Aerobic and anaerobic respiration

There are two suitable answers I can give for this question- 1) Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. This is the scientific which describes respiration. 2) If you're asking why, It's a natural process which god has made. There are few questions which science cannot explain. Choose the best answer :) Do tell me if I'm wrong. Actually the main reason by which alcohol affects the body physically is the it gets into the blood and as the blood gets filtered in the liver, every time alcohol passes through liver, some of the liver cells get killed. But this happens when you drink lots of alcohol for a long time. The amount of alcohol is negligible as most of it is evaporated when it is being baked. - [Instructor] Have you wondered why you need to breath oxygen to stay alive? How does oxygen help our bodies? And what's the connection of this oxygen with the pain that you get sometimes when you are lifting weights or when you're running, the cramps that we get? How are these things connected? The answer lies in cellular respiration. So what is this? Let me start with what it is not. Respiration reminds me of breathing. But let me tell you, respiration is not breathing, okay? Even though in our daily terms, we might associate respiration with breathing but in biology, they're two different things. So what exactly is respiration then? Well, respiration is a process in which the cells of your body,...

Glycolysis is a series of reactions that extract energy from glucose by splitting it into two three-carbon molecules called pyruvates. Glycolysis is an ancient metabolic pathway, meaning that it evolved long ago, and it is found in the great majority of organisms alive today 2 , 3 ^ 2 , 3 start superscript, 2, comma, 3, end superscript . Glycolysis has ten steps, and depending on your interests—and the classes you’re taking—you may want to know the details of all of them. However, you may also be looking for a greatest hits version of glycolysis, something that highlights the key steps and principles without tracing the fate of every single atom. Let’s start with a simplified version of the pathway that does just that. • Energy-requiring phase. In this phase, the starting molecule of glucose gets rearranged, and two phosphate groups are attached to it. The phosphate groups make the modified sugar—now called fructose-1,6-bisphosphate—unstable, allowing it to split in half and form two phosphate-bearing three-carbon sugars. Because the phosphates used in these steps come from ATP \text ATP start text, A, T, P, end text molecules get used up. Energy investment phase. Glucose is first converted to fructose-1,6-bisphosphate in a series of steps that use up two ATP. Then, unstable fructose-1,6-bisphosphate splits in two, forming two three-carbon molecules called DHAP and glyceraldehyde-3-phosphae. Glyceraldehyde-3-phosphate can continue with the next steps of the pathway, and DH...

Organisms such as prokaryotes and eukaryotes use respiration mechanisms for the breakdown of food that may require environmental oxygen. The process by which mitochondria use to transfer the energy in foods to ATP is known as cellular respiration. In this process, food molecule breaks down in mitochondria, may consume oxygen, and transfer energy to cells (in which, it is stored as ATP molecule) and the There are two types of cellular respiration- they are aerobic respiration and anaerobic respiration. The cells of animals, plants, and many bacteria need oxygen (O 2 ) to facilitate energy transfer during cellular respiration. In these organisms, the type of cellular respiration that takes place is called aerobic respiration. The meaning of the word aerobic is with air. On the other hand, in the case of anaerobic respiration, the organisms do not require oxygen (O 2 ) for cellular respiration. Alcohol fermentation, lactic acid fermentation, etc. are examples of anaerobic respiration. Cellular respiration is different from normal respiration. Respiration is more commonly referred to as breathing and it is a physical act of inhaling and exhaling process. While cellular respiration is the process that occurs inside cells and involves the use of oxygen to transfer energy from food to ATP. Some organisms are capable of respiration anaerobically (in the absence of oxygen). In the absence of oxygen, these organisms manage to accept the electrons by using inorganic molecules. For ex...

Aerobic Respiration Respiration is one of the important chemical processes, which is carried out by all living organisms including plants animals and humans in order to release energy required for life processes. The process of respiration occurs both during the presence or in the absence of Oxygen For instance, human beings undergo the process of respiration by inhaling oxygen gas and exhaling carbon dioxide gas. Many other living organisms including plants and animals undergo respiration process to obtain energy for their metabolic activities. Table of Contents • • • • • Respiration is of two types, aerobic respiration, and anaerobic respiration. Aerobic Respiration: It is the process of Anaerobic Respiration: It is a process which takes place in the absence of oxygen gas. In this process, the energy is obtained by the breakdown of glucose in the absence of oxygen. One of the best examples of anaerobic respiration is the process of fermentation in yeast. Let us learn in detail about the aerobic respiration, its diagram and its process. Also refer: What is Aerobic Respiration? Aerobic respiration is a biological process in which food glucose is converted into energy in the presence of oxygen. The chemical equation of aerobic respiration is as given below- Glucose (C 6H 12O 6) + Oxygen 6(O 2) → Carbon-dioxide 6(CO 2) + Water 6 (H 2O) + Energy (ATP) According to the above-given chemical equation, energy is released by splitting the glucose molecules with the he...

Cellular respiration is the process by which cells derive energy from glucose. The chemical reaction for cellular respiration involves glucose and oxygen as inputs, and produces carbon dioxide, water, and energy (ATP) as outputs. There are three stages to cellular respiration: glycolysis, the Krebs cycle, and the electron transport chain. Created by Sal Khan. Pretty much. Plant cells do cellular respiration, too. The difference is that plants (and photosynthetic bacteria) don't need to eat something to get the energy. They have an extra process by which they produce their own glucose, using energy from the sun. The reaction, somewhat simplified, is 6 CO2 (carbon dioxide) + 12 H2O (water) + light ---> C6H12O6 (glucose) + 6 H2O (water) + 6 O2 (oxygen). Then, cellular respiration, which is the same in plants and in animals, takes that glucose, breaks it back up, and harvests energy from it in the form of ATP. well the total ATPs produced in aerobic repiration should be 38... However, muscle cells & neurons produce only 36 molecules of ATP per glucose molecule. Its because the 2 molecules of NADH produced during glycolysis in muscle cells & neurons dont enter the ETC directly but through other carriers, which transfer the electrons and H+ to the cytochromes. Therefore, these two NADH molecules produce 2 molecules of ATP only, instead of the usual 3... Your question about how much ATP we make each second is an interesting one! Here's what I've found out. An adult woman needs to...

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...
