Term
glycolysis
Definition
1. An ATP-generating metabolic process that occurs in nearly all living cells in which glucose is converted in a series of steps to pyruvic acid. 2. The metabolic breakdown of glucose and other sugars that releases energy in the form of ATP. 3.The biochemical pathway that breaks down a molecule of glucose into two molecules of pyruvate plus energy
Term
lactic acid
Definition
A syrupy, water-soluble liquid, C3H6O3, produced in muscles as a result of anaerobic glucose metabolism, and present in sour milk, molasses, various fruits, and wines. A synthetic form of the compound is used in foods and beverages as a flavoring and preservative, in dyeing and textile printing, and in pharmaceuticals.
Term
ethanol
Definition
An alcohol obtained from the fermentation of sugars and starches or by chemical synthesis. It is the intoxicating ingredient of alcoholic beverages, and is also used as a solvent, in explosives, and as an additive to or replacement for petroleum-based fuels. Also called ethyl alcohol, grain alcohol. Chemical formula: C2H6O.
Term
CO2
Definition
1. a heavy odorless colorless gas formed during respiration and by the decomposition of organic substances; absorbed from the air by plants in photosynthesis
Term
BROMTHYMOL BLUE
Definition
A dye used as an acid-base indicator
Term
ph indicator
Definition
an indicator that changes color on going from acidic to basic solutions
Term
AMMONIUM HYDROXIDE (base)
Definition
a water solution of ammonia(a basic compound, NH4OH, existing only in solution, formed by dissolving ammonia gas in water.)
Term
calcium carbonate
Definition
A colorless or white crystalline compound, CaCO3, occurring naturally as chalk, limestone, marble, and other forms and used in a wide variety of manufactured products including commercial chalk, medicines, and dentifrices.
