| Question | Answer |
|---|---|
| those that break down organic molecules for energy | catabolic pathways |
| those that build up organic molecules to store energy for later use. | anabolic pathways |
| a chemical pathway in which organic molecules are broken down to release energy in a quickly usable form | cellular respiration |
| uses molecular oxygen (O2) as the final electron acceptor in the reaction pathway | Aerobic respiration |
| Anaerobic pathways do not use oxygen as they perform respiration; these include | anaerobic respiration and fermentation |
| C6H12O6 + 6O2 + 6H2O → 6CO2 + 12H2O + energy (ATP) | Aerobic Respiration |
| 6CO2 + 12H2O + energy (light) → C6H12O6 + 6O2 + 6H2O | Photosynthesis |
| the first stage of aerobic respiration | Glycolysis |
| involves the conversion of each pyruvate into acetyl-CoA, releasing one CO2 for each pyruvate reactant. | The formation of acetyl CoA |
| oxidizes the remaining carbon atoms of each acetyl-CoA to CO2. | The citric acid cycle |
| In the final stage, oxidative phosphorylation, NADH and FADH2 deliver their energy-rich electrons into the | electron transport chain |
| a pathway present in some prokaryotes, is remarkably similar to aerobic respiration | Anaerobic respiration |
| the reactions of glycolysis still occur, making 2 ATPs by substrate-level phosphorylation | fermentation |
| light energy is converted into an organic molecule form such as glucose | photosynthesis |
| occur within the thylakoid membrane of chloroplasts | light-dependent reactions |
| use the energy in ATP and NADPH to synthesize glucose | carbon or Calvin cycle |
| incorporates CO2 into ribulose bisphosphate | ribisco |
| sometimes reduces the efficiency of photosynthesis | photorespiration |
| The rubisco enzyme will combine ___ | with RuBP when CO2 levels become particularly low |
| Cellular respiration can be divided into two basic categories | aerobic and anaerobic |
| is a series of membrane complexes that transfers energy-rich electrons from one complex to another in a chain | electron transport chain |
| The energy from the ______ is used to pump protons across the inner mitochondrial membrane | electrons |
| protons are depleted from the matrix and accumulate in the intermembrane space thereby creating a | proton gradient |
| A transmembrane enzyme called ______ couples the energy provided by the movement of these protons down their electrochemical gradient to synthesize ATP | ATP synthase |
| Though aerobic respiration is much more efficient, making up to 36-38 total ATPs per glucose molecule, some organisms live in environments where ______ is lacking | oxygen |
