What are the difference between aerobic and anaerobic respiration name some organisms that use the anaerobic mode of respiration

Aerobic denotes the term ‘in the presence of oxygen’ while the word anaerobic denotes the ‘absence of oxygen’. So the respiration which occurs in the presence of oxygen is called as aerobic respiration, on the other hand, respiration occurring in the absence of oxygen is known anaerobic respiration. So accordingly the chemical reaction involving the breakdown of the nutrient molecule with the aim of producing energy is called respiration. Thus the energy required by the body to perform well which is produced by the chemical reaction. This process takes place in the mitochondria or in the cytoplasm of the cell either aerobically or anaerobically. Below we will consider the important points which distinguish the aerobic respiration to that of anaerobic respiration.

VOICEOVER: Understanding respiration. Do not confuse respiration with breathing or to use the scientific name, ventilation. Respiration is a chemical reaction. It occurs in all plant and animal cells. During this reaction, energy from glucose is released. This energy enables organisms to live. Aerobic respiration requires oxygen. Carbon dioxide is produced as a by-product and we show this using the word equation: glucose plus oxygen, produces carbon dioxide and water. Aerobic respiration produces energy, much more efficiently than anaerobic respiration, but is a slower process. Anaerobic respiration does not require oxygen. Lactic acid is produced as a by-product. We show this using the word equation: glucose produces lactic acid. Anaerobic respiration produces much less energy than aerobic respiration, but it is a much faster process. Katie: OK, so, let's expand on what we've just heard, shall we? Dr. Tim: Alright, Katie. So what we've already learned is that respiration is not the same as breathing - it's a chemical reaction and it occurs in all living cells, all of the time, and his energy that's released from glucose. Now, there are two types of respiration. Over to you, Katie. Katie: OK. It's aerobic and anaerobic, but what's the difference between them? Dr. Tim: Perfect. So if we look at these two types of respiration as an equation, it'll help us to understand better. Aerobic respiration occurs in the presence of lots of oxygen, like if we were running a marathon or...

Definition Aerobic respiration is the process by which organisms use oxygen to turn fuel, such as fats and sugars, into chemical energy. In contrast, anaerobic respiration does not use oxygen. Respiration is used by all cells to turn fuel into energy that can be used to power cellular processes. The product of respiration is a molecule called adenosine triphosphate (ATP), which uses the energy stored in its phosphate bonds to power chemical reactions. It is often referred to as the “currency” of the cell. Aerobic respiration is much more efficient, and produces ATP much more quickly, than anaerobic respiration. This is because oxygen is an excellent electron acceptor for the chemical reactions involved in generating ATP. An overview of the stages of aerobic respiration Aerobic vs Anaerobic Similarities Both aerobic and anaerobic respiration are methods of generating energy. They also both start in the same way, with the process of glycolysis. “Glycolysis” literally means “sugar splitting,” and involves breaking a sugar molecule down into two smaller molecules. In the process of glycolysis, two ATP molecules are consumed and four are produced. This results in a net gain of two ATP molecules produced for every sugar molecule broken down through glycolysis. This is where the similarities between aerobic and anaerobic respiration end. In cells that have oxygen and aerobic respiration can proceed, a sugar molecule is broken down into two molecules of pyruvate. In cells that do ...

Answer: Aerobic respiration Anaerobic respiration 1. Aerobic respiration takes place in the presence of oxygen. 1. Anaerobic respiration takes place in the absence of oxygen. 2. The complete breakdown of food occurs in aerobic respiration. 2. Partial breakdown of food occurs in anaerobic respiration 3. The end products of aerobic respiration are carbon dioxide and water. 3. The end products in anaerobic respiration may be ethanol and carbon dioxide (as in yeast plants), lactic acid (as in animal muscles). 4. Glucose → carbon dioxide + water + energy respiration 4. Glucose → ethanol + carbon dioxide + energy Glucose → lactic acid + energy • Anaerobic respiration can take place in human cells during vigorous exercise and in yeast cells during fermentation. Q.

