Photosynthesis CAPTURING THE ENERGY IN LIGHT All organisms use energy for the functions of life. Many organisms use energy directly from sunlight. They capture part of the energy in light and store it within organic compounds.  The process by which this energy transfer takes place is called PHOTOSYNTHESIS.

Some of the energy stored in organic Compounds is released by Cells. CELLULAR RESPIRATION Some of the energy stored in organic Compounds is released by Cells. This is known as CELLULAR RESPIRATION.  Both Autotrophs and Heterotrophs Perform Cellular Respiration.

EQUATION FOR PHOTOSYNTHESIS WATER OXYGEN 6CO2 + 6H2O + Light Energy C6H12O6 + 6O2 CARBON DIOXIDE GLUCOSE

EQUATION FOR Cellular RESPIRATION CARBON DIOXIDE ATP GLUCOSE C6H12O6 + 6O2 6CO2 + 6H2O + ENERGY OXYGEN WATER

FOR ENERGY LIFE PROCESSES 1. ENERGY is the ability to do WORK or cause change. 2. Work for a Cell includes Growth and Repair, Active Transport, and Reproduction.  All which require ENERGY. 3. The source of Energy for ALL Organisms is FOOD, but different kinds of Organisms get their food in different ways.

4.  Plants, algae, and some prokaryotes (Bacteria) are all types of Autotrophs. 5. Only 10 percent of the Earth's 40 million species are Autotrophs. 6. Without Autotrophs, all other living things would DIE.  Without PRODUCERS you cannot have CONSUMERS. 7. Autotrophs not only make Food for their own use, but STORE a great deal of Food for use by other organisms (CONSUMERS).

8. Most AUTOTROPHS or PRODUCERS use PHOTOSYNTHESIS, to Convert the Energy in SUNLIGHT, CARBON DIOXIDE, AND WATER  into Chemical Energy OR FOOD.  (GLUCOSE) 9. THE FOODS MADE BY AUTOTROPHS ARE stored in various Organic Compounds, primarily CARBOHYDRATES, including a SIX-CARBON SUGAR called GLUCOSE.

10. Most Autotrophs use ENERGY from the SUN to make their food, but there are other organisms deep in the ocean that obtain Energy from INORGANIC COMPOUNDS. (CHEMOSYNTHESIS) 11. Organisms that CANNOT Make their own food are called HETEROTROPHS OR CONSUMERS. 12. Heterotrophs include animals, fungi, and many unicellular organisms, they stay alive by EATING AUTOTROPHS or other HETEROTROPHS.

13. Because Heterotrophs must consume other organisms to get Energy, they are called CONSUMERS. 14. Only part of the energy from the Sun is Used by Autotrophs to make Food, and only part of that Energy can be passed on to other Consumers. A Great Deal of the Energy is LOST as HEAT. 15. Enough Energy is passed from Autotroph to Heterotroph to give the Heterotroph the Energy it needs.

16. Photosynthesis involves a COMPLEX SERIES of Chemical Reactions, in which the PRODUCT of One Reaction is Consumed in the Next Reaction. 17. A Series of Reactions linked in this way is referred to as a BIOCHEMICAL PATHWAY. 18. Autotrophs use biochemical pathways of photosynthesis to manufacture organic compounds from Carbon Dioxide (CO2), and Water.  During this conversion, molecular OXYGEN(O2), is Released.

CELLULAR RESPIRATION 19. Some of the energy stored in organic Compounds is Released by Cells in another set of Biochemical Pathways, Known as CELLULAR RESPIRATION.  20. Both Autotrophs and Heterotrophs Perform Cellular Respiration. 21. During Cellular Respiration in Most Organisms, Organic Compounds are Combined with O2 to Produce ADENOSINE TRIPHOSPHATE or ATP, Yielding CO2 and Water as Waste Products.

22. The PRODUCTS of Photosynthesis, ORGANIC COMPOUNDS and O2, are the REACTANTS used in CELLULAR RESPIRATION. 23. The WASTE PRODUCTS of CELLULAR RESPIRATION, CO2 and WATER, are the REACTANTS used in PHOTOSYNTHESIS.
