Aerobic Respiration
Anaerobic Respiration
Definition Aerobic respiration uses oxygen. Anaerobic respiration is respiration without oxygen; the process uses a respiratory electron transport chain but does not use oxygen as the electron acceptors.

The process of aerobic vs anaerobic respiration
The sugar molecules stored in the food are broken apart through enzyme-mediated reactions and the energy released is absorbed by cells. This process is much more effective in the presence of oxygen through aerobic respiration.
Aerobic respiration requires oxygen in order to generate energy (ATP). It is the preferred method of pyruvate breakdown from glycolysis and requires that pyruvate enter the mitochondrion in order to be fully oxidized by the Krebs cycle. The product of this process is energy in the form of ATP (Adenosine Triphosphate), by substrate-level phosphorylation, NADH and FADH2.
Anaerobic and aerobic respiration share the initial pathway of glycolysis but aerobic metabolism continues with the Krebs cycle and oxidative phosphorylation. The post glycolytic reactions take place in the mitochondria in eukaryotic cells, and in the cytoplasm in prokaryotic cells.
Fermentation in anaerobic respiration
Without oxygen, pyruvate is not metabolized by cellular respiration but undergoes a process of fermentation. The pyruvate is not transported into the mitochondrion, but remains in the cytoplasm, where it is converted to waste products that may be removed from the cell. This serves the purpose of oxidizing the hydrogen carriers so that they can perform glycolysis again and removing the excess pyruvate.
This waste product varies depending on the organism. In skeletal muscles, the waste product is lactic acid. This type of fermentation is called lactic acid fermentation. In yeast, the waste products are ethanol and carbon dioxide. This type of fermentation is known as alcoholic or ethanol fermentation. The ATP generated in this process is made by substrate phosphorylation, which is phosphorylation that does not involve oxygen.
Krebs cycle in aerobic respiration
The Krebs cycle (also known as the citric acid cycle, or the tricarboxylic acid cycle) is a series of enzyme-catalysed chemical reactions, which is of central importance in aerobic respiration. the citric acid cycle is part of a metabolic pathway involved in the chemical conversion of carbohydrates, fats and proteins into carbon dioxide and water to generate a form of usable energy. Other relevant reactions in the pathway include those in glycolysis and pyruvate oxidation before the citric acid cycle, and oxidative phosphorylation after it. Therefore, carbohydrates break into sugar and then into ATP. The overall process of aerobic respiration can be understood by the following reaction. C6H12O6 + 6O2 + 6H2O ——> 6CO2 + 12H2O + energy.
Energy efficiency of aerobic vs anaerobic respiration
Aerobic metabolism is 19 times more efficient than anaerobic metabolism (which yields 2 mol ATP per 1 mol glucose). Anaerobic respiration is less efficient at using the energy from glucose since 2 ATP are produced during anaerobic respiration per glucose, compared to the 38 ATP per glucose produced by aerobic respiration. This is because the waste products of anaerobic respiration still contain plenty of energy. Ethanol, for example, can be used in gasoline (petrol) solutions. Glycolytic ATP, however, is created more quickly.
For prokaryotes to continue a rapid growth rate when they are shifted from an aerobic environment to an anaerobic environment, they must increase the rate of the glycolytic reactions. Thus, during short bursts of strenuous activity, muscle cells use anaerobic respiration to supplement the ATP production from the slower aerobic respiration, so anaerobic respiration may be used by a cell even before the oxygen levels are depleted, as is the case in sports that do not require athletes to pace themselves, such as sprinting.

Cells in the body use ATP as a direct source of energy. The conversion of glucose into ATP takes place during respiration. There are 2 different types of respiration, the more common and frequent one is aerobic respiration which is the production of ATP for energy.

Cellular respiration includes the processes of glycolysis, krebs cycle, and the electron transport chain. Glycolysis is used to convert glucose to produce two pyruvate as well as 4 ATP’s and 2 NADH but uses 2 ATP to have a net product of 2 ATP and 2 NADH. The krebs cycle converts pyruvate to Acetyl CoA, which produces 2 ATP,8 NADH, and 2 FADH’s per glucose molecule. Electron transport Chain is the last and most important step of cellular respiration, it makes ATP with the movement of electrons from high energy to low energy that makes a proton gradient which makes ATP, this cannot occur unless oxygen is present. Fermentation is an anaerobic process in which converts sugars into acids, alcohol, or alcohol. This process occurs in yeast and bacteria as well as muscle cells that have no oxygen left. In yeast fermentation produces ethyl alcohol and carbon dioxide from glucose and fructose. Fermentation in bacteria cells the process of fermentation produces ethanol, while in human muscle cells fermentation produces lactic acid in cells that have a short…

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. Basically, cellular respiration is a metabolic process that releases energy from organic compounds (such as C6H12O6) by metabolic chemical oxidation in the mitochondria within each cell. Proteins, carbohydrates, and fats can all be broken down into fuel for the cell but cellular respiration is usually correlated with glucose. Cellular respiration also requires O2 to carry out its pathway, as oxygen will act as a final electron acceptor. So, the final equation that can be represented for Cellular Respiration is: C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + heat.…

Cellular respiration allows organisms to use (release) in the chemical bonds of glucose(C6H12O6). The energy in glucose is used to produce ATP. Cells use ATP to supply their energy needs. Cellular respiration is therefore a process in which the energy in glucose is transferred to ATP. In respiration, glucose is transferred to ATP. Oxidized and thus releases energy. Oxygen is reduced to form water.…

Fructose, a monosaccharide or simple sugar found in fruits, fruit juices and sweeteners such as honey and contains 6 carbons, is broken down by an enzymatic reaction. Fructose is a carbohydrate and is a good source of energy for the body, but it needs to be broken down by enzymes to become energy that can be used by the body. When fructose is consumed the first step begins with the enzyme fructokinase binding with the fructose which produces fructose-1-phosphate. The second step of the cycle takes place when the enzyme aldolase B splits the fructose-1-phosphate into 2 three carbon molecules - DHAP (dihydroxyacetone phosphate) and glyceraldehyde. At this point these two products can enter glycolysis and produce energy for the body to use.…

Cellular respiration is an ATP-producing catabolic process in which the electron receiver is an inorganic molecule. It is the release of energy from organic compounds by chemical oxidation in the mitochondria within each cell. Carbohydrates, proteins, and fats can all be metabolized, but cellular respiration usually involves glucose: C6H12O6 + 6O2 → 6CO2 + 6H2O + 686 Kcal of energy/mole of glucose oxidized. Cellular respiration involves glycolysis, the Krebs cycle, and the electron transport chain. Glycolysis is a catabolic pathway that occurs in the cytosol and partially oxidizes glucose into two pyruvate (3-C). The Krebs cycle occurs in the mitochondria and breaks down a pyruvate (Acetyl-CoA) into carbon dioxide. These two cycles both produce a small amount of ATP by substrate-level phosphorylation and NADH by transferring electrons from substrate to NAD+. The Krebs cycle also produces FADH2 by transferring electrons to FAD. The electron transport chain is located at the inner membrane of the mitochondria and accepts energized electrons from enzymes that are collected during glycolysis and the Krebs cycle, and…
