1Photosynthesis and Respiration Cell ProcessesPhotosynthesis and Respiration
2PhotosynthesisNearly all living things get their energy either directly or indirectly from energy of sunlight.
3An organism that makes its own food. AutotrophsAn organism that makes its own food.
4HeterotrophsOrganism that cannot make its own food.
5Two Stages of Photosynthesis Capturing the sun’s energyChlorophyll- the green pigment in plants that captures the sun’s energy. Found in the chloroplasts of a plant cell.2. Using Energy to Make FoodWith water and carbon dioxide to make glucose (sugar) to use as food.
6Equation for Photosynthesis 6CO2 + 6H2O > C6H12O6 + 6O2
7RespirationDuring respiration cells break down simple food molecules such as sugar and release the energy they containThis occurs in the mitochondria of all cells.
8Stage OneIn the cytoplasm, glucose is broken down into smaller molecules and a small amount of energy is released.
9Stage TwoIn the Mitochondria, the smaller molecules combine with oxygen to produce water and carbon dioxide, this reaction releases a large amount of energy
10You can think of photosynthesis and respiration as opposite processes
