The Stages of Cellular Respiration and Photosynthesis Essay

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).

In cellular respiration, glucose and oxygen are taken into the cells, then they are converted to carbon dioxide, water and ATP energy and some other energy. Some of the ATP energy is used in photosynthesis; a large amount of

Cellular respiration is the chemical process in which organic molecules, such as sugars, are broken down in the cell to produce utilizable energy in the form of ATP. ATP is the chemical used by all of the energy-consuming metabolic activities of the cell. In order to extract energy from these organic molecules, cellular respiration involves a network of metabolic pathways dedicated to this task.

In cellular respiration, the oxidation of glucose is carried out in a controlled series of reactions. At each step or reaction in the sequence, a small amount of the total energy is released. Some of this energy is lost as heat. The rest is converted to other forms that can be used by the cell to drive or fuel coupled endergonic reactions or to make ATP.

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

The first part of cellular respiration is glycolysis where energy is spent to break a glucose molecule down into two pyruvate molecules. A glucose molecule comes from your food and has 6 carbons on it. Glycolysis partially breaks

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

Every living thing needs cellular respiration to survive. Cellular respiration is the process that releases energy by breaking down glucose and other food molecules in the presence of oxygen. This process happens through three distinct operations which are glycolysis, the Krebs cycle, and the electron transport chain. Throughout these cycles, our bodies turn oxygen and glucose into carbon dioxide, water, and energy. Although this system seems simple enough, cellular respiration can not take place in just one step because all of the energy from glucose would be released at once, most of it being lost in the form of light and heat. All this plays a very important role in our lives and without it, organisms would cease to exist.

Cellular respiration is a process that happens in all living eukaryotic cells. What cellular respiration does is turn food often carbohydrates into energy for our bodies. Cellular respiration starts with a carbohydrates sugar called glucose. What it does is alter and break down the six carbon molecule glucose and altering it creating two three carbon molecules called pyruvic acids in an anaerobic process called glycolosis (Cellular respiration). What this process does is create two ATP molecules which are basically molecules which provide energy to run all cellular processes in our bodies (king). However, from here in the process can turn aerobic, meaning using oxygen if present or anaerobic meaning when oxygen is not present in a

Photosynthesis can be defined as the process that living organisms such as plants use to translate the sun’s energy into chemical energy. Once the plant has translated the sun’s energy into chemical energy it then releases that energy and makes it readily available to other living things (Vermaas, 2007).

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.

These reactions working in respiration are called catabolic reactions, that break bigger molecules down into smaller molecules , letting energy release in the operation , as weak so called high energy components are substituted by stronger components in the produce. Respiration is mainly how a cell releases energy to start the cellular procedure. Cellular respiration is thought of as an exoergic redox reaction that puts off heat. The general reaction happens in a multitude of biochemical processes, most of these are redox responses their selves. Even though cellular respiration happens to be a combustion metathesis , it obviously does not appear as one during its process in a living cell because of its sluggish discharge of energy from the multitude of oxidisation.

All organisms on earth depend on photosynthesis, in which light energy is used to make sugar and other food molecules from carbon dioxide and water. For example, plants and other photo-synthesizers need only energy from sunlight, carbon dioxide from air, and water from the soil to make the sugar glucose. Photosynthesis is the most important chemical process on earth because it provides food for virtually all organisms, not only for photo-synthesizers but for the organisms that eat them. Plants can capture the energy of the sun by a chemical process called photosynthesis. This chemical reaction can be described by the following simple equation:

Plant Cells help us in many ways.Plant Cells provide oxygen for us to breath. They make oxygen for us from a process called photosynthesis. Then your cells perform cellular respiration to make ATP. Photosynthesis and Cellular respiration are connected through an important relationship. Their formulas are the exact opposite. Cellular respiration formula is C6H12O6 + 6O2 → 6CO2 + 6H2O and photosynthesis is 6CO2 + 6H2O → C6H12O6+ 6O2.Photosynthesis makes glucose which then is turned back into carbon dioxide.In photosynthesis water is being broken down and in cellular respiration water is being combined with hydrogen to form water. The released oxygen is for cellular respiration. We breath the oxygen and the oxygen goes through our blood and cells. Photosynthesis happens everyday. Photosynthesis starts with the sun. It needs light to happen in the chlorophyll. The light is absorbed by the cell and starts the photosynthesis process. They then produce glucose from carbon dioxide and water. The glucose can be converted into pyruvate which releases ATP. Photosynthesis takes place in the chlorophyll. Chlorophyll is this green pigment inside the plant cell. It is a complex molecule. There are several modifications among

     Photosynthesis has a two-stage performance before plants produce the two products they are known to produce. These stages are Photosystem I and II. Photosystem II is dependant on light reactions for energy which causes the electrons to be react and be transferred to Photosystem II. The electrons are transported through the Photosystem II electron transport system, however some energy is used to drive ATP synthesis. Meanwhile, light is being absorbed by the Photosystem I, which causes the electrons to react. This process sends the electrons to the Photosystem I transport system where some energy is released as electrons travel through the electron transport system and is captured as NADPH. When this process is completed oxygen is released from the plant and glucose has been
