Photosynthesis Essay

Photosynthesis Essay is the conversion of light energy to chemical energy which is thenstored in the form of glucose or other organic compounds. Photosynthesis occurs inplants, algae and certain prokaryotes.

Photosynthesis is generally the opposite ofrespiration where photosynthesis starts with CO2, light energy, and water to yield glucose,water and oxygen. This is the general equation for photosynthesis: 6CO2 + light energy +In plants photosynthesis occurs in the thylakoid membrane. There are tworeactions in the thylakoid membrane: the light dependent reactions, and the lightindependent reactions. In the light dependent reactions, light excites an electron into ahigher energy state. This electron is then captured by an electron acceptor and the energyreleased during it’s fall back down to ground state is harvested to create ATP.

In the lightindependent reactions, the energy made from the light dependent reactions is used to makeglucose, a six carbon sugar. The carbon comes form the break down of CO2 and theHowever, there are imperfections. Sometimes the light independent reactions usesO2 instead of CO2 which produces a two carbon compound. This compound is useless tothe plant and it uses more energy to break it back down to CO2.

The process where O2 isused instead of CO2 is called photorespiration. Plants which have a lot of photorespirationare known as C3 plants and are very slow growing. Fast growing plants, plants that havelittle photorespiration, are known as C4 plants. This experiment tested how much CO2 is consumed in C3 plants versus C4 plants. The null hypothesis is that in C3 plants will consume as much CO2 as C4 plants.

Thealternate hypothesis is that C4 plants will consume more CO2 because photorespiration isBibliography: .
