Photosynthesis & Res
Photosynthesis & Res.
| 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 |
| Living organisms maintain a constant balance of two opposing sets of metabolic reactions called what? | Catabolic and anabolic pathways |
| All living organisms some kind of what? | Cellular Respiration |
| What is 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 cellular respiration can be divided into? | Aerobic and anaerobic |
| What is aerobic respiration? | Uses molecular oxygen as the final electron acceptor in the pathway |
| What is anaerobic respiration? | Does not use oxygen while it performs respiration |
| What is the anaerobic respiration formula? | C6H12O6 + 6O2 + 6H2O → 6CO2 + 12H2O + energy (ATP) |
| What is the formula for photosynthesis? | CO2 + 12H2O + energy (light) → C6H12O6 + 6O2 + 6H2O |
| What are the 4 stages aerobic respiration can be divided into? | Glycolysis, the formation of acetyl CoA, the citric acid cycle, and oxidative phosphorylation |
| What is glycolysis and where does it take place? | Involves the conversion of glucose into 3 carbon molecule of pyruvate and it takes place in the cytosol of cells |
| The formation of acetyl CoA involves what? | The conversion of each pyruvate acetyl CoA releasing one CO2 |
| The citric acid cycle does what? | Oxidizes the remaining carbon atoms of acetyl CoA to CO2 |
| What is the electron transport chain? | A series of membrane complexes that transfers energy-rich electrons from one complex to another in a chain |
| A pathway present in some prokaryotes is called what? | Anaerobic respiration |
| What happens during fermentation? | The reactions of glycolysis still occur making 2 ATPs |
| What happen during photosynthesis? | Light energy is converted into an organic molecule form such as glucose |
| What are the two stages that photosynthetic pathway can be divided into? | The light dependent reactions and the carbon fixation reactions |
| The light dependent reaction occurs where? | Within the thylakoid membrane of the chloroplast |
| What is the carbon fixation reactions also called? | The Calvin Cycle |
| Photorespiration reduces what? | The efficiency of photosynthesis |
| Rubiso turn CO2 into what? | Ribulose bisphosphate |
| Photophosphorylation Converts light into what? | ATP and NADPH |
