Cellular Respiration

Cellular respiration, or simply respiration, is defined as an adenosine triphosphate(ATP) generating process in which molecules are oxidized and the final electron acceptor is (almost always) an inorganic molecule (Tortora, Funke & Case, 2013). The movement of an electron transport chains plays a very vital role in respiration. Respiration is classified in two categories.’ The first category is if an organism requires oxygen for growth and survival; this category is called aerobe. The second category is for the organisms that do not use oxygen; this is also known as anaerobic (Medical Prep Institute Tampa Bay (2014). Aerobic organisms consist of most animals and some fungi. Oxygen is detrimental to anaerobic organisms because it can kill …show more content…
It takes place in the mitochondrial matrix and requires oxygen. The Kreb Cycle, also called the triacarboxylic acid (TCA) cycle or citric acid cycle, is a series of biochemical reactions in which the large amount of potential chemical energy stored in Acetyl coenzyme A (Acetyl CoA ) is released step by step. (Medical Prep Institute Tampa Bay (2014). In this cycle, a series of oxidations and reductions transfer that potential energy, in the form of electrons, to electron-carrier coenzymes; chiefly nicotinamide adenine dinucleotide (NAD+). (Tortora, Funke & Case, 2013). It will utilize the pyruvate molecules from Glycolysis to produce 2-adenosine triphosphate(ATP) plus more than a few molecules of FADH2 and Nicotinamide_adenine_dinucleotide hydrogen (NADH) for the electron transport chain. The pyruvic acid derivatives are oxidized; the coenzymes are reduced. Glucose and oxygen join together to develop carbon dioxide, water and adenosine triphosphate (ATP). Adenosine triphosphate(ATP) helps bring energy to the living cells so that they may function properly. The result of a chemical reaction is both carbon dioxide and water. Citric acid is the number one and last concoction of the Krebs cycle. Citric acid can and will distribute plus regenerates in the process of adenosine triphosphate(ATP) synthesis. The Kreb Cycle consists of numerous chemicals and enzymes that work hand in hand with each other. Acetyl coenzyme A (Acetyl CoA ) bonded together with oxaloacetate to create a citrate, or citric acid. However with this union citric acid loses carbon dioxide from the oxaloacetate while the process of oxidation occurs. After that, the electrons from a chemical reaction transfer to the coenzyme nicotinamide adenine dinucleotide (NAD+), which then brings on Nicotinamide_adenine_dinucleotide hydrogen (NADH). The Acetyl coenzyme A (Acetyl CoA ) molecule produces three molecules of
