What is the final electron acceptor in anaerobic respiration?
The reduced chemical compounds are oxidized by a series of respiratory integral membrane proteins with sequentially increasing reduction potentials, with the final electron acceptor being oxygen (in aerobic respiration) or another chemical substance (in anaerobic respiration).
What is the final electron acceptor in anaerobic glycolysis?
These reducing equivalents then enter the electron transport chain, leading to the production of 32 ATP per molecule of glucose. Because the electron transport chain requires oxygen as the final electron acceptor, inadequate tissue oxygenation inhibits the process of oxidative phosphorylation.
What is the final electron acceptor in anaerobic respiration quizlet?
Anaerobic respiration uses oxygen as its final electron acceptor at the end of the electron transport chain. This type of respiration uses other molecules as electron acceptors in absence of oxygen.
What is the electron acceptor for aerobic and anaerobic respiration?
This electron acceptor is either oxygen in aerobic respiration or, in anaerobic bacteria and archaea, some other inorganic molecule (Figure 8.19).
What is the final acceptor of the electron in the process?
Oxygen
Explanation: Oxygen is the final electron acceptor in the electron transport chain, showing the need for aerobic conditions to undergo such a process.
Does anaerobic respiration use NAD+ as the final electron acceptor?
Key Points. Anaerobic respiration is a type of respiration where oxygen is not used; instead, organic or inorganic molecules are used as final electron acceptors. Fermentation includes processes that use an organic molecule to regenerate NAD+ from NADH.
Which of the following can be used as a final electron acceptor for aerobic respiration quizlet?
Which of the following can be used as a final electron acceptor for aerobic respiration? – Nitrate ion, sulfate ion, and carbonate ion can all be used as a final electron acceptor.
Which is the final electron acceptor?
Oxygen is the final electron acceptor in the electron transport chain, which allows for oxidative phosphorylation. Without oxygen, the electrons will be backed up, eventually causing the electron transport chain to halt.
What is the final acceptor in aerobic respiration?
The final electron acceptor for the electron transport chain in aerobic respiration, is an oxygen molecule, O2.
Why is O2 the final electron acceptor?
The final electron acceptor is oxygen (O2). Oxygen has a high electronegativity; thus, oxygen’s high affinity for electrons makes it an ideal acceptor for low-energy electrons. With the electrons, hydrogen is added to oxygen forming water as the final product.
What is the last electron acceptor?
Oxygen is the final electron acceptor in the electron transport chain, which allows for oxidative phosphorylation. Without oxygen, the electrons will be backed up, eventually causing the electron transport chain to halt.
Is NAD+ an electron acceptor?
This group of enzymes typically uses cofactors, such as NAD, which acts as the electron acceptor. The food molecule acts as the electron donor. Due to its chemical structure, each molecule of NAD+ can accept two electrons.
Which molecule is the final electron acceptor?
What is end product of anaerobic respiration?
Anaerobic respiration occurs in the absence of oxygen and is less efficient than aerobic respiration. Unlike aerobic respiration, the end products here are ethyl alcohol as in yeasts and lactic acid as in animal cells. So the answer is ‘Alcohol and lactic acid’.
Which of the following can be used as a final electron acceptor?
FADH2 electrons enter the electron transport chain at a lower energy level. Which of the following can be used as a final electron acceptor for aerobic respiration? – Nitrate ion, sulfate ion, and carbonate ion can all be used as a final electron acceptor.
What are the final electron acceptors in aerobic anaerobic and fermentative metabolism quizlet?
At the end of the chain, the electrons join with protons and oxygen in the matrix fluid to form water. Thus oxygen is the final electron acceptor.
What is the final electron acceptor quizlet?
What is the final electron acceptor in cellular respiration quizlet?
Final electron acceptor in aerobic respiration is molecular oxygen.
What is final electron acceptor aerobic respiration glucose?
In aerobic respiration, the final electron acceptor (i.e., the one having the most positive redox potential) at the end of the ETS is an oxygen molecule (O2) that becomes reduced to water (H2O) by the final ETS carrier.
What is the terminal electron acceptor in anaerobic respiration?
In anaerobic respiration, nitrate, sulfate, or sulfur act as the terminal electron acceptor. The aerobic respiration starts with the transport of ions from NADH and FADH2 that takes place in the process of glycolysis, and the citric acid cycle through a cycle of mechanisms to a terminal acceptor of electrons.
What is a final electron acceptor?
A final electron acceptor is the last substance to obtain an electron in an electron transport chain, including the oxygen in aerobic cellular respiration, or the terminal cofactor to receive an electron in photosynthesis reaction center electron transfer domain.
What is the final electron acceptor in photosynthesis Quizlet?
What is the final electron acceptor in photosynthesis? The final electron acceptor is NADP. In oxygenic photosynthesis, the first electron donor is water, creating oxygen as a waste product.
What are the electron acceptors of aerobic bacteria?
44. All aerobic bacterial species have identical electron acceptors in their electron transport systems. 45. ATP is composed of deoxyribose, adenine, and 3 phosphate groups.
