Whice process of cellular respiration produces the most ATP?
The electron transport chain produces the most ATP during cellular respiration. It is the final stage of aerobic respiration and occurs in the inner mitochondrial membrane. Here, electrons are passed down a series of protein complexes, generating a proton gradient that drives ATP synthesis.
Which stage of cellular respiration produces the most ATP?
The Electron Transport process is the third process in cell respiration, it requires oxygen directly. The electron transport "chain" is a series of electron carriers in the membrane of the mitochondria. Through a series of reactions, the "high energy" electrons are passed to oxygen. In the process, a gradient is formed, and ultimately ATP (Adinosine triphosphate), an energy molecule is formed.Therefore this stage produces the most ATP.
Which animal product is least efficient at converting feed consumed into the final product?
beef
What are the 3 steps of aerobic cellular respiration?
Aerobic respiration is the discharge of energy from glucose or another organic substrate in the presence of OxygenThe three stages of aerobic respiration are glycolysis, citric acid cycle, and oxidative phosphorylation.Glycolysis takes place inside the cytoplasm; the citric acid cycle takes place inside the mitochondria, and the oxidative phosphorylation takes places in the mitochondria.Cellular respiration is in three stages as follows:GLYCOLYSISTakes place in the cytoplasm of the cell and is common to both aerobic and anaerobic respiration.glycolysis means literally that glucose is split and the 6 carbon glucose molecule is broken down to 2 X 3carbon molecules of Pyruvic acid. This produces a net gain of 2 ATP molecules.If oxygen is absent (anaerobic) in animal cells, such as muscle, 3C Pyruvic acid is converted to lactic acid.In plant cells, such as yeast, pyruvic acid is converted to 2C Ethanol + CO2 (fermentation)In both of the above only 2 ATP molecules are produced per glucose molecule respired.If oxygen is present (aerobic), pyruvic acid enters the mitochondrion to the fluid matrix where Kreb's cycle stages occur.During Kreb's cycle Citric acid is initially formed and is then broken down in a series of enzyme controlled rections releasing CO2 (waste product) and hydrogen.Hydrogen is picked up by a hydrogen carrier molecule called NAD and transported to the hydrogen carrier sytem (Cytochrome sytem) on the cristae of the mitochondrion for the final stage of respiration.Cytochrome system- electron transport system:Hydrogen is passed along a chain of hydrogen carrier molecules by a series of oxidation and reduction reactions.each time a hydrogen molecule is passed along, a molecule of ATP is produced from ADP and phosphate.The final Hydrogen acceptor is oxygen and produces a molecule of water (the other waste product).In all, 36 ATP molecules are generated during the Cytochrome system, making a total of 38 ATP (36 from cytochrome system + 2 ATP from glycolysis) produced when Glucose is respired aerobically.This makes aerobic respiration 19X more efficient at producing ATP than anaerobic respiration.Hope this helps!
Why is oxygen needed to produce ATP?
Oxygen is NOT needed to produce ATP. This is only true for Oxidative Phosphorylation. Substrate Level Phosphorylation does not require ATP at all. While ATP can be produced without oxygen via a process called anaerobic respiration, aerobic respiration is a much more efficient means of ATP production. Aerobic respiration is the release of energy from glucose or another organic substrates in the presence of Oxygen. Strictly speaking aerobic means in air, but it is the Oxygen in the air which is necessary for aerobic respiration. Anaerobic respiration is in the absence of air. Aerobic respiration takes place in almost all living things. It is easy to get rid of the Carbon Dioxide and excess water; this is excretion (the removal of the toxic waste products of metabolism), and maximum energy is released from the glucose. Some organisms can respire in the absence of air: this is anaerobic respiration. This does not release so much energy and it produces much more toxic waste products. However, if Oxygen is not available, anaerobic respiration is better than nothing. When this happens in our muscles we produce lactic acid which gives you cramp.
Is ADP is the final energy product of aerobic cellular respiration?
No. That's ATP.
What is the final product of aerobic cellular respiration are?
36 ATPs are produced.CO2 and H2O also given out.
In cellular respiration the final electron acceptor is?
O2 ADDED: Not O2, but one atom of oxygen.
Because the final stages of cellular respiration require oxygen the are said to be what?
aerobic
What is the final waste product of cellular respiration?
CO2
What is the terminal electron acceptor in aerobic cellular respiration?
NAD+ is the first electron acceptor in cellular respiration (O2 is the final acceptor).
Where do the final steps in aerobic cellular respiration occur?
The final steps of aerobic cellular respiration occur in the mitochondria, specifically in the electron transport chain and oxidative phosphorylation. Here, most of the ATP is produced through the electron transport chain by using the energy carried by electrons from previous stages of respiration.
What type of cellular respiration occurs with oxygen?
Aerobic respiration is the type of cellular respiration that requires oxygen. This process involves the release of glucose for energy.Aerobic respiration requires oxygen to be present because it is the final electron acceptor at the end of the electron transport chain. If it is not present, then the electron can not go through the chain and fermentation will cycle instead. Fermentation is much more inefficient in producing ATP (a differenence of 32 ATP).
Is oxygen a common product to reactions in cellular respiration and fermentation?
Yes, oxygen is a common reactant in cellular respiration, specifically in aerobic respiration where it serves as the final electron acceptor in the electron transport chain. In contrast, fermentation does not require oxygen and occurs in the absence of it, utilizing alternative pathways to generate energy.
Why is oxygen nessecary in cellular respiration?
Oxygen is necessary for aerobic respiration only . It is not required in anaerobic respiration . Oxygen is final electron acceptor and it forms water at end of E.T.C.
Where does cellular respiration ends?
Aerobic respiration ends in mitochondria. Anaerobic in the cytoplasm
What prouduct is needed for cellular respiration?
Cellular respiration requires both glucose and oxygen. Glucose provides the energy for the cell and oxygen is required to be the final electron acceptor so that aerobic respiration can happen. Other molecules can enter cellular respiration and be broken down, but glucose is considered the start of this process. Oxygen is also not required, but if it is not present, then fermentation will run and this process is not nearly as efficient as aerobic respiration.
