Photosynthesis and Cellular Respiration

PHOTOSYNTHESISMost important biological process on earthFills food requirements & needs for fiber & building materialPetroleum, natural gas, coal, firewoodPhoto means lightSynthesis means to put togetherPhotosynthesis happens in the chloroplast in plants, some bacteria, and some protists.

The Equation Reactants Products

Carbon dioxide + Water sunlight Glucose + Oxygen(carbohydrate)

6CO2 + 6H20C6H12O6 + 6 02

Cellular RespirationTakes place day and night in all living cellsplants, animals, protists, bacteria, and fungi.Step-by-step breakdown of high-energy glucose molecules to release energy (ATP)All living things take in food and oxygen to produce energy in the cell using cellular respiration.

Where does it happen? In the CellMitochondriapowerhouse of the cell

Steps in cellular respirationSugar (glucose= C6H12O6 ) from food is eaten. Oxygen (02 ) is inhaled (breathed in from the water in some organisms). Food is broken down with the help of oxygen through body chemical reactions (metabolism).Carbon dioxide (CO2 ) and water (H20 ) are exhaled.

36 are produced in the reaction, which is energy needed for cellular activity. ATPThe equation Reactants Products

Glucose + Oxygen Carbon dioxide + Water + Energy (carbohydrate)6CO2 + 6H20+C6H12O6 + 6 02


MITOCHONDRION (IN THE CELL)Comparing both processesYou can say that the formulas for photosynthesis and cellular respiration are the exact opposite:Photosynthesis:

Cellular Respiration:

6CO2 + 6H206CO2 + 6H20ATPC6H12O6 + 6 02C6H12O6 + 6 02NOTE: ATP is produced in both reactions, but CELLULAR RESPIRATION produces all the ATP needed for cells to function.
