| Question | Answer |
|---|---|
| Formula for photosynthesis (Reactants--> Products) | 6 CO2 + 6 H20 + Energy -> Glucose +6 O2 |
| Formula for Cellular Respiration (Reactants -> Products) | Glucose + 6 O2 -> 6 CO2 + 6 H2O + 38ATP |
| ATP | Molecule of energy, needed by ALL organisms |
| Glycolysis | Glucose is converted in to 2 pyruvate + 2ATP in the cytoplasm |
| Krebs Cycle(aerobic) | Second step of cellular respiration where the pyruvares from glycolysis enter the mitochondrial matrix and with oxygen make 36ATP |
| Aerobic | With Oxygen |
| Anaerobic | Without oxygen |
| Fermentation (anaerobic) | When there is not enough oxygen the pyruvates from glycolysis get converted to less ATP and lactic acid(in the cytoplasm) |
| Light-Dependent Reaction | First step of photosynthesis when light is captured in the thylakoid of chloroplasts |
| Light-Independent reaction (Calvin Cycle) | Second step in photosynthesis where light energy is converted into carbohydrates(glucose) takes place in the stroma of chloroplasts |
| Where does glycolysis take place | Cytoplasm |
| Where does Krebs cycle take place | In the Matrix of the mitochondria |
| Where does fermemtation take place? | In the cytoplasm |
| What are the products of photosynthesis? | Glucose and Oxygen |
| What are the products of cellular respiration? | Carbon dioxide, water, and 38ATP |
| Where does the pain associated with too much exercise come from? | Lactic acid build up |
| T/F Water is a product of cellular respiration | True |
| C6H12O6 (aq) + 6 O2 (g) → 6 CO2 (g) + 6 H2O (l) + 38 ATP | CEllular Respiration |
| T/F Glucose is a reactant of cellular respiration | True |
| Name the two reactants of cellular respiration | Glucose + Oxygen |
| Name the three reactants of photosynthesis | Water, carbon dioxide and Sun's energy |
| 6H2O + 6CO2+ Light Energy ----> C6H12O6+ 6O2 | Photosynthesis |
| What two things are produced by photosynthesis? | glucose and oxygen |
| What's another word for sugar? | Carbohydrates, sacchirides |
| What is the carbohydrate monomer broken up during cellular respiration? | Glucose |
| How does a heterotroph obtain energy? | It eats another organism |
| How does an autotroph obtain energy? | It produces it (photosynthesis) |
| What are the two steps of cellular respiration? | 1. Glycolysis(cytoplasm)2. Krebs cycle(matrix of mitochondria) |
| Why would the cells in a heart need more mitochondria? | Need constant supply of energy (ATP) |
| In the absence of oxygen the pyruvates will enter this pathway | Fermentation |
| What does a chloroplast have in common with a mitochondria? | They both have circular DNA (plasmid) and ribosomes |
| The Calvin cycle is the second step of ________. | Photosynthesis |
| The Krebs cycle is the second step of ________. | Cellular respiration |
| Where are carbohydrates synthesized? | In the stroma of chloroplast, in autotrophs |
| What is another word for carbohydrate synthesis? | Calvin Cycle |
| Where is glucose broken down? | IN the cytoplasm, through glycolysis |
