PPT-Carbon Cycle Photosynthesis

By E B Description of P hotosynthesis Photosynthesis enables plants to take in CO2 from the atmosphere and combine it with water Using the energy of the sun plants make sugar and oxygen molecules from the carbon dioxide. Light Independent Reactions. Can occur in the . absence. of light. Energy that was stored in ATP and NADPH during the light reactions is used to produce organic compounds in the form of sugars. Carbon fixation. . Part II of Photosynthesis. Calvin . Named after American biochemist Melvin Calvin. Most commonly used pathway by most plants. Calvin cycle is used by plants that are called C3 because of the 3-Carbon molecules that are made. Autotrophs. :. Organisms that are capable of producing/creating their own food. Photoautotrophs. – sunlight drives the energy production process. Chemoautotrophs. – can extract energy from an inorganic substance. Define Photosynthesis. The process by which plants manufacture (make) carbohydrates from raw materials using energy from the light.. Word and Chemical equation of Photosynthesis. 6CO. 2. + 6H. 2. O . This . presentation . was prepared by the University of Melbourne for the Regional Landcare Facilitator training funded through the Australian Government’s Carbon Farming Initiative Communications Program . Free Energy – .  . Enthalpy. . (heat of reaction) is the amount of energy released or absorbed during a chemical reaction . Symbol is . Δ. H. Think of it as energy . needed. Entropy. is a measure of randomness, tendency toward disorder. Why Study Photosynthesis?. *All food webs start with photosynthesis!*. Photosynthesis is arguably the most important biological process on earth because of two key chemical reactions. Liberating oxygen:. ∞. Plants and animals are linked for survival through the carbon dioxide-oxygen cycle.. Photosynthesis. To undergo photosynthesis, plants need:. sunlight. water. carbon dioxide. Carbon Dioxide. Photosynthesis. . N. CYCLE. CO. 2. THE CARBON CYCLE. CO. 2. CARBON DIOXIDE. Label the . processes. . of the carbon cycle.. CONSUMER. DETRITUS. FOSSIL FUELS. 1). petroleum/oil. peat. natural gas. coal. 2. ). 3. ). 4. Photosynthesis. . converts light energy from the sun into chemical energy in the form of organic compounds through a series of reactions known as . biochemical pathways. . . Autotrophs. . use energy from sunlight or from chemical bonds in inorganic substances to make organic compounds. . Chapter . 10. : Photosynthesis. From Topic . 2.9. Essential idea: . Photosynthesis uses the energy in sunlight to produce the chemical energy needed for life. .. Nature of science: . Experimental design—controlling relevant variables in photosynthesis experiments is essential (3.1).. Happens in the CHLOROPLAST. Using the chemical - Chloroplast. Only need to learn terms . Thylakoid. Granum. Thylakoid. Little . sacklike. things. Hold the chlorophyll. Like little solar panels. The stacks of Thylakoids are Granum/grana. C. 4 . Photosynthesis and CAM . Photosynthesis. 2. 3. Calvin Cycle Reactions:. Carbon Dioxide Fixation. CO. 2. is attached to 5-carbon RuBP molecule. Result in a 6-carbon molecule. This splits into two 3-carbon molecules (3PG). Science. Lesson 11: challenge answer . Find out the importance of carbon dioxide in the atmosphere. . Carbon dioxide traps heat in the atmosphere which is needed for our earth to be habitable. Otherwise, earth would be a frozen world. .
