Photosynthesis is the process used by plants to convert light into useful chemical energy which, through bacterial respiration, is released into the soil to fuel the plant’s metabolism. Photosynthesis has been around since the beginning of plant life, when it was first noticed that materials which were composed of living matter could be transformed into some other form, even when no sunlight was present. Photosynthesis is also one of the three main theories on how life on earth began. All other theories believe that life began in the ocean, which eventually became the Earth and all that it has been through its long development since.
Photosynthesis occurs in nature as well as in man-made systems. Photosynthesis occurs in two different ways, either through the use of light energy to make the necessary chemical energy needed for the aerobic (oxygen-requiring) photosynthetic organisms, or in the non-oxygen-requiring Photosystems. Under the Photosynthetic theory, photosynthesis uses up energy from the sun to create food for the aerobic organisms and the Carbon Dioxide in the air absorbs the carbon dioxide to return the energy.
Photosynthetic enzyme, is a pair of riboszyme complexes which bind together with an amino acid (the simplest of the amino acids) to produce the sugar glucose. The process of Photosynthesis occurs in three stages, before it is complete, Photosynthetic Phase I, where the sugars are in solution, Photosynthetic Phase II, where the sugars are separated out into carbon dioxide and water, and the third stage, the Degradation, where the carbon dioxide is accumulated back into the solution. During Photosynthesis, the oxygen is taken up by the leaves, the roots, and the stems of the plants. The absorption of oxygen by the roots and the absorption of carbon dioxide by the leaves constitute the photosynthetic processes. These processes take place all over the world, and are the basis of all life.
In Photosynthesis, the assimilated light reactions produce heat energy. This heat energy is transferred to the roots and the other parts of the plants. The non-photosynthetic parts of the plant, such as the stamen, the pigment, and the exoskeletons, which do not consume energy, do not need to be converted into energy carrier molecules, since they are non-photoactive. They simply provide the plants with food and regulate the Photosynthesis reaction.
One of the basic functions of Photosynthetic enzymes is to recycle the light energy that has been absorbed by the carbohydrates in the plants. The sugar, depending on the type of carbohydrate, is then used by the autotrophs for the development of proteins and cells. The process of Photosynthesis is therefore a coordinated set of biochemical events that occur continuously within the living organisms.
Photosynthesis can be divided into two processes: Photosystems and Glycolysis. In Photosystems, the sugars are used for creating adenosine triphosphate or ATP. The use of adenosine triphosphate is necessary for the growth and development of a cell, and this is the basis of all cell function. When there is enough stored ATP, the cell can divide and grow into a greater number of cells. The use of the energy derived from the sun is the source of the sunlight that is necessary for Photosynthesis to take place.
On the other hand, in Glycolysis, the main source of energy is the utilization of the glucose. The photosynthesizing bacteria are able to break down the glucose present in green plants, and the use of the glucose creates energy for the bacteria. In Photosynthesis, the process takes place at a rate very close to the rate of evaporation. This means that Photosynthesis can actually take place at a slower rate than is required by the organisms.
It has been a great mystery for scientists how Photosynthesis works. However, the basic mechanism involved is that the photosynthesizing bacteria are able to use light to produce food for themselves and, in the process, the plants get their carbon dioxide back as their primary source of energy. However, it has been shown that in a much more efficient way than had been previously thought, Photosynthesis does not use up all of the carbon dioxide in the air, rather the plants only use a small amount, which is generally a drop in the ocean level.
