Cellular Energy
| Question | Answer |
|---|---|
| Main goal of photosynthesis | convert light energy into glucose |
| Main goal of cellular respiration | convert glucose into ATP |
| Stores energy in carbon bonds and can be transferred from cell to cell | glucose |
| Stores energy in a phosphate bond and is used by the cell for cell processes | ATP |
| Where photosynthesis occurs | chloroplast |
| Where aerobic respiration occurs | mitochondria |
| Where anaerobic respiration occurs | cytoplasm |
| Inputs/Reactants for photosynthesis | light, water, carbon dioxide light + H2O + CO2 |
| Inputs/Reactants for aerobic respiration | oxygen, glucose O2 + C6H12O6 |
| Inputs/Reactants for anaerobic respiration | glucose C6H12O6 |
| Outputs/Products for photosynthesis | oxygen, glucose O2 + C6H12O6 |
| Outputs/Products for aerobic respiration | energy, water, carbon dioxide 36 ATP + H2O + CO2 |
| Outputs/Products for anaerobic respiration - plants and yeast | energy, carbon dioxide, alcohol (ethanol) 2 ATP + CO2 + ethanol |
| Types of cells that can do photosynthesis | Plants only |
| Types of cells that can do aerobic respiration | All eukaryotes - plants, animals and fungus |
| How is ADP different from ATP? | ADP has one less phosphate and stores less energy |
| When is energy released from ATP? | A chemical bond is broken between the second and third phosphate |
| When is energy stored in ATP? | A chemical bond is formed on the second phosphate of ADP and a third phosphate is added |
| Stages of aerobic respiration | Glycolysis, Kreb's cycle, Electron transport chain GKE-123 |
| Stages of photosynthesis | Light dependent reactions and Light independent reactions (Calvin cycle) |
| Site of glycolysis | cytoplasm |
| What is glycolysis? | Splitting of glucose - first step of respiration |
| Stage of photosynthesis that uses carbon dioxide (CO2) | Light independent (Calvin cycle) Calvin converts the carbons |
| Stage of photosynthesis that uses water (H2O) and light | Light dependent Lights splits the water |
| Which process? 6O2 + C6H12O6 --> 6H2O + 6CO2 + energy | aerobic cellular respiration formula |
| Which process? 6H2O + 6CO2 + energy --> 6O2 + C6H12O6 | photosynthesis formula |
| Muscles under anaerobic conditions produce? | lactic acid |
| Yeast undergoing fermentation produce? | carbon dioxide (CO2) and alcohol (ethanol) |
| Plants placed in anaerobic conditions produce? | carbon dioxide (CO2) and alcohol (ethanol) |
| Bacteria performing fermentation produce? | lactic acid |
| Outputs/Products for anaerobic respiration - bacteria and animals | energy, lactic acid 2 ATP + lactic acid |
