Photosynthesis and cellular respiration make one large cycle that sustains life on earth. Through photosynthesis the suns energy is constantly being transformed into glucose, which is a chemical energy. Respiration is the chemical activity that occurs in all plants and animal cells that release the energy from the glucose. Photosynthesis cannot exist with cellular respiration, they are completely linked together in providing the energy through the food we eat. Cloud, D (2012). Photosynthesis and cellular respiration have an inverse relationship, they are opposite of each other. Photosynthesis is the process by which carbon dioxide is converted into compounds from the sunlight. The most frequent compound being glucose (sugar). Photosynthesis occurs in plants, algae, and some bacteria. Editorial Board (2014). Cellular respiration, in contrast takes the glucose (sugar) and other compounds oxidizing them to created carbon dioxide. Each cycle depends on the other in order for the completion to take place. The complete cycle ensures that life continues to exist, both being necessary for living organisms. Cloud, D. (2012). Photosynthesis is a natural process that provides all aerobic creatures on eth with oxygen. Without photosynthesis, humans would not be able to exist. Photosynthesis maintains the natural amount of oxygen in the air. It provides oxygen for life and the process of cellular respirations. Photosynthesis releases oxygen as a byproduct. The oxygen results from the splitting of water during the light reactions of photosynthesis. The oxygen released in the air can be used by organisms that respire aerobically to release energy stored in molecules, these organisms release water and carbon dioxide as a byproduct. The carbon dioxide is necessary for the synthesis of carbohydrates in the organisms. Cellular respiration can be defines as metabolic reactions in organic cells which converts

    Photosynthesis is a process to which some autotrophs such as plants produce their own food. It has two stages or reactions light-dependent and light-dependent reactions. The light dependent reactions are the first stage, where energy from sunlight is captures in Photosystem 2 and then 1, the electrons generated in Photosystem 1 then moves along the electron transport chain. The moving of electrons causes a hydrogen ion gradient that is used in the final step to produce ATP, by the ATP Synthase. The equation for this reaction is 6CO2 + 6H2O  C6H12O6+6O2 or, carbon dioxide +water sugars + oxygen . This reaction takes place on the thylakoid membrane of the chloroplast and uses energy from sunlight to produce compounds like ATP and NADPH. The second stage of photosynthesis is the Calvin Cycle, which takes place in the stoma of the chloroplast. This stage is light-independent or it does not need energy from sunlight. During this reaction ATP and NADPH from Stage 1are used to produce high energy sugars. The reaction is 3CO2 + 6NADPH + 5H2O + 9ATP  G3P + 2H+ + 6NADP+ + 9ADP + 8Pi . Additionally, the three limiting factors of photosynthesis are the light intensity, carbon dioxide concentration, and the temperature. Lastly, the items used in this particular experiment were baking soda to provide CO2, a light to excite the electrons in stage 1, distilled…

    To be able to carry on metabolic processes in the cell, cells need energy. The cells can obtain their energy in different ways but the most efficient way of harvesting stored food in the cell is through cellular respiration. Cellular respiration is a catabolic pathway, which breaks down large molecules to smaller molecules, produces an energy rich molecule known as ATP (Adenosine Triphosphate) and a waste product that is released as CO2. Basically, cellular respiration is a metabolic process that releases energy from organic compounds (such as C6H12O6) by metabolic chemical oxidation in the mitochondria within each cell. Proteins, carbohydrates, and fats can all be broken down into fuel for the cell but cellular respiration is usually correlated with glucose. Cellular respiration also requires O2 to carry out its pathway, as oxygen will act as a final electron acceptor. So, the final equation that can be represented for Cellular Respiration is: C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + heat.…

    Cellular Energetics is the broad term that encompasses both cellular respiration and photosynthesis and refers to how energy changes and reacts within cells. Cellular respiration is the process by which cells break down sugars (ATP) in order to produce energy for other chemical reactions. Cellular respiration takes place mainly in the mitochondria and the reactants in this process are oxygen and glucose and the main product in this process is ATP as well as waste products which include carbon dioxide and water. Almost all organisms perform cellular respiration. There are two types of cellular respiration…

