermentation and alcoholic fermentation is that lactic acid fermentation a. produces more energy than alcoholic fermentation. b. produces less energy than alcoholic fermentation. c. regenerates nad⁺ but alcoholic fermentation does not. d. regenerates a two-carbon molecule, but alcoholic fermentation does not. e. regenerates a three-carbon molecule and alcoholic fermentation does not.

e. regenerates a three-carbon molecule and alcoholic fermentation does not.

Explanation:

Lactic acid fermentation includes the reduction of pyruvate into lactate. Lactate is a three-carbon molecule. Reduction of pyruvate into lactate also regenerate NAD+ required to continue the process of glycolysis.

Alcoholic fermentation includes decarboxylation of pyruvate into acetaldehyde followed by its reduction of alcohol. The alcohol formed as end product is a two-carbon molecule (ethanol). Here, NADH serves as electron donor and is oxidized into NAD+. Therefore, both the process regenerate NAD+ but ethanol fermentation does not regenerate the three-carbon molecule since one carbon is lost as CO2.

a fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing energy originating in ancient photosynthesis.[1] the age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years.[2] fossil fuels contain high percentages of carbon and include petroleum, coal, and natural gas.[3] other commonly used derivatives include kerosene and propane. fossil fuels range from volatile materials with low carbon to hydrogen ratios like methane, to liquids like petroleum, to nonvolatile materials composed of almost pure carbon, like anthracite coal. methane can be found in hydrocarbon fields either alone, associated with oil, or in the form of methane clathrates.

the theory that fossil fuels formed from the fossilized remains of dead plants by exposure to heat and pressure in the earth's crust over millions of years was first introduced by andreas libavius "in his 1597 alchemia [alchymia]" and later by mikhail lomonosov "as early as 1757 and certainly by 1763".[4] the first use of the term "fossil fuel" was by the german chemist caspar neumann, in english translation in 1759.[5]

in 2017 the world's primary energy sources consisted of petroleum (34%), coal (28%), natural gas (23%), amounting to an 85% share for fossil fuels in primary energy consumption in the world.[6] non-fossil sources in 2006 included nuclear (8.5%), hydroelectric (6.3%), and others (geothermal, solar, tidal, wind, wood, waste) amounting to 0.9%.[7] world energy consumption was growing at about 2.3% per year. in 2015 about 18% of worldwide consumption was from renewable sources.[8]
