Question | Answer |
1.catabolic pathways | those that break down organic molecules for energy |
2.anabolic pathways | those that build up organic molecules to store energy for later use. |
3.cellular respiration | chemical pathway in which organic molecules are broken down to release energy in a quickly usable form (ATP) |
4.anaerobic respiration and fermentation. | Anaerobic pathways do not use oxygen as they perform respiration |
5.Aerobic Respiration | C6H12O6 + 6O2 + 6H2O → 6CO2 + 12H2O + energy (ATP) |
6.Photosynthesis | 6CO2 + 12H2O + energy (light) → C6H12O6 + 6O2 + 6H2O |
7.Glycolysis | is the first stage of aerobic respiration, but it is also a part of all other known cellular respiration pathways |
8.The formation of acetyl CoA | involves the conversion of each pyruvate into acetyl-CoA, releasing one CO2 for each pyruvate reactant |
9.The citric acid cycle | The citric acid cycle oxidizes the remaining carbon atoms of each acetyl-CoA to CO2 |
10.electron transport chain (ETC) | In the final stage, oxidative phosphorylation, NADH and FADH2 deliver their energy-rich electrons into the electron transport chain (ETC) |
11.Anaerobic respiration | a pathway present in some prokaryotes, is remarkably similar to aerobic respiration |
12.fermentation | Another alternative to aerobic respiration |
13.Photosynthesis | Generally speaking, photosynthesis is the opposite of respiration |
14.light-dependent reactions | The light-dependent reactions occur within the thylakoid membrane of chloroplasts |
15.carbon fixation reactions | The carbon fixation reactions, also called the Calvin cycle, use the energy in ATP and NADPH to synthesize glucose |
16.Calvin cycle | The carbon fixation reactions, also called the Calvin cycle, use the energy in ATP and NADPH to synthesize glucose |
17.rubisco | An enzyme called RuBP carboxylic/oxygenate, or Rubicon, incorporates CO2 into ribosomes bis phosphate (RuBP). |
18.photorespiration | Believed to be an evolutionary leftover, photorespiration sometimes reduces the efficiency of photosynthesis. |
19.During carbon fixation, the CO2 is | reduced by the NADPH molecules and the energy for these endergonic (energy-requiring) reactions is provided by ATP |
20.In plants, the glucose molecules are | often combined into a polymeric form called starch for longer-term storage. |
21.The rubisco enzyme will combine O2 (instead of CO2) with | RuBP when CO2 levels become particularly low. |
22.C4 and CAM plants are | species that have evolved to avoid photorespiration in environments that are especially dry and hot (where photorespiration is more likely to be a problem). |
23.In fermentation, the reactions of glycolysis still | occur, making 2 ATPs by substrate-level phosphorylation |
24.A transmembrane enzyme called ATP synthase couples the | energy provided by the movement of these protons down their electrochemical gradient to synthesize ATP |
25.In photophosphorylation, energy-rich electrons are | passed through a chain of electron carriers which causes protons to be pumped into the interior of the thlakoid, This proton gradient is used by an ATP synthase to make ATP. |
