Most organisms will use some form of fermentation to accomplish the regeneration of NAD+, ensuring the continuation of glycolysis. The regeneration of NAD+ in fermentation is not accompanied by ATP production; therefore, the potential for NADH to produce ATP using an electron transport chain is not utilized.

(The “proof” of an alcoholic beverage is just twice the percentage of ethanol.) Alcohol’s intoxicating effects are well known, and it is a mild depressant. Ketones are difficult to oxidize further, because there is no way to add another oxygen atom to the carbon atom in the >C=O group, nor is there a way to remove hydrogen atoms from the C and O atoms in the >C=O group.

It traces the historical development of enzyme study from the 19th century through the understanding of their structures in the 1920s. It explains Michaelis-Menten kinetics, which describes enzyme-substrate interactions, and introduces key parameters like the Michaelis constant (K_M) that influence reaction rates.

In practice, the name alcohol is restricted to compounds that have their –OH group bonded to a saturated, sp³-hybridized carbon atom, while compounds with their –OH group bonded to a vinylic, sp²-hybridized carbon are called enols.

NAD+ is a required molecule necessary for the oxidation of Glyceraldehyde-3-phosphate to produce the high energy molecule 1,3-bisphosphoglycerate. Fermentation occurs in the cytosol of cells.