    Explain how photosynthesis and respiration are linked in order to provide you with energy from the food you eat. To start off with we will need to define photosynthesis and respiration. Photosynthesis is a process in which carbon dioxide, water, and certain inorganic salts are converted into carbohydrates by green plants, algae and certain bacteria using energy from the sun and chlorophyll (dictionary.com). Respiration is all of the physical and chemical processes in an organism by which oxygen is conveyed to tissues, cells and the oxidation products carbon dioxide and water given off (dictionary.com). Aerobic respiration is a cellular respiration that requires oxygen too and order to help generate energy. The two processes which are photosynthesis and respiration are links plants and animals in different ways. Photosynthesis links the two through air. The reason being is because of the oxygen that is link out is use by the plants and animals to make respiration. The respiration than makes glucose which is used to help energy be reserved for period of darkness and to help and the structure of plants. When glucose comes about that is how sugar gets transferred into the human body.…

    Photosynthesis converts light received from the sun into chemical energy known as ATP. Visible light is absorbed by the pigments found in plants. Carbon dioxide and water synthesizes into glucose and oxygen. By doing so, the metabolic activity of cells is powered. It essentially serves as the food for the cell’s processes (Whittingham, 375). Photosynthesis is the base for the nature of animal life and humankind. It does not solely power the life of the cell, but also the life of the earth because it is the…

    Photosynthesis and respiration are both processes that are necessary for the survival of organisms. However, in numerous ways these two processes are very diverse as they are responsible for distinct necessities. Therefore they both have similarities and differences. One major difference between the two is that photosynthesis takes place completely in plants while respiration occurs equally in plants and animals. Nevertheless to understand Photosynthesis and respiration, we need to understand what is photosynthesis and cellular respiration and examine each of these processes in detail and associate them to the parts of a cell responsible for each function.…

    Photosynthesis is the process by which plants create food for themselves which occurs in the cytoplast organ of the cell. They absorb carbon dioxide, water, and solar energy to produce glucose and oxygen (Doc C). Cellular respiration on the other hand, is the process occurring in the mitochondria by which organisms create energy to power cellular processes. This process takes in glucose and oxygen to create carbon dioxide, water, and energy in the form of ATP (Doc C). These processes follow the law of conservation of matter and energy as the amount of products is always equal to the amount of reactants in a chemical equation. So the amount of glucose and oxygen created during photosynthesis is equal to the amount of carbon dioxide and water used and the amount of carbon dioxide and water produced during cellular respiration is equal to the amount of glucose and oxygen used. Many people notice that the products of cellular respiration are the reactants of photosynthesis and the products of photosynthesis are the reactants of cellular respiration. This is because the two processes work together to provide organisms with food and…

    Photosynthesis is an anabolic process where plants produce sugars from carbon dioxide, light energy and water. The sugars are used for other anabolic reactions e.g. protein synthesis and the energy required for these reactions comes from ATP which is synthesised from chemical energy into ATP during respiration. The ATP used in plants is made from the conversion of light energy from the sun, to chemical energy by plants, into the form of organic molecules during respiration in all cells. The ATP produced can then be used by cells to perform useful work e.g.…

    Photosynthesis is a complex reaction, where plants (and some bacteria) release oxygen to change water and carbon dioxide to sugar for food. During photosynthesis plants and phytoplankton take carbon dioxide from the atmosphere by absorbing it into their cells. And by using energy from the sun, they combine carbon dioxide and water to form sugar (C6H12O6) and oxygen. This is shown through the chemical equation: 6CO2 + 6H2O  C6H12O6 + 6O2. The conversion of sunlight energy into chemical energy is associated with the green pigment chlorophyll (contained in the chloroplasts of a cell.) This is the compound that traps the sun’s light to start the process of photosynthesis. Glucose molecules are very simple sugars, and carbon atoms are locked up in them. The sugars are then converted into other molecules such as starch, fats, proteins, enzymes, and DNA. The sugar is…

    Respiration is the physical process by which living organisms take in oxygen from the surrounding medium and emit carbon dioxide. The term respiration is also used to refer to the liberation of energy, within the cell, from fuel molecules such as carbohydrates and fats. Carbon dioxide and water are the products of this process, which is sometimes called cellular respiration to distinguish it from the physical process of breathing. Cellular respiration is similar in most organisms, from one-celled organisms such as the amoeba and paramecium to higher animals.…
