Module 03: Chemical Reactions in Photosynthesis & Respiration
| Question | Answer |
|---|---|
| True or False? The role of chlorophyll in photosynthesis is to combine with water to form oxygen. | False- Chlorophyll absorbs the light needed for photosynthesis. |
| Which of these substances is formed during photosynthesis? Carbon dioxide light sugar water | sugar |
| Which of the following is true about science? | Economic concerns may prevent it from solving problems. |
| What gas is formed during photosynthesis? | Oxygen |
| Photosynthesis uses the gas _____________________. | Carbon dioxide |
| Which of the following statements correctly identifies the role of substances during photosynthesis? | Oxygen is formed along with glucose during photosynthesis. |
| Which of the following statements correctly identifies the role of substances during photosynthesis? | Water combines with carbon dioxide during photosynthesis. |
| True or False? The role of oxygen in photosynthesis is to transform glucose into water. | False- Oxygen is formed along with glucose. |
| What happens to the matter that is used during photosynthesis? | It changes to a new form of matter with the same mass. |
| What happens to the energy that is used during photosynthesis? | It changes to an equal amount of chemical energy. |
| What is true about the mass of the products during photosynthesis? | They have the same mass as the reactants. |
| Using the balanced equation for photosynthesis, how would you prove the law of conservation of mass? 6 CO2 + 6 H2O → C6H12O6 + 6 O2 | By showing that the numbers of atoms of the same type are equal on both sides. Mass of the reactants= mass of the products |
| Which product is released during cellular respiration? | Carbon dioxide and water |
| What is the role of a glucose molecule during the process of cellular respiration? | It helps to release energy. |
| Where does cellular respiration take place in a cel? | Mitochondria (mighty Mitochondria) |
| Photosynthesis or Cellular Respiration? Which process takes place in both plant and animal cells? | Cellular respiration |
| Oxygen combines with carbon dioxide. Is this photosynthesis or cell respiration? | Photosynthesis |
| Glucose is broken down. Is this photosynthesis or cell respiration? | Cellular respiration |
| Energy is used up. Is this photosynthesis or cell respiration? | Photosynthesis |
| Simple sugars are formed. Is this photosynthesis or cell respiration? | Photosynthesis |
| Which of the following is a part of a water-based carbon cycle? | Crab shells |
| Which of the following is a part of a land-based carbon cycle? | Trees |
| The process that helps to cycle carbon between water and air is called ______________. | Diffusion |
| What process might impact the cycling of carbon between land and air? | Deforestation - less trees to cycle in carbon dioxide and cycle out oxygen. |
| Which of these processes releases carbon into the air? | Cellular Respiration |
| During which part of the carbon cycle would carbon most likely be stored? | Formation of fossil fuels |
| During which part of the carbon cycle would carbon most likely be released? | Burning of coal |
