What important molecule is regenerated in fermentation and respiration?
Both of these processes make ATP which are required by cells as a source of energy. Fermentation is very inefficient at producing ATP compared to aerobic respiration, but ATP is still produced, nonetheless.
Why fermentation gives less energy compare to aerobic respiration?
Fermentation releases less energy than respiration because it does not completely oxidize glucose. Fermentation does not utilize the Kreb Cycle or the electron transport system, leaving it with a gain of just 2 ATP from substrate level phosphorylation.
What is the difference in energy production between anaerobic and aerobic respiration?
Respiration is one of the imperative functions of the body that are of crucial importance for all the living organisms be it human being, or the microscopic bacteria. In general the process of respiration serves two basic purposes in living organisms, the first one being disposal of electrons generated during catabolism and the second one being production of ATP. The respiration machinery is located in cell membranes of prokaryotes whereas it is placed in the inner membranes of mitochondria for eukaryotes. Respiration requires a terminal electron acceptor. Simply put, the respiration process, which uses oxygen as its terminal electron acceptor, is called aerobic respiration and the one, which uses terminal electron acceptors other than oxygen, is called anaerobic respiration.Differences between Aerobic and Anaerobic RespirationStarting from the bio-chemical pathway used to utilize bio-molecules, to the amount of energy produced in the respiration process, there exist a lot of differences between aerobic and anaerobic respiration. Let us discuss the two respiration processes separately with respect to the process, outcome and the chemical reactions involved in aerobic and anaerobic respiration.Aerobic RespirationAerobic respiration is the process that takes place in presence of oxygen. Aerobic respiration is the metabolic process that involves break down of fuel molecules to obtain bio-chemical energy and has oxygen as the terminal electron acceptor. Fuel molecules commonly used by cells in aerobic respiration are glucose, amino acids and fatty acids.. The process of obtaining energy in aerobic respiration can be represented in the following equation:Glucose + Oxygen →Energy + Carbon dioxide + WaterThe aerobic respiration is a high energy yielding process. During the process of aerobic respiration as many as 38 molecules of ATP are produced for every molecule of glucose that is utilized. Thus aerobic respiration process breaks down a single glucose molecule to yield 38 units of the energy storing ATP molecules.Anaerobic respirationThe term anaerobic means without air and hence anaerobic respiration refers to the special type of respiration, which takes place without oxygen. Anaerobic respiration is the process of oxidation of molecules in the absence of oxygen, which results in production of energy in the form of ATP or adenosine tri-phosphate. Anaerobic respiration is synonymous with fermentation especially when the glycolytic pathway of energy production is functional in a particular cell. The process of anaerobic respiration for production of energy can occur in either of the ways represented below:Glucose (Broken down to) →Energy (ATP) + Ethanol + Carbon dioxide (CO2)Glucose (Broken down to) →Energy (ATP) + Lactic acidThe process of anaerobic respiration is relatively less energy yielding as compared to the aerobic respiration process. During the alcoholic fermentation or the anaerobic respiration (represented in the first equation) two molecules of ATP (energy) are produced. for every molecule of glucose used in the reaction. Similarly for the lactate fermentation (represented in the second equation) 2 molecules of ATP are produced for every molecule of glucose used. Thus anaerobic respiration breaks down one glucose molecule to obtain two units of the energy storing ATP molecules.
What organisms does cellular respiration occur in?
Virtually all oxygen using organisms have cellular respiration going on. C.R. is the breakdown of glucose using oxygen to release energy as ATP - so anything - plants, animals, single celled organisms - that take in oxygen and glucose are going to do CR. Organisms that can't tolerate oxygen or run out of oxygen (like your muscles during a strenuous workout) will do fermentation instead. Fermentation will get the job done but respiration releases much more energy per molecule of glucose.
What is are mitochondria?
The mitochondria basically gives your body energy, its the "power house" of the cell it can be compared to a power plant in a town.
What important molecule is regenerated in fermentation and respiration?
Both of these processes make ATP which are required by cells as a source of energy. Fermentation is very inefficient at producing ATP compared to aerobic respiration, but ATP is still produced, nonetheless.
Does acetic acid production involves submerged fermentation?
yeh,but the quality of the acetic acid is not that well as compared to surface processes
What are disadvantages of fermentation when compared to the processes aerobic and anaerobic respiration?
The equation for anaerobic respiration is: glucose ---> lactic acid + carbon dioxide + energy To know the disadvantages of anaerobic respiration it is best to compare it to aerobic respiration which involves oxygen (glucose + oxygen ---> carbon dioxide + water + energy) For humans to respire regularly and for long periods of time, oxygen is required. This means that anaerobic respiration through humans causes a lack of oxygen, and cannot be carried out for a very long time. Lactic acid is also produce and this is toxic and causes things such as cramp to build up. Anaerobic respiration also produces very little energy compared to aerobic respiration so is not suitable for every day respiration! Humans will mostly breathe anaerobically in situations such as sprinting in a race.
What are the events that lead to fermentation in aerobic organisms?
Fermentation in aerobic organisms usually occurs when there is not enough oxygen available for cellular respiration. This can happen during vigorous exercise, when the demand for oxygen exceeds the amount that can be supplied to the muscles. As a result, muscle cells revert to fermentation to generate energy, producing lactic acid as a byproduct. This process allows the cells to continue generating ATP, albeit at a lower efficiency compared to aerobic respiration.
What is fermentation?
Fermentation is the process by which cells release energy (ATP) under anaerobic conditions . Several major products of fermentation are ethanol, lactic acid, and hydrogen gas. Fermentation of sugars by yeast is typically used as the source of ethanol for alcoholic beverages.During glycolysis it makes a net amount of 2 molecules of ATP (energy). Fermentation happens anaerobically (without oxygen) and the reduction of pyruvate into lactate itself does not yield any energy (ATP).The chemical breakdown of a substance, by bacteria,yeast, or other microorganisms typically involving effervescence and the giving off heat*The process of Fermentation involves the making of beer,wine,and liquor, in which sugars are converted to ethyl alcohol.*(archaic)agitation; excitement("I found Paris in high fermentation")
Why fermentation gives less energy compare to aerobic respiration?
Fermentation releases less energy than respiration because it does not completely oxidize glucose. Fermentation does not utilize the Kreb Cycle or the electron transport system, leaving it with a gain of just 2 ATP from substrate level phosphorylation.
When there is not enough oxygen for aerobic respiration what is that called?
During times of insufficient oxygen, the cell undergoes glycolysis, where 2 existing molecules of ATP can form 4 molecules and pyruvic acid. This is an insignificant amount compared to 38 molecules of ATP made by the cellular respiration, which is why it is important to always have enough oxygen.
What is the biggest disadvantage of making ATP by means of fermentation?
Anaerobic fermentation produces very little ATP compared to oxidative phosphorylation.
What is the ratio of terrazzo tile production?
A ratio is a comparison between two measures. Here there is only one: terrazzo tile production. Is the question meant to be production compared with demand? Production now compared with some time in the past (or future)? Production in one region compared with another? Production of terrazzo tiles compared with other tiles?
What is the chemiosmosis production of ATP compared to in photosynthesis?
The chemiosmotic production of ATP through photophosphorylation in photosynthesis is closely related to the chemiosmotic production of ATP through oxidative phosphorylation in cellular respiration. Both processes utilize a proton gradient across a membrane to power the ATP synthase which phosphorylates ADP into ATP.
