| Question | Answer |
| What is the importance of the light and dark reactions in photosynthesis? | During the light reactions of photosynthesis, light energy from the sun is captured and used to make ATP and NADPH. During the dark reactions, ATP, NADPH, and carbon dioxide combine to make glucose and other compounds. | What happens to food energy during photosynthesis?2 | Food energy is stored in chemical bonds during photosynthesis.2 | What happens to food energy during cellular respiration?3 | Food energy is released by the breaking down of those bonds during cellular respiration.3 | Why is photosynthesis important to you?4 | Photosynthesis is perhaps one of the most primary processes for the survival of species that do not make their own food. Without photosynthesis, there would be no food production.4 | What are the processes in cellular respiration?5 | Glycolysis and the Krebs cycle are the processes in cellular respiration. During glycolysis, glucose is broken down into pyruvic acid. The pyruvic acid enters the Krebs cycle where it is broken down further and energy is produced.5 | Why are photosynthesis and cellular respiration viewed as complementary processes?6 | Photosynthesis and cellular respiration can be viewed as complementary processes because the product produced by each process is used by the other. During photosynthesis, H2O (water) and CO2 (carbon dioxide) and sun energy are used to produce O2 (oxygen) and glucose. During cellular respiration, O2 and glucose are used to produce H2O and CO2 and energy.6 | Describe the similarities and differences between photosynthesis and cell respiration.7 | In photosynthesis, food is synthesized and then stored as glucose, carbon dioxide is taken in, oxygen is given off, and the process requires light. In cellular respiration, food is broken down and the energy from glucose is released, oxygen is taken in, carbon dioxide and water are given off, and the process does not require light. Both photosynthesis and cellular respiration use cycles and electron transport.7 |