Aerobic and anaerobic respiration Aerobic respiration Respiration using oxygen to break down food molecules is called aerobic respiration . 'Aero' means air, which contains oxygen, leading to the name aerobic respiration. Glucose is the molecule normally used for respiration - it is the main respiratory substrate . Glucose is oxidised to release its energy, which is then stored in ATP molecules. The word equation for aerobic respiration is: glucose + oxygen → carbon dioxide + water (+ ATP made) You need to be able to recognise the chemical formulas: C 6 H 12 O 6 + 6O 2 → 6CO 2 + 6H 2 O Respiration is a series of chemical reactions, but this equation summarises the overall process. Aerobic respiration breaks down glucose and combines the broken down products with oxygen, making water and carbon dioxide. The carbon dioxide is a waste product of aerobic respiration because cells do not need it. The first stages of respiration occur in the cytoplasm of plant and animal cells, but most of the stages of respiration that release energy happen in the mitochondria . Microorganisms do not have mitochondria - they carry out respiration only in the cytoplasm . Anaerobic respiration Most organisms cannot respire without oxygen but some organisms and tissues can continue to respire if the oxygen runs out. In conditions of low or no oxygen the process of anaerobic respiration occurs. The 'an' in 'anaerobic' means without. During anaerobic respiration, the oxidation of glucose is incomple...

\( \newcommand\) • • • • • • Why oxygen? Oxygen is the final electron acceptor at the end of the electron transport chain of aerobic respiration. In the absence of oxygen, only a few ATP are produced from glucose. In the presence of oxygen, many more ATP are made. Aerobic vs. Anaerobic Respiration: A Comparison Aerobic respiration, which takes place in the presence of oxygen, evolved after oxygen was added to Earth’s atmosphere. This type of respiration is useful today because the atmosphere is now 21% oxygen. However, some anaerobic organisms that evolved before the atmosphere contained oxygen have survived to the present. Therefore, anaerobic respiration, which takes place without oxygen, must also have advantages. Advantages of Aerobic Respiration A major advantage of aerobic respiration is the amount of energy it releases. Without oxygen, organisms can split glucose into just two molecules of pyruvate. This releases only enough energy to make two ATP molecules. With oxygen, organisms can break down glucose all the way to carbon dioxide. This releases enough energy to produce up to 38 ATP molecules. Thus, aerobic respiration releases much more energy than anaerobic respiration. The amount of energy produced by aerobic respiration may explain why aerobic organisms came to dominate life on Earth. It may also explain how organisms were able to become multicellular and increase in size. Advantages of Anaerobic Respiration One advantage of anaerobic respiration is obvious. I...

In the scheme of things, you and I have a fairly limited range of ways to feed ourselves. We may get to decide between veggies and ice cream (and hopefully, end up enjoying both in healthy quantities!). However, it's not too likely that we're going to photosynthesize. We're also unlikely to eat hydrogen sulfide, the compound responsible for "rotten egg smell," for breakfast. We tend to be pretty familiar with photoautotrophs, such as plants, and chemoheterotrophs, such as humans and other animals. Prokaryote species fall into these two categories, as well as the two less familiar categories (photoheterotrophs and chemoautotrophs) to which plants and animals don't belong. 2 , 3 ^ 2 , 3 start superscript, 2, comma, 3, end superscript Prokaryotes that can't tolerate O 2 \text O_2 O 2 ​ start text, O, end text, start subscript, 2, end subscript and only perform anaerobic metabolism are called obligate anaerobes.

All cells do cellular respiration, and there are two main forms, aerobic cellular respiration and anaerobic cellular respiration. In eukaryotic cells cellular respiration occurs in the cytoplasm and the mitochondria. In prokaryotic organisms, such as bacteria, it occurs in the cytoplasm alone. What Is Aerobic Respiration? Aerobic cellular respiration is a type of cellular respiration that uses oxygen. Glucose and oxygen are the reactants and the products made are ATP, carbon dioxide and water. There are three main stages to aerobic cellular respiration: • Glycolysis • Krebs cycle (citric acid cycle) • Oxidative phosphorylation Glycolysis Glycolysis is common to both aerobic and anaerobic cellular respiration, whereas the Krebs cycle and oxidative phosphorylation are only part of aerobic cellular respiration. During glycolysis glucose, a simple sugar, is contained in the cell. It goes through a series of chemical reactions that produce two molecules of pyruvate and two molecules of ATP. ATP is cellular energy. G...
