Photosynthes

The process of photosynthesis is a chemical reaction. It is the most important chemical reaction on our planet as far as most life is concerned. The process of photosynthesis is the changing of light energy to chemical energy. This energy is stored as sugar. This occurs in plants and some algae. Plants need CO2 and H2O. Photosynthesis takes place in chloroplasts, using chlorophyll, the green pigment in plants. What happens in this chemical reaction? A plant uses energy from the sun to combine carbon dioxide with water. It produces a sugar(glucose) and the plant gives off oxygen. The plant stores the energy from the sun in the chemical bonds of the sugar molecule.

6CO2 + 6H2O -> C6 H12 O6 + 6O2

Cellular Resperation

The process of cellular respiration is a chemical reaction. It is the most important reaction in our bodies. Cellular respiration is a process, like photosynthesis. Cellular respiration takes place in the mitochondria. The mitochondria take in nutrients, break them down, and create energy for the cell. This process of creating cell energy is known as cellular respiration. Takes place in all living things even plants. Cellular respiration is basically the reverse of photosynthesis. An animal takes in Glucose and Oxygen. The sugar is broken down into Carbon Dioxide and Water. When the chemical bonds in the glucose are broken there is a release of energy. The organism uses that energy. This process of creating cell energy is known as cellular respiration. Takes place in all living things.
