The Importance of Photosynthesis and Respiration Explain how photosynthesis and respiration are linked in order to provide you with energy from the food you eat: Photosynthesis is the process in which certain life forms are able to use sunlight to create energy. This energy is created by making carbohydrates from carbon dioxide and water in the presence of chlorophyll. Plants release large amounts of oxygen into the atmosphere as they produce much more than needed during the photosynthesis process

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. Once the light

Photosynthesis is the process by which plant cells capture and process the suns energy to make this energy available to all living things (Audesirk T, Audesirk G, Byers G, 2008). Photosynthesis controls all tropic chains and food on Earth. The photosynthesis process is described by the following equation: 6CO2 + 6H2O + Light Energy = C6H12O6 + 6O2. This equation means carbon dioxide from the air and water combine in the presence of sunlight to form sugars: oxygen is released as a by-product of

_____________ Period ______ Lab: Investigating Photosynthesis and Cellular Respiration Background: All organisms are dependent on a healthy carbon dioxide-oxygen balance. Photosynthesis and cellular respiration are key processes in maintaining this balance. Plants, through the process of photosynthesis, use energy absorbed from sunlight, water, and carbon dioxide to produce sugars and oxygen. Animals and plants, through the process of cellular respiration, use oxygen and sugars to produce carbon dioxide

Robinson, Alexis Downie BIOL 1441_Section 055; Corey Roelke; October 9, 14 Abstract: Photosynthesis is the process to receiving the sunlight energy of plants, algae and some bacteria to produce organic compounds to self-serving as food source for most organism on Earth (J. Stein Carter). Chemical energy stored in carbohydrates such as sugar molecules, and is synthesized from carbon dioxide and water. Photosynthesis helps to maintain the oxygen concentration in the air and provide all the organic compounds

stimuli, e.g. temperature, oxygen concentration and levels of sunlight. These may be over time, e.g. winter fur to summer fur, or quickly, e.g. changing size of pupils. Internal environments change too- the build up of carbon dioxide as a result of respiration changes the pH of the tissue fluid, and therefore inhibits enzyme activity. Multicellular organisms need to coordinate different organs, so this requires a good communication system which will: • Cover the whole body • Enable cells to communicate
