Term
Glycolysis
Definition
the enzymatic breakdown of a carbohydrate (as glucose or glycogen) by way of phosphate derivatives with the production of pyruvic or lactic acid and energy stored in high-energy phosphate bonds of ATP—called also Embden-Meyerhof pathway
Term
Anaerobic
Definition
living, active, or occurring in the absence of free oxygen <during heavy exercise anaerobic respiration occurs, pyruvic acid acts as a hydrogen acceptor, and lactic acid builds up in the tissues>
Term
NADH
Definition
the reduced form of NAD
Term
Cellular Respiration
Definition
any of various energy-yielding oxidative reactions in living matter that typically involve transfer of oxygen and production of carbon dioxide and water as end products
Term
Pyruvic acid
Definition
a 3-carbon acid C3H4O3 that is an intermediate in carbohydrate metabolism and can be formed either from glucose after phosphorylation or from glycogen by glycolysis
Term
Electron carrier
Definition
Term
ATP
Definition
a phosphorylated nucleotide C10H16N5O13P3 composed of adenosine and three phosphate groups that supplies energy for many biochemical cellular processes by undergoing enzymatic hydrolysis especially to ADP—called also adenosine triphosphate
Term
Krebs cycle
Definition
a sequence of reactions in the living organism in which oxidation of acetic acid or acetyl equivalent provides energy for storage in phosphate bonds (as in ATP)—called also citric acid cycle, tricarboxylic acid cycle
Term
FADH2
Definition
Term
Aerobic
Definition
of, relating to, or being activity which increases the body's demand for oxygen thereby resulting in a marked temporary increase in respiration and heart rate
Term
Electron transport chain
Definition
Term
Carrier protein
Definition
Term
Fermentation
Definition
an enzymatically controlled anaerobic breakdown of an energy-rich compound (as a carbohydrate to carbon dioxide and alcohol or to an organic acid); an enzymatically controlled transformation of an organic compound
