Final electron acceptor in aerobic respiration is molecular oxygen. Aerobic occurs in mitochondira. Anaerobic occurs in cytoplasm.
What is the final electron acceptor in aerobic and anaerobic?
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).
Is pyruvate the final electron acceptor in aerobic respiration?
Answer and Explanation: The final electron acceptor in aerobic respiration is molecular oxygen.
What is the final electron acceptor in anaerobic?
In anaerobic environments sulfate serves as terminal electron acceptor and is reduced to sulfide, giving rise to both the formation of metal sulfides in sediments and the evolution of hydrogen sulfide gas.
What is the final electron acceptor during aerobic respiration quizlet Related Questions
What is the final electron acceptor during 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.
Is NAD+ an electron acceptor?
NAD+ acts as an electron and hydrogen acceptor and NADH acts as a hydrogen and electron donor.
What is the first electron acceptor of aerobic respiration?
This electron acceptor is either oxygen in aerobic respiration or, in anaerobic bacteria and archaea, some other inorganic molecule (Figure 8.19).
Why is pyruvate the final electron acceptor?
In lactic acid fermentation, NADH is the electron carrier that ultimately carries them to pyruvate. Pyruvate is reduced to lactic acid, and thus, acted as the final electron acceptor.
Is ATP the final electron acceptor?
Explanation: Oxygen is the final electron acceptor in the electron transport chain, showing the need for aerobic conditions to undergo such a process. ATP is produced as a product of the electron transport chain, while glucose and CO2 play a role in earlier processes of cellular respiration.
What is the final electron acceptor in mitochondria?
Oxygen is the terminal electron acceptor in the mitochondrial electron transport chain and therefore is required for the generation of energy through oxidative phosphorylation.
Is NAD+ or NADH an electron carrier?
NADH is actively carrying electrons and NAD+ is not carrying electrons. NADH is the reduced form of NAD+. NAD+ is the oxidized form of NADH.
Is NAD+ or NADH the electron donor?
NAD+ accepts electrons from food molecules, transforming it into NADH. NADH donates electrons to oxygen, converting it back to NAD+. The relative proportion of these two molecules depends on the energy state of the cell, with more NADH being present in a fed state.
Is NADH a electron acceptor?
The NADH dehydrogenase complex (generally known as complex I) is the largest of the respiratory enzyme complexes, containing more than 40 polypeptide chains. It accepts electrons from NADH and passes them through a flavin and at least seven iron-sulfur centers to ubiquinone.
Which of the following is an acceptor in aerobic respiration?
Oxygen is the terminal electron acceptor in aerobic respiration.
What is the final electron acceptor quizlet?
Oxygen is the final electron acceptor, and it has the highest affinity for electrons. When oxygen accepts an electron, it is reduced to water.
What is the electron acceptor in glycolysis?
Acetaldehyde, the derivative of pyruvate, is the component that acts as an electron acceptor in the fermentation process for accepting the electrons produced from NADH.
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.
Is pyruvate a donor or acceptor?
The results suggest that pyruvate fermentation by S. oneidensis MR-1 cells represents a combination of substrate-level phosphorylation and respiration, where pyruvate serves as an electron donor and an electron acceptor.
Which is the final acceptor?
The final electron acceptor is oxygen (O2), it has a high electronegativity and accepts low-energy electrons. Hydrogen is combined with oxygen, forming water as the final product.
What is the final electron acceptor in the chloroplast?
The final electron acceptor in this electron-transport chain is the second photosystem, photosystem I, which accepts an electron into the electron-deficient hole created by light in the chlorophyll molecule in its reaction center.
