Term
cellular respiration
Definition
the process by which the energy is stored in food inside the cells is released
Term
ATP (adenosine triphosphate)
Definition
the compound in which energy released by cellular respiration is stored
Term
ADP (adenosine diphosphate)
Definition
the remaining molecule from the third phosphate being removed from ATP
Term
oxidation
Definition
any chemical change in which an atom or a molecule loses a molecule
Term
reduction
Definition
chemical reaction in which substance gains an electron
Term
oxidation-reduction reaction
Definition
a reaction in which one substance is oxidized and another substance is reduced
Term
aerobic resperation
Definition
respiration requiring the presence of free oxygen, in which Glucose is completely oxidized to carbon dioxide and water
Term
anaerobic respiration
Definition
respiration in the absence of free oxygen, in which glucose is partially oxidized
Term
glcolysis
Definition
the process of breaking down the glucose molecule into two three-carbon pyruvic acid molecules
Term
fermentation
Definition
following glycolysis, the conversion of pyruvic acid to an end product with no further release of energy
Term
acetyl CoA
Definition
a compound produced during pyruvic acid breakdown by the combination of an acetyl group group with coenzymes
Term
Krebs Cycle
Definition
the series of chemical reactions that begins with the acetyl coenzymes A (CoA) formed from pyruvic acid
Term
electron transport chain
Definition
a series of oxidation-reduction reactions in which most of the energy produced from the breakdown of glucose is transferred to ATP
Term
oxygen debt
Definition
the amount of oxygen needed to get rid of lactic acid
