25 Metabolism
Chpt 25
| Question | Answer |
|---|---|
| metabolism | all chemical reactions |
| catabolism | chemical reaction that breaks down complex organic molecules, produces more energy than it uses |
| anabolism | chemical reaction that breaks down ssimple molecules and monomers |
| oxidation | removal of electronsfrom an atom or molecule and decreases potential energy |
| reduction | opposite of oxidation, additon of electrons to a molecule, increase potential energy |
| coenzymes | transport vechicle when a substance is oxidized, carrys free cell to another compound, carry H atoms NAD & FAD |
| phosphorylation | addition of phosphate group added to a molecule |
| cell respiration | oxidation of glucose to produce ATP, invloves glycosis, formation of acetyl coenzyme A, the krebs cycle and elctron transport chain |
| glycosis | set of reactions in which 1 glucose molecule is oxidized |
| oxidation of glucose | involves glycosis, the formation of acetyl coenzyme A, the Krebs cycle and electron transport chart |
| anaerobic cellular respiration | production of ATP without O2 |
| reduction | opposite of oxidation, additon of electrons to a molecule, increase potential energy |
| coenzymes | transport vechicle when a substance is oxidized, carrys free cell to another compound, carry H atoms NAD & FAD |
| phosphorylation | addition of phosphate group added to a molecule |
| cell respiration | oxidation of glucose to produce ATP, invloves glycosis, formation of acetyl coenzyme A, the krebs cycle and elctron transport chain |
| glycosis | set of reactions in which 1 glucose molecule is oxidized |
| oxidation of glucose | involves glycosis, the formation of acetyl coenzyme A, the Krebs cycle and electron transport chart |
| anaerobic cellular respiration | production of ATP without O2 |
| processes that are called anaerobic respiration | glycolysis, formation of acetyl coenzyme A, krebs, electron transport chain |
| reactions of Krebs cycle occur where | matrix of mitochondria |
| Co2 is released during which cycle | krebs cycle |
| 3 results of Krebs Cycle | production of reduced coenzymes NADH+H and FADH2 which contained stored energy, generations of GTP, formation of CO2 that is transported to lungs for exhalation |
| GTP | high energy compound |
| Fate of pyruvic acid | when o2 is plentiful pyruvic acid enters mitochondria and is converted to acetyl coenzyme A and enters the the krebs cycle, when o2 is scarce most pyruvic acid is converted to lactic acid via an anerobic pathway |
