What is the terminal electron acceptor in aerobic cellular respiration?
NAD+ is the first electron acceptor in cellular respiration (O2 is the final acceptor).
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 cellular respiration call an aerobic process?
Cellular respiration is called an aerobic process because it requires oxygen to produce energy in the form of ATP. The final stages of cellular respiration, the electron transport chain and oxidative phosphorylation, can only occur in the presence of oxygen. The term "aerobic" refers to the use of oxygen in a process.
What happens if an organism performs cellular respiration without oxygen?
If an organism performs cellular respiration without oxygen, it undergoes anaerobic respiration. This process yields less ATP compared to aerobic respiration and produces lactic acid or ethanol as byproducts. Anaerobic respiration is less efficient because oxygen is not available to act as the final electron acceptor in the electron transport chain.
How are steps of cellular respiration different when it is anaerobic respiration?
In anaerobic respiration, the final electron acceptor is an inorganic molecule other than oxygen, such as sulfate or nitrate, whereas in aerobic respiration, the final electron acceptor is oxygen. As a result, anaerobic respiration produces less ATP compared to aerobic respiration. Anaerobic respiration also produces byproducts like lactic acid or ethanol.
Which of these is not a final product of aerobic cellular respiration?
Water is not a final product of aerobic cellular respiration. The final products are carbon dioxide and water.
Is ADP is the final energy product of aerobic cellular respiration?
No. That's ATP.
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.
