The Putrefaction Of Carbohydrates

In contrast, there are four metabolic stages happened in cellular respiration, which are the glycolysis, the citric acid cycle, and the oxidative phosphorylation. Glycolysis occurs in the cytoplasm, in which catabolism is begun by breaking down glucose into two molecules of pyruvate. Two molecules of ATP are produced too. Some of they either enter the citric acid cycle (Krebs cycle) or the electron transport chain, or go into lactic acid cycle if there is not enough oxygen, which produces lactic acid. The citric acid cycle occurs in the mitochondrial matrix, which completes the breakdown of glucose by oxidizing a derivative of pyruvate into carbon dioxide. The citric acid cycle produced some more ATPs and other molecules called NADPH and FADPH. After this, electrons are passed to the electron transport chain through

This process does not require oxygen and is referred to as fermentation. This process partially breaks down carbohydrates and it obtains a small amount of energy, again in the form of ATP. Pyruvic acid has to be broken down in respiration when formed by breaking down of glucose molecules, this can't be done in the same way as in aerobic respiration. When anaerobic respiration is taking place carbon dioxide and ethanol is formed.

Respiration is a chemical process by which organic compounds release energy. There are two types of respiration reactions that cells use to provide themselves with energy: aerobic and anaerobic (fermentation). (Chemistry for Biologists: Respiration. 2015) Both processes are similar within the initial steps of the reaction- beginning with glycolysis. However, in fermentation instead of the pyruvic acid being converted to acetyl coenzyme A, it’s converted into both ethanol and carbon dioxide in yeast and some plants and lactic acid in animal cells. Another distinct difference between the two processes is that anaerobic respiration uses oxygen

One of the most significant reactions in Glycolysis is reaction one which involves the phosphorylation of glucose to form glucose-6-phosphate. Through the transfer of the hydrolysis of ATP, this supplies energy for the reaction and makes it essentially irreversible, having a negative free energy change, which allows for a spontaneous reaction in cells. Although the preparatory phase is energy consuming and uses up 2 ATP, the pay off phase synthesizes 4 molecules of ATP, with the transfer of 4e- via 2 hydride ions to 2 molecules of NAD+. Therefore, a net gain of 2 ATP is achieved through the glycolytic pathway alone. Following the glycolytic pathway, due to the absence of oxygen, as oxygen cannot be supplied fast enough to undergo aerobic respiration, the athlete will instead, undergo lactic acid fermentation. Lactic acid fermentation involves pyruvate that is formed from the glycolytic pathway to be reduced to lactate, with the aid of the enzyme, lactate dehydrogenase, while the coenzyme Nicotinamide Adenine Dinucleotide (NADH) is oxidised to NAD+. The product NAD+ then re-enters the glycolytic pathway in order to produce 2 ATP. This process of lactic acid fermentation produces 2 ATP for each cycle, and thus, rapidly supplies the body with a small amount of energy. However, with the buildup of lactic acid in the body, the athlete will eventually encounter the feeling of discomfort as this accumulation of lactate causes the body to

Cellular respiration is the series of metabolic process by which living cells produce energy through the oxidation of organic substances. Cellular respiration takes place in the mitochondria. Fermentation is the process by which complex organic compounds such as glucose, are broken down by the action of enzymes into simpler compounds without the use of oxygen. The significance of these pathways for organisms is to allow for an organism to be able to generate ATP. Some organism that undergo cellular respiration are bacteria and fungi. Some organism that undergo fermentation are yeast and muscle cells. In cellular respiration, glucose is oxidized and releases energy. In cellular respiration, glucose produces ATP and 3-carbon molecules of pyruvate. The pyruvate is then further broken down in the mitochondria where it becomes oxidized and releases CO2 (Upadhyaya 2014). In the fermentation process oxygen does not play a part. This process converts glucose into pyruvate and produces ATP. From there pyruvate breaks down into CO2 and acetaldehyde (Upadhyaya 2014) Monosaccharides are known as simple sugars and their main function is being the source of energy for organisms. Disaccharides are two monosaccharides joined by a covalent bond and their primary function is to provide food to monosaccharides. Some disaccharides

A). The anaerobic metabolism of glucose to pyruvate is called glycolysis. This sequence of reactions will generate two molecules of pyruvate for every one molecule of glucose. This metabolism is anaerobic, which means that it does not require oxygen to be completed. The first phase of the process of glycolysis is called the preparatory phase. The entire process of glycolysis is started once glucose is trapped inside

Also, large substances such as, proteins are broken down by enzymes called proteases into amino acids, which is used and stored as energy. An example of this is; when the body gets exhausted the fuel which is converted from the protein is used as energy and also to repair worn out tissues to keep the body healthy and energised. It also stimulates the immune system and aids the body in ATP production.

2) What two chemicals are given out when carbohydrates are burned? If carbohydrates (made of carbon, hydrogen, and oxygen)

In this process, organic molecules, particularly sugars, are broken down to produce carbon dioxide and water, and energy is released.

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.

Uniquely, glycolysis is both anaerobic and aerobic. The end product pyruvate, from glycolysis, is anabolized to lactic acid when there is a need for energy without an adequate supply of oxygen available. This last step or reaction enables glycolysis to continue producing ATP without the need for oxygen, which is why it is called the anaerobic energy system (Fink, 2009).

These can include carbon dioxide and water as well as the breakdown from proteins which

There are four types of biomolecules, carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates are large chains of sugar found in food and living tissues. This includes sugars, starch, and cellulose. They have the same ratio of hydrogen and oxygen that water has, 2:1. They are broken down to release energy in the animal body. Lipids are any organic compounds that are fatty acids and don’t dissolve in water but do in organic solvents. Fatty acids can be found in natural oils, waxes, and steroids. Proteins are macromolecules that do everything in the cell. They are tools and machines that make things happen. Nucleic acids are long strands of nucleotides, and function primarily in storage and transmission of genetic information. There are two types of nucleic acids, DNA and RNA. DNA is the genetic material of all cellular organisms, and RNA sends out messages from the information that is held in the DNA.

The first part of the breakdown of glucose is known as Glycolysis, in which one molecule of glucose is broken down to two molecules of pyruvate (C3H4O3). The second part is the fermentation process in which the two pyruvate molecules are converted to two molecules of ethanol and two molecules of carbon dioxide.

Carbohydrates are the product that made up from carbon, hydrogen and oxygen. Carbohydrates are form by the combination of carbon dioxide and water molecules. The carbohydrates contain two specific functional group in it which is the hydroxyl groups and carbonyl groups.A reducing sugar is a type of sugar with is an aldehyde group.This means that sugar can act as a reducing agent.The procces of reducing sugar is isomerisation,example of reducing sugar islactose,maltose,glucose and fructose.All monosaccharides are capable of reducing other chemicals such as copper (II) sulphate to copper oxide.Beside that disaccharides such as maltose and lactose are reducing sugar,however sucrose is non reducing
