From my reading I learned that cellular respiration is a multi-step metabolic reaction type process that takes place in each living organism 's cell rather it be plant or animal. It’s my understanding that there are two types of cellular respiration, one called aerobic cellular respiration which required oxygen and anaerobic cellular respiration that does not require oxygen. In the anaerobic cellular respiration process, unlike the aerobic process oxygen is not required nor is it the last electron acceptor there by producing fewer ATP molecules and releasing byproducts of alcohol or lactic acid. The anaerobic cellular respiration process starts out exactly the same as anaerobic respiration, but stops part way through due to oxygen not being available in the cell in order to complete the process. The lactic acid is a fermentation type process that takes place in humans in the event there is oxygen in storage while alcoholic fermentation does not take place in humans, however it’s the same mitochondria process that takes place in yeast with a byproduct of ethyl alcohol instead.
Aerobic cellular respiration takes place in eukaryotic cells as well as prokaryotic cells. The anaerobic cellular respiration or fermentation process produces less ATP than in aerobic respiration and produces a toxic byproduct of lactate which becomes lactic acid or alcohol.
As Regina Bailey states in her photosynthesis article, (2015), Photosynthesis and cellular respiration are the two main processes performed by most living organisms to obtain usable energy from nature. While photosynthesis is performed by most plants who can prepare their own food, most animals fulfill their energy requirements through cellular respiration.

...electron charge, thereby attracting more electrons and molecules together as the electrons travel through the electron transport chain until finally the last complex in the electron transport chain passes the electrons to molecular oxygen (O2) to make water, in the case of aerobic respiration.
Even though photosynthesis is essentially the same as cellular respiration but only in reverse as a two stage process light cycle and dark cycle which takes place in the cytoplasm and mitochondria in cells. Photosynthesis is a light dependent reaction requiring light protons and a catalyst of chlorophyll that produces glucose and starch from inorganic carbon or carbon dioxide which accurse in plants, some bacteria and algae. The following equation summarizes the chemical changes that occur in photosynthesis when light is available. 6CO2 + 12H2O + light > C6H12O6 + 6O2 + 6H2O

Essay on Cellular Respiration : A Common Phenomenon During Exercise

- Cellular respiration is an important function for the body to obtain energy (Citovsky, Lecture 18). There are two types of cellular respiration; aerobic conditions and anaerobic conditions. Aerobic conditions are the cellular respiration occurred with oxygen while anaerobic conditions are cellular respiration occurred without oxygen. The most common cellular respiration is aerobic conditions where oxygen were supplied for phosphorylation (Campbell et al., pg 177). In human body, anaerobic conditions occurred when muscle cells are overworked and oxygen is depleted before it could be replenished (Citovsky, Lecture 19)....   [tags: Cellular respiration, Metabolism]

Photosynthesis And Aerobic Respiration Are Both Cellular Processes Essay

- Photosynthesis and aerobic respiration are both cellular processes that happen in order to create energy for the organism they’re taking place in. All forms of life need energy in order to work properly, but not all forms of life get this energy the same way. For more complex organisms, such as animals and fungi, this energy is obtained in the food they consume. Aerobic cellular respiration Reactants: C6H12O6+O2 Products: CO2+H2O+ATP Aerobic respiration takes place when sugar is oxidized in the presence of oxygen in a series of reactions that make the sugar molecules smaller and smaller....   [tags: Cellular respiration, Adenosine triphosphate]

Chemotrophic Respiration and Photosynthesis Essay

- Cellular respiration is the ability of a cell in an organism to metabolize chemicals in the production of adenosine triphosphate (ATP), the main energy molecule of the cell. There are two forms of cellular respiration. Chemotrophic respiration, which is used by animals and phototrophic respiration (a.k.a. photosynthesis) used by plants and fungi. Chemotrophic respiration requires oxygen to efficiently make ATP and gives off carbon dioxide as a waste product. Photosynthesis requires carbon dioxide and gives off oxygen as a waste product....   [tags: chemical metabolization, cellular respiration]

The Degradation Of Glucose Throughout The Two Different Forms Of Respiration

- Task 1 There are our series in the degradation of glucose in the two different forms of respiration. This includes glycolysis, link reaction, Krebs cycle and the electron transport chain. The degradation of one molecule of glucose in the presence of oxygen goes through all four series. Inside aerobic respiration, the pyruvate moves to the mitochondria, whereas in the anaerobic respiration, the pyruvate stays in the cytoplasm. This is therefore showing that anaerobic respiration goes through all four series, whereas aerobic respiration only goes through the first stage, which is glycolysis....   [tags: Cellular respiration, Adenosine triphosphate]

Essay on Ethanol Reduces Cellular Energy Supply By Altering The Metabolism

- Ethanol reduces cellular energy supply by altering the metabolism in mitochondria. While there are two other pathways in which ethanol can be metabolized, I introduce the mitochondria because it is responsible for synthesizing the ATP needed by our cells. The oxidation reaction that occurs in response to the presence of cellular ethanol causes an increase in the production of nicotinamide adenine dinucleotide hydrate (NADH) via the electron transport chain in the inner mitochondrial membrane. Metabolism of ethanol bypasses the metabolic control of the Krebs cycle dehydrogenases which regulate the amount of NADH produced by the electron transport system....   [tags: Metabolism, Cellular respiration]

Glycolysis : An Essential Anaerobic Pathway For Atp Production Essay

- 1. Glycolysis is an essential anaerobic pathway for ATP production in the body. There are various steps and processes that occur and lead to the production of various products and most importantly ATP. Let’s dive right into it and get started on the process of glycolysis. Glycolysis occurs in the cytosol of the cell and can be divided into three different phases, which include sugar activation, sugar cleavage, and lastly sugar oxidation and ATP formation. The first steps in glycolysis require ATP to get started, this can be thought of as the investment phase of glycolysis....   [tags: Cellular respiration, Adenosine triphosphate]

Adenosine Triphosphate ( Atp ) Essay

- Since adenosine triphosphate (ATP) was discovered in 1929 by Karl Lohmann (Khakh and Burnstock, 2009) its known significance as a molecule has grown and its importance as a universal energy storing molecule is now abundantly clear. ATP is a ubiquitous molecule broken down by cells to produce chemical energy needed for efficient function. It is by far the most widely used energy storing molecule spanning across all cells and body systems of all known living organisms (Lu et al. 2014). ATP contains an adenosine base, a ribose sugar and three phosphate groups and its structure is shown in figure 1....   [tags: Adenosine triphosphate, Cellular respiration]

Essay about Respiration and Glycolysis

- Respiration can be defined as the oxidation of the end products of glycolysis with the storage of the energy in the form of ATP. Cellular respiration occurs when oxygen is available, and the products are carbon dioxide and water. There are three main pathways in the cellular respiration process. These are: pyruvate oxidation, the citric acid cycle, and the respiratory chain. Pyruvate oxidation in eukaryotic cells occurs inside the mitochondrion in the inner membrane, and in prokaryotes on the inner face of the plasma membrane....   [tags: essays research papers]
