1 Photosynthesis and Respiration
Cell Processes Photosynthesis and Respiration

2 Photosynthesis Nearly all living things get their energy either directly or indirectly from energy of sunlight.

3 An organism that makes its own food.
Autotrophs An organism that makes its own food.

4 Heterotrophs Organism that cannot make its own food.

5 Two Stages of Photosynthesis
Capturing the sun’s energy Chlorophyll- the green pigment in plants that captures the sun’s energy. Found in the chloroplasts of a plant cell. 2. Using Energy to Make Food With water and carbon dioxide to make glucose (sugar) to use as food.

6 Equation for Photosynthesis
6CO2 + 6H2O > C6H12O6 + 6O2

7 Respiration During respiration cells break down simple food molecules such as sugar and release the energy they contain This occurs in the mitochondria of all cells.

8 Stage One In the cytoplasm, glucose is broken down into smaller molecules and a small amount of energy is released.

9 Stage Two In the Mitochondria, the smaller molecules combine with oxygen to produce water and carbon dioxide, this reaction releases a large amount of energy

10 You can think of photosynthesis and respiration
as opposite processes
