Photosynthesis And Cellular Respiration. Photosynthesis

Photosynthesis and Cellular Respiration Photosynthesis and respiration are reactions that complement each other in the environment. In reality, they are the same reactions, but they occur in reverse. During photosynthesis, carbon dioxide and water yield glucose and oxygen. Through the respiration process, glucose and oxygen yield carbon dioxide and water. They work well because living organisms supply plants with carbon dioxide, which undergoes photosynthesis and produces glucose, and these plants and bacteria give out oxygen, which all living organisms need for respiration. Photosynthesis and respiration can be illustrated as follows: Photosynthesis Carbon Dioxide (CO2) + Water (6H2O) + Light energy Glucose (C6H12O6) +†¦show more content†¦During photosynthesis, glucose is produced from converted sunlight energy by plants. In general, the more light, the faster the rate of photosynthesis. However, research many years ago demonstrated that increased light intensity only increased the rate of photosynthesis up to a certain point. Therefore, the relationship of photosynthesis and cellular respiration is nonlinear (Biggs, Edison, Eastin, Brown, Maranville, Clegg, 1971). Scientific Method It is not uncommon for scientists to encounter a problem that cannot be explained. As a result, scientists use another fundamental process that is referred to as the scientific method. What is the scientific method? The scientific method is a way to probe into science by asking questions in a systematic way, which generates a hypothesis with the ultimate goal of improving the understanding of the problem. The following are the steps of the scientific method: Background and observation Generate a hypothesis Conduct an experiment based on the hypothesis Data analysis and results Share your conclusions with the scientific community Question: Is it possible to examine the relationship between photosynthesis and cellular respiration under controlled experimental conditions? Explain your response in detail. Model Answer It is not uncommon for scientists to encounter a problem that cannot be explained. As a result, scientists use another fundamental process that isShow MoreRelatedPhotosynthesis and Cellular Respiration2133 Words   |  9 PagesIntroduction Cells are the basic units of life and their processes are vital to the functioning of all organism. The reactions of photosynthesis and cellular respiration are complimentary and are also the most important pathways on the Earth. Photosynthesis is a process that converts carbon dioxide into organic compounds in presence of sunlight. Cellular respiration is the set of metabolic reactions that take in cells of living organisms that convert nutrients like sugar into energy , which is knownRead MoreCellular Respiration Vs. Photosynthesis844 Words   |  4 PagesOption 1: Cellular Respiration vs. Photosynthesis All life requires energy on a cellular level to survive and flourish. On our planet this is achieved by inter-dependent processes called cellular respiration and photosynthesis. In my discussion post I will explain how the processes of cellular respiration and photosynthesis occur, why the two processes are vital to life on earth, and I will discuss their similarities and differences. Discussion Cellular respiration is the method by which an organismRead MoreThe Stages of Cellular Respiration and Photosynthesis Essay581 Words   |  3 PagesThe Cellular respiration and photosynthesis form a critical cycle of energy and matter that supports the continued existence of life on earth. Describe the stages of cellular respiration and photosynthesis and their interaction and interdependence including raw materials, products, and amount of ATP or glucose produced during each phase. How is each linked to specific organelles within the eukaryotic cell? What has been the importance and significance of these processes and their cyclic interactionRead MoreEssay about Compare Photosynthesis and Cellular Respiration641 Words   |  3 PagesBoth photosynthesis and cellular respiration are the main pathways of energy transportation in organisms. However, the reactants and the products are exact opposites in photosynthesis and in cellular respiration. In photosynthesis, cells take in carbon dioxide (CO2) and water (H2O) by absorbing energy from the sun, and then the cells release oxygen (O2) and store glucose (C6H12O6). The formula of photosynthesis is: Light energy 6CO2+6H2O → C6H12O6+6O2 Read MoreEnergy, Metabolism, and Cells – Photosynthesis Cellular Respiration1026 Words   |  5 PagesBiology – Science 206 Energy, Metabolism, and Cells – Photosynthesis amp; Cellular Respiration John Carter August 11, 2013 1. Explain how photosynthesis and respiration are linked in order to provide you with energy from the food you eat. Photosynthesis can be defined as the process that living organisms such as plants use to translate the sun’s energy into chemical energy. Once the plant has translated the sun’s energy into chemical energy it then releases that energy and makes itRead MoreCPR 1 Jake Liang The purpose to cellular respiration and photosynthesis are to provide energy to600 Words   |  3 PagesCPR 1 Jake Liang The purpose to cellular respiration and photosynthesis are to provide energy to both animal and plant cells. In photosynthesis, chloroplasts use carbon dioxide and light and produce glucose and oxygen, while in cellular respiration, the animal cell uses glucose and oxygen to produce carbon dioxide, water, and energy; which is the opposite of what chloroplasts do. The location of cellular respiration differ, the materials and products of each are opposites of one another, the differentRead MoreWorld War Ii Through the 1970s627 Words   |  3 PagesElectron Transfer | 4. | ATP + NADPH | 5. | Calvin cycle | 6. | Glucose and O2 | 7. | Glycolysis | 8. | Pyruvic acid | 9. | Krebs cycle | 10. | ATP, H2O and CO2 | 1.What is the importance of the light and dark reactions in photosynthesis? In light reactions, light is absorbed by chlorophyll in the thylakoid membrane and energizes the electrons. ATP is created from ADP and P. NADP accepts electrons and turns in to NADPH, which is energy.

Organic compounds such as glucose store energy in their arrangements of atoms. These molecules are broken down and their energy extracted in cellular respiration. The first stage of cellular respiration occurs in the cytosol, while the second and third stages occur in mitochondria. In cellular respiration, electrons are transferred from glucose to coenzymesRead MoreThe Stages Of Cellular Respiration1611 Words   |  7 PagesRespiration Photosynthesis Cycle There are three stages of cellular respiration. Those stages are glycolysis, the citric acid cycle, and the electron transport. During glycolysis, a molecule of glucose is part into two molecules of a compound called pyruvic acid. The compounds for glycolysis are situated in the cytoplasm. The citric acid cycle also called the Krebs cycle finishes the breakdown of glucose the distance to CO2, which is then discharged as a waste product. The compounds for theRead MoreThe Effect Of Light Intensity On Photosynthetic Rates1553 Words   |  7 Pagesorganisms need to have a source of energy. Photosynthesis is the process by which plants use light energy and simple molecules to make chemical energy. The majority of all living things on earth benefit either directly or indirectly from the ability of photoautotrophs to do photosynthesis. Plants provide oxygen to Earth’s atmosphere and all animals, including humans, depend on plant material for food or to feed the food that they ul timately consume. Photosynthesis takes place inside the chloroplasts of
