| Question | Answer |
|---|---|
| What are catabolic pathways? | those that break down organic molecules for energy |
| What are anabolic pathways? | those that build up organic molecules to store energy for later use. |
| What is cellylar respiration? | All living organisms perform some kind of cellular respiration, a chemical pathway in which organic molecules are broken down to release energy in a quickly usable form (ATP). |
| What are the two categories for cellular respiration? | Cellular respiration can be divided into two basic categories, aerobic and anaerobic. |
| What are anaerobic pathways? | Aerobic respiration uses molecular oxygen (O2) as the final electron acceptor in the reaction pathway. Anaerobic pathways do not use oxygen as they perform respiration; |
| Aerobic respiration can be divided into 4 stages:What are the four stages? | Glycolysis;The formation of acetyl CoA;The citric acid cycle;Oxidative phosphorylation |
| What is the electron thansport chain/ | The electron transport chain is a series of membrane complexes that transfers energy-rich electrons from one complex to another in a chain. |
| What is anaerobic respiration? | Anaerobic respiration, a pathway present in some prokaryotes, is remarkably similar to aerobic respiration. |
| What is fermentatioN? | In fermentation, the reactions of glycolysis still occur, making 2 ATPs by substrate-level phosphorylation. |
| What is photosynthesis? | In photosynthesis, light energy is converted into an organic molecule form such as glucose. |
| What are light dependent reactions? | The light-dependent reactions occur within the thylakoid membrane of chloroplasts. |
| What is the carbon fixation reaction? | use the energy in ATP and NADPH to synthesize glucose |
| What is the carbon fixation reaction also called? | the Calvin cycle |
| What does rubisco do? | incorporates CO2 into ribulose bisphosphate (RuBP). W |
| What does photorespiration do? | photorespiration sometimes reduces the efficiency of photosynthesis |
| What is glycolysis? | Glycolysis is the first stage of aerobic respiration |
| What is the formation of acetyl CoA? | The formation of acetyl CoA involves the conversion of each pyruvate into acetyl-CoA, releasing one CO2 for each pyruvate reactant. |
| What does the citric acid cycle do? | The citric acid cycle oxidizes the remaining carbon atoms of each acetyl-CoA to CO2. |
| what is the formula for aerobic respiration? | C6H12O6 + 6O2 + 6H2O → 6CO2 + 12H2O + energy (ATP) |
| What is the formula for photosynthesis? | 6CO2 + 12H2O + energy (light) → C6H12O6 + 6O2 + 6H2O |
| What do living organisms do? | Living organisms maintain a constant balance of two opposing sets of metabolic reactions |
| What is the energy from the electrons used to do? | The energy from the electrons is used to pump protons across the inner mitochondrial membrane |
| How many ATPs does aerobic respiration have? | making up to 36-38 total ATPs per glucose molecule |
| WHy is the conversion of pyruvate necessary? | The conversion of pyruvate is necessary to regenerate the NAD+ needed for consecutive rounds of glycolysis. |
