| Question | Answer |
| Living organisms maintain a constant balance of two opposing sets of metabolic reaction called... | Catabolic pathways and anabolic pathways |
| Catabolic pathways | Those that break down organic molecules for energy |
| Anabolic pathways | those the build up organic molecules in store energy for later use |
| All living organisms perform some kind of ___________ ____________. | Cellular respiration |
| Cellular respiration | A chemical pathway in which organic molecules are broken down to release energy in a quickly usable from (ATP) |
| What are the two basic categories cellular respiration can be divided into? | Aerobic respiration and anaerobic respiration |
| Aerobic respiration | uses molecular oxygen as the final electron acceptor in the reaction pathway. |
| Anaerobic pathways | Do not use oxygen as the perform respiration |
| Does fermentation use oxygen as it performs respiration? | No |
| Aerobic respiration can be divided into 4 stages. What are the four stages? | Glycolysis, the formation of acetyl CoA, the citric acid cycle, and oxidative phosphorylation |
| How many ATPs per glucose molecule does aerobic respiration make? | 36 - 38 |
| What's different between aerobic and anaerobic respiration? | Aerobic uses oxygen and anaerobic does not. |
| Photosynthesis | is the opposite of respiration. Light energy is converted into an organic molecule form such as glucose. |
| What are capable of performing photosynthesis? | Plants, algae, and some kinds of bacteria. |
| Why cant animals perform photosynthesis? | It's because their cells do not contain chloroplasts |
| The photosynthetic pathway can be divided into two stages called... | Light dependent reactions and the carbon fixation reactions |
| Light-dependent reactions | Occurs in the thylakoid membrane of chloroplast. |
| Carbon fixation reactions is also called the _______ __________ | Calvin cycle |
| Carbon fixation reactions | uses the energy in ATP and the NADPH to synthesize glucose. |
| What does rubisco do? | It incorporates CO2 into Ribulose bisphosphate (RuBP) |
| During carbon fixation, the CO2 is _________ by the NADPH molecules and the energy for the energy requiring reactions is provided by ATP | reduced |
| What does photorespiration sometimes do? | It sometimes reduces the efficiency of photosynthesis. |
| The anaerobic process that is essential for making bread, cheese, ethyl alcohol, and some pharmaceuticals is called? | Fermentation |
| Yeast contained in bread dough completes anaerobic respiration and causes the bread to rise. Which gas released by the yeast causes the bread to rise? | Carbon dioxide |
