Cellular Respiration Lab Report

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

The last step of cellular respiration is the Electron transport chain (ETC). The ETC takes place in the inner mitochondrial membrane. Electrons from Hydrogen are carried by NADH and passed down an electron transport chain to result in the production of ATP. Results are the production of ~32 ATPs for every glucose. Oxygen, which is the final electron receptor, finishes the process by creating a water molecule and combining the remaining hydrogen molecules. Oxygen is the final electron receptor. Without it, the process cannot be complete (Cellular Respiration, 2004). The waste products of cellular respiration are CO2 and H2O that are the same incrediants used in photosynthesis. Plants store chemical energy by photosynthese and then harvest this energy via cellular respiration.

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.

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.

The overall goal being completed by cellular respiration is the building and the making of ATP. An important step in the cellular respiration process is known as Oxidation Phosphorylation, which occurs in the Mitochondria, or the power house of the cell. Glucose that is absorbed into the cells is used in this process. The energy from glucose is taken and energized and moved into an electron transport chain to be transported down the chain and release energy. This energy released is then captured and is used to pump what is known as H+ across the membrane of the cell, which powers ATP Synthase, forming ADP into the ATP energy source. Chemiosmosis takes place during Oxidation Phosphorylation, which uses the energy of the hydrogen ions to synthesize ADP into ATP.

Like Photosynthesis, cellular respiration is also a redox reaction where glucose loses electrons and hydrogen atoms to produce carbon dioxide causing the glucose to become oxidized. At the same time, oxygen gains electrons and hydrogen atoms, reducing it to water.

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.

Redox reactions interact with and contribute to the achievement of each of these goals. For instance, the first goal is to break down the glucose into six carbon dioxide molecules. One of the stages in which this goal is accomplished is in pyruvate oxidation, which begins with a redox reaction. NAD+ is reduced to NADH by taking an electron from pyruvate, which becomes oxidized; hence the term “pyruvate oxidation”. Pyruvate can then split, releasing carbon dioxide.

Cellular respiration and photosynthesis are the two most salient cycles that recreate and sustain the energy and life in our biosphere. Though interdependent, and similar in many ways, the two systems possess contradicting aspects as well. For instance, cellular respiration is a catabolic reaction. It breaks apart glucose to make carbon dioxide and water, and in doing so, transforms the energy of glucose into ATP. Thus, the primary source of energy for cellular respiration is glucose. This reaction contradicts with photosynthesis. Photosynthesis is an anabolic reaction that relies on carbon dioxide and water to form glucose and other byproducts. It also uses sunlight as a means of its most prominent energy source.

Oxidation can be defined as a gain in oxygen or loss of hydrogen, loss in electrons, and therefore loss of potential energy. Reduction is gain of hydrogen, or gain in electrons, and gain of potential energy. The organic food molecules are OXIDIZED to CO2. This is the process of glycolysis and making energy. The carbon molecules gain oxygen and are oxidized, and release all that energy to generate ATP. NADH is the REDUCED from of NAD+, because of the gain in hydrogen, or gain in electrons.

All living organisms need the energy to perform the basic life functions. Cells use a process called cellular respiration to obtain the energy needed. In cellular respiration, cells convert energy molecules like starch or glucose into a cellular energy called Adenosine triphosphate(ATP). There are two types of cellular respiration which include: Aerobic and Anaerobic respiration. In aerobic respiration, cells will break down glucose to release a maximum amount of ATP this takes place in the presence of oxygen. Aerobic also produces carbon dioxide and water as waste products and it takes place in the mitochondria. on the other hand, anaerobic respiration, a metabolic process, also produces energy and uses glucose, but it releases less energy and does not require the

    Cellular respiration is the group metabolic reactions that happen in the cell of living organism that creates adenosine triphosphate, ATP, from biochemical energy. The formula for cellular respiration is C6H12O6 +6O26CO2+6H2O+ATP.  This formula means glucose and oxygen are turned into water,carbon dioxide and adenosine triphosphate (ATP) energy through chemical reactions. Cellular respiration occurs in all cells which allows them to grow. Raphanus raphanistrum subsp. Sativus seed, also known as radish seed, undergo cellular respiration because they are not yet able to perform photosynthesis, which is how plants create their energy. Hymenoptera formicidae,commonly known as ants, undergo cellular respiration to produce the energy they need to live.
