Respiration and Photosynthesis

Respiration and Photosynthesis All life depends on two chemical replys Respiration and Photosynthesis. These two outgrowthes argon quite crucial because they ar a source to securely all life on Earth. Both of these puzzle outes are quite alike(p) yet differentiate vastly. In this essay Ill be comparing and contrasting Photosynthesis and Respiration. Ill start by discussing what actually happens in both these processes and how? Moving on to the energy transfers these processes go finished and how these reactions relate to separately new(prenominal)wise.Plants feed using a process called Photosynthesis. Photosynthesis is the chemical change which happens in the leaves of green plants. Its the first ill-treat towards make food non just for plants but ultimately all animal on the planet. During this reaction carbondioxide and piddle are converted into glucose and oxygen. For this reaction to occur both carbon and nitrogen are absorbed from the root as nitrate and so is ca rbon as carbondioxide from the air and it withal wishs energy as the reaction is endothermic, therefore the energy is well-to-do from the sun.This is absorbed by a green substance called chlorophyll in the leaf. Therefore, photosynthesis takes place in the chloroplasts which are present in the palisade cells (found near the top of the leaf. ) (fig 1 ) As chloroplasts contain a green paint called chlorophyll, which absorbs comfortable energy needed to make photosynthesis happen. The equation for this reaction is 6CO2 + 6H2O+ lax energy C6H12O6 + 6O2Sugars created in photosynthesis butt end be later converted by the plant to starch for storage, or it can be combined with other sugar molecules to form specialized carbohydrates such as cellulose, or it can be combined with other nutrients such as nitrogen, phosphorus, and sulfur, to build mixed molecules such as proteins and nucleic acids. Moreover, cellular public discussion is reversibly related to photosynthesis because it takes in light energy and respiration gives out energy, which is used by the body as the glucose is converted into starch or stored.Oxygen is consumed unlike in photosynthesis, although in respiration energy is released in a more controlled and manageable way. During photosynthesis water and carbondioxide are chemically combined to make glucose and oxygen. The equation as follows C6H12O6 + 6O2 6CO2 + 6H2O In addition, respiration and photosynthesis are both processes which depend on each other on a very wide scale. Fig 2 explains this. (Fig 2 ) Shows a steering wheel and how photosynthesis and respiration are dependent on each other.As the leaf farms oxygen through photosynthesis and then that oxygen is inhaled by an animal. Later, the animal breathes out carbondioxide, and that is then absorbed by the plants through leaves by the air, in order for respiration to happen making this ongoing cycle continue. Though photosynthesis only takes place in leaves of plants (inside palisade cells) during the presence of light, respiration takes place in every living organism inside the mitochondria of the cell, with or without light being present or not.As all cells need energy through the sugar they made in their leaves oxygen moves through diffusion through the plant from cell to cell. Any oxygen not used by the plant in respiration, leaves the plant through petite holes under the leaf called stomata. Thats then part of the air we breathe, making the whole process start again. Thats how closely photosynthesis and respiration are linked to each other. Whilst, both respiration and photosynthesis are quite similar yet unlike at the same time. Respiration is a process by which energy is liberated.On the other hand photosynthesis is a social function where energy is stored in carbohydrate molecules as in, photosynthesis is an anabolic (constructive) process, resulting in the make up of carbohydrate molecules. While in respiration a catabolic (destructive) process occu rs, resulting in the breakdown of carbohydrate molecules. So, respiration results in a loss in dry mass where photosynthesis is totally the opposite, it results in a gain in ordinary mass. Furthermore, there are enzymes involved in the process of respiration.Enzymes are biological catalysts that speed up a reaction. The natural compounds that are broken down are substrates. Glucose is the most common substrate. The popular equation for respiration is C6H12O6 + 6O2 6CO2 + 6H2O + 38ATP During respiration, glucose undergoes glycolysis forming pyruvic acid. Glycolysis consists of nine separate chemical reactions, each catalysed by a specific enzyme. The key players in glycolysis are the enzymes dehydrogenase and a coenzyme (a non-protein helper). So, in photosynthesis is catalysed by chlorophyll.To summarize, photosynthesis takes the raw ingredients of water, carbondioxide and uses light to make glucose and oxygen. Despite, respiration uses glucose and oxygen to produce carbondioxide and water as waste products. Both these processes takes place in cells bar respiration takes place in the mitochondria of a cell. Photosynthesis is catalysed by chlorophyll acting in concert with lipids or sugars, while in respiration dehydrogenase is used. Nevertheless, photosynthesis and respiration both are a part of an ongoing cycle and snuff it together in order for plants or animals to survive.
