Cellular Respiration Vs. Photosynthesis

Cellular Respiration is the physiological process of converting molecules into ATP. This process can occur in bacteria, protists, fungi, plants, and animals. It uses Oxygen (02) and Glucose (C6H1206) to transfer and transform electrons. Then it produces carbon dioxide (CO2) and Water (H2O). Thus, it is read as C6H12O6 + 6O2 --> 6H2O + 6CO2 + 32ATP. Respiration is split into three steps Glycolysis, Citric Acid Cycle, and Electron Transfer Chain (ETC).

My game was focused on the topic of energy transfer. Specifically the energy transfer in photosynthesis reactions (light-dependent and light-independent) and in respiration reactions. First photosynthesis is the process by which plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. There are two parts to photosynthesis, light dependent reactions and light independent reactions or the calvin cycle. Light-dependent reactions require sunlight. In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and converted into stored chemical energy, in the form of NADPH and ATP. The light-dependent reactions take place in the thylakoid membranes in the granum, which is a stack of thylakoids, within the

Both photosynthesis and cellular respiration are the main pathways of energy transportation in organisms. However, the reactants and the products are exact opposites in photosynthesis and in cellular respiration.

The Cellular respiration and photosynthesis form a critical cycle of energy and matter that supports the continued existence of life on earth. Describe the stages of cellular respiration and photosynthesis and their interaction and interdependence including raw materials, products, and amount of ATP or glucose produced during each phase. How is each linked to specific organelles within the eukaryotic cell? What has been the importance and significance of these processes and their cyclic interaction to the evolution and diversity of life?

Cellular respiration is bioenergetic process, meaning that it is governed by enzyme activity. Referring to what was previously learned about enzymes, it is known that enzyme-substrate reactions can

Cellular respiration is a very important process that occurs in all living organisms. In this process, chemical energy is obtained by the organisms’ food source to be turned into ATP or adenosine triphosphate, a form of energy that is easily utilized by the organisms’ bodies to carry out certain bodily functions (Largen, 2008, p.41). The chemical formula for cellular respiration is C6H12O6+6O2+6H2O→6CO2+12H2O+energy. This simply means that, with the use of glucose, six molecules of oxygen, and six molecules of water, an output of six carbon dioxide molecules, twelve molecules of water, and energy (ATP) is produced (Khan, 2010). Glucose is especially important in this process, given that it acts as a fuel in cellular respiration. (Cellular Respiration: Introduction, n.d.). In the biosphere, there is also a vast

Photosynthesis is the process of producing glucose, as for Cellular respiration is the process of breaking that glucose down in order to produce and release the energy stored in photosynthesis. Both of these processes create ATP (energy), photosynthesis and cellular respiration both function as a circle – the first using CO2 and releasing O2, while the other uses O2 and releases CO2. Another reason that both processes are complementary is because they entail the same components of H2O, energy, CO2, O2 and glucose, but the reactions are opposite to each other as explained above. (Mader, 2009)

First glucose is broken down in the process called glycolysis, then the pyruvate molecules are moved to the mitochondria, when this is happening the pyruvate molecules are converted into 2-carbon molecules these molecules then enter the Kreb Cycle. Moving on the energy created will now enter the electron transport chain, this energy will then produce ATP. The reactants are glucose and oxygen and the products are ATP, water, and carbon dioxide. During the Cellular Respiration glucose is being oxidized, along with carbon. On the other hand Oxygen, NAD+ and FADH are being reduced in Cellular Respiration.

Also, unlike photosynthesis, cellular respiration is known as a decomposition reaction. During this reaction, the exergonic release of energy is produced by breaking glucose down into smaller ATP molecules, water and carbon dioxide which is released into the air, for use by plants, every time we exhale

The purpose to cellular respiration and photosynthesis are to provide energy to both animal and plant cells. In photosynthesis, chloroplasts use carbon dioxide and light and produce glucose and oxygen, while in cellular respiration, the animal cell uses glucose and oxygen to produce carbon dioxide, water, and energy; which is the opposite of what chloroplasts do. The location of cellular respiration differ, the materials and products of each are opposites of one another, the different phases of that photosynthesis and cellular respiration have, and many other varieties of differences exist between plant and animal cells in cellular respiration and photosynthesis.

Glycolysis is followed by the Krebs cycle, however, this stage does require oxygen and takes place in the mitochondria. During the Krebs cycle, pyuvic acid is broken down into carbon dioxide in a series of energy-extracting reactions. This begins when pyruvic acid produced by glycolysis enters the mitochondria. As the cycle continues, citric acid is broken down into a 4-carbon molecule and more carbon dioxide is released. Then, high-energy electrons are passed to electron carriers and taken to the electron transport chain. All this produces 2 ATP, 6 NADH, 2 FADH, and 4 CO2 molecules.

Photosynthesis and respiration are both metabolic pathway reactions that are vital for the existence and survival of organisms in plants and animals. These reactions, both having the same goal, use the sun to produce free energy – ATP, which enables them to grow. The process’ used in photosynthesis and respiration have similarities and differences which complement each other in the environment to allow function, thus enabling them to each carry out the correct actions to fulfill their own necessities.

Photosynthesis and cellular respiration are two processes that go on in living things. Photosynthesis is a process used by plants and other autotrophs to capture light energy and use it to power chemical reactions that convert carbon dioxide and water into oxygen and energy rich carbohydrates. Cellular respiration is a process that releases energy by breaking down glucose and other food molecules in the presence of oxygen. This essay will compare and contrast these two functions

Both, Photosynthesis and Cell Respiration can occur in prokaryotic and eukaryotic cells, they are reactions essential for proving energy to all living things. They both used the same molecules and compounds during their processes. As process produces glucose (photosynthesis), the other breaks down the glucose to create ATP or energy that is used in cells. Photosynthesis is the process in which a plant undergoes to make its own food, this process occurs in the chloroplast of the plant cell.

Cellular respiration is a procedure that most living life forms experience to make and get chemical energy in the form of adenosine triphosphate (ATP). The energy is synthesized in three separate phases of cellular respiration: glycolysis, citrus extract cycle, and the electron transport chain. Glycolysis and the citric acid cycle are both anaerobic pathways because they do not bother with oxygen to form energy. The electron transport chain however, is aerobic due to its use of oxidative phosphorylation. Oxidative phosphorylation is the procedure in which ATP particles are created with the help of oxygen atoms (Campbell, 2009, p. 93). During which, organic food molecules are oxidized to synthesize ATP used to drive the metabolic reactions necessary to maintain the organism’s physical integrity and to support all its activities (Campbell, 2009, pp. 102-103).
