Photosynthesis is a long process but it is need for most life on planet earth. The byproduct of photosynthesis has oxygen in it, and is need for human survival as well as other animals to live on earth. The process for photosynthesis is long but is needed . There are two processes in which energy is made. One which includes oxygen and the other which does not include oxygen. Great amounts of energy or ATP is produced for all organisms to be able to survive and they are made by mostly plants. Photosynthesis is an everlasting occurrence as long as plants are living on this earth to be able to produceATP and oxygen. Chemical reactions and light are need for photosynthesis in the production of energy. In the process of photosynthesis green plants …show more content…
There are enzymes used to capture light pigments to help make the process faster. They are put into two different units; Photosystem I and Photosystem II. A single chloroplast can have lots of thylakoids and can have millions molecules of pigments. Photosynthesis which is long is separated into two different stages. Stage one is the light dependent reaction which takes light and converts it into NADPH and ATP. In stage two NADPH and ATP are used in the light independent reaction and NADPH gives hydrogen to form glucose and ATP gives energy to form glucose. Light energy is needed to starts the light dependent reaction (Dickson 199). Photosynthesis starts when light hits the Photosystem I pigments and starts the electrons. Energy moves from molecule to molecule to get to a chlorophyll molecule called P700, which absorbs red wavelengths at a range of 700 nanometers. P700 takes the energy to move electrons to the acceptor molecule to hold them. The electron are passed down the electron transport chain. The electrons are moved from a low level of energy to a high level of energy which releases the energy as they move down the chain. NADP+ comes together with a hydrogen to form NADPH (Dickson …show more content…
Photosynthesis is the cycle of changing sunlight into energy for all organisms. Plants convert CO2 to organic forms by reconstructing it with chemical reactions. The electrons are used for water molecules to be turned into oxygen. Light is needed for this process and is absorbed by pigments. The chlorophyll absorbs blue and red waves and the other colors of the spectrum pass through or are reflected by the leaves. This is why leaves are green in spring and summer and red, yellow, and purple in the fall. Lots of pigments are not able to absorb ultraviolet light because the wavelengths are smaller than 400nm and are undetectable by the human eye. The wavelengths that are under 330 nm the cells can get very damaged but these wavelengths are filtered through the atmosphere before reaching the surface of the earth. When plants have an overexposure to ultraviolet light there is a big effect on the plants and production (Vermaas
