Photosynthesis is the procedure where green plants use sunlight to manufacture foods from water and carbon dioxide. Photosynthesis uses chlorophyll and oxygen is created as a by-product (Wierdsma, Knippels, van Oers & Boersma, 2016). On the other hand, Cellular respiration involves a set of metabolic reactions and processes that are known to take place in an organism cell to transform the nutrients biochemical energy into adenosine triphosphate (ATP) (Wierdsma, Knippels, van Oers & Boersma, 2016). Photosynthesis makes the glucose that is needed in cellular respiration to make ATP. This glucose is then reversed back to carbon dioxide that is used in photosynthesis. Also, when water in photosynthesis is broken down to form oxygen, in cellular respiration the oxygen is combined with hydrogen to form water.
A significant relationship links photosynthesis and cellular respiration. The link allows life to endure as we understand. Moreover, the products of one process are the reactants of another process. Furthermore, the equation for the cellular respiration is the opposite in photosynthesis. Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O2 (Wierdsma, Knippels, van Oers & Boersma, 2016). Cellular respiration and photosynthesis are essential elements of the carbon cycle. The carbon cycle explains the ways through which carbon is recycled back into the atmospheres. Photosynthesis pulls carbon dioxide from the air while cellular respiration releases the carbon back into the air. Therefore, from the exchange of carbon and oxygen during the cell respiration and photosynthesis helps keep the carbon dioxide and oxygen levels at stable levels (Wierdsma, Knippels, van Oers & Boersma, 2016).
Delegate your assignment to our experts and they will do the rest.
Consequently, through the processes, it is possible to trace the sunlight proton (energy) from the sun to the point it hits the leaves. In the leaves, it combines with the glucose and carbon dioxide in the atmosphere to form photosynthesis. After that, the leaves are eaten by the giraffe and the energy attained is broken down by the giraffe’s cells through cellular respiration to produce the energy need by the giraffe to function. After the cell respiration, the giraffe releases carbon dioxide which is an essential ingredient in photosynthesis.
