|---|
| Aerobic | oxygen containing |
| Anarobic | Oxygen lacking |
| Cellular respiration | the aerobic harvesting of energy from food molecules by cells |
| Redox reaction | The movement of electrons from one molecule to another is an oxidation-reduction reaction |
| Oxidation | the loss of electrons to another substance |
| Reduction | the addition of elctrons to another substance |
| Dehydrogenase | a key enzyme for oxidation |
| NAD+ | nicotinamide adenine dinucleotide, is an organic molcule that cells make from a vitamin and use to shuttle electrons in redox reactions |
| Electron Carrier | delivering its electron load |
| Electrom transport chains | ordered groups of molecules are embedded in membranes in the eukaryotic cell's mitochondria |
| Chemiososis | cells use potential energy in concentrated gradients to make ATP |
| ATP Synthases | protein complexes that resid in membranes |
| Substrate-level phosphorylation | an enzyme transfers a phosphate group from an organic substrate molecule to ADP |
| Glycolysis | Occurs in the cytoplasm fluid of the cell, begins respiration by breaking down glucose into 2 molecules of a compoud called pyruvic acid |
| krebs Cycle | takes place ithin the mitochondria, completes the breakdown of glucose by decomposing a derivative of pyruvic acid to carbon dioxide |
| Intermediates | The compouds that form inbetween the initial reactant |
| Acetyl CoA | a high-energy fuel molecule for the krebs cycle |
| Alcoholic Fermentation | the production of ethanol from glucose |
| Lactic acid fermentation | lactic acid is produced when NADH from glyoclysis is oxidized |
| Strict Anaerobes | require anaerobic conditions and are poisoned by oxygen |
| Facultative anaerobe | can make ATp either by fermentation or by chemiosmosis depending on if O2 is avalible |
