Bio AP: Cellular Respiration
| Question | Answer |
|---|---|
| Fermentation | Partial degradation of sugars that occurs without oxygen |
| Aerobic Respiration | a catabolic pathway that consumes oxygen and organic molecules, producing ATP. Most efficient. Carried out in most eukaryotic cells & prokaryotic organisms. |
| Cellular Respiration | the catabolic pathways of aerobic and anaerobic respiration, which break down organic molecules for the production of ATP |
| Redox Reactions (Oxidation-Reduction Reaction) | a chemical reaction involving teh complete or partial transfer of one or more electrons from one reactant to another; |
| Oxidation | loss of electrons from one substance |
| Reduction | addition of electrons to another substance |
| Reducing Agent | electron donor |
| Oxidizing agent | electron acceptor |
| Electron Transport Chain | a sequence of electron carrier molecules that shuttle electrons during the redox reactions that release energy used to make ATP |
| Oxidative Phosphorylation | the production of ATP using energy derived from the redox reactions of an electron transport chain; 3rd major stage of cellular respiration |
| Glycolysis | Breaks down glucose into pyruvate |
| Citric Acid Cycle | chemical cycle involving 8 steps that completes the metabolic breakdown of glucose molecules begun in glycolysis by oxidizing pyruvate to carbon dioxide |
| Substrate-Level Phosphorylation | mode of ATP synthesis that occurs when an enzyme transfers a phosphate group from a substrate molecule to ADP as in oxidative phosphorylation. |
| Acetyl CoA | acetyl coenzyme A |
| Cytochromes | an iron-containing protein that is a component of electron transport chains in the mitochondria and chloroplasts of eukaryotic cells and the plasma membranes of prokaryotic cells |
| ATP Synthase |
