What is the electron acceptor in glycolysis?
Once the electron donor in glycolysis gives up its electrons, it is oxidized to a compound called pyruvate. 5. NAD+ is the compound that functions as the electron acceptor in glycolysis.
What is the final electron acceptor in glycolysis?
The final electron acceptor in glycolysis is oxygen.
Is NADH an electron acceptor in glycolysis?
NADH is the electron donor and O2 is the electron acceptor. Not every donor-acceptor combination is thermodynamically possible. The redox potential of the acceptor must be more positive than the redox potential of the donor.
What is the hydrogen electron acceptor during glycolysis?
The hydrogen electron acceptor during glycolysis is FAD. 29. The diagram to the right shows the steps of glycolysis. Fill in the empty boxes of this diagram.
What is the best electron acceptor?
Oxygen
Oxygen (O2) is the best electron acceptor and is used in many aerobic reactions (reactions with oxygen).
Which compound is the final electron acceptor?
oxygen
Explanation: In cellular respiration, oxygen is the final electron acceptor. Oxygen accepts the electrons after they have passed through the electron transport chain and ATPase, the enzyme responsible for creating high-energy ATP molecules.
Which of the following in an electron acceptor?
Which of the following molecules is the final electron acceptor in the electron transport chain during cellular respiration? Explanation: Oxygen is the final electron acceptor in the electron transport chain, showing the need for aerobic conditions to undergo such a process.
How many electron carriers are in glycolysis?
two
Glycolysis, which makes two NADH from NAD+ The citric acid cycle, which makes six NADH and two FADH2 . These carriers bring their electrons to the electron transport chain, which creates a hydrogen ion gradient in intermembrane of the mitochondria.
Which of the following is an electron acceptor?
Examples of electron acceptors include oxygen, nitrate, iron (III), manganese (IV), sulfate, carbon dioxide, or in some microorganisms the chlorinated solvents such as tetrachloroethylene (PCE), trichloroethylene (TCE), dichloroethene (DCE), and vinyl chloride (VC).
How do you find the electron acceptor?
Since electron transport chains are redox processes, they can be described as the sum of two redox pairs. For example, the mitochondrial electron transport chain can be described as the sum of the NAD+/NADH redox pair and the O2/H2O redox pair. NADH is the electron donor and O2 is the electron acceptor.
Is ADP an electron acceptor?
Electrons are transferred to O2 only if ADP is concomitantly phosphorylated to ATP. The regulation of the rate of oxidative phosphorylation by the ADP level is called respiratory control or acceptor control. The level of ADP likewise affects the rate of the citric acid cycle because of its need for NAD+ and FAD.
Which is an electron acceptor in an anaerobic environment?
In anaerobic environments, different electron acceptors are used, including nitrate, nitrite, ferric iron, sulfate, carbon dioxide, and small organic molecules such as fumarate. Since electron transport chains are redox processes, they can be described as the sum of two redox pairs.
How many ATP molecules are produced during glycolysis?
ATP Yield. In a eukaryotic cell, the process of cellular respiration can metabolize one molecule of glucose into 30 to 32 ATP. The process of glycolysis only produces two ATP, while all the rest are produced during the electron transport chain.
Where does the energy from glycolysis come from?
Cellular Respiration: Glycolysis is the first pathway of cellular respiration that oxidizes glucose molecules. It is followed by the Krebs cycle and oxidative phosphorylation to produce ATP. Nearly all of the energy used by living cells comes to them from the energy in the bonds of the sugar glucose.
Which is the most common electron acceptor in bacteria?
Bacterial electron transport chains may contain as many as three proton pumps. The most common electron donors are organic molecules. There are a number of different electron acceptors, both organic and inorganic. If oxygen is available, it is invariably used as the terminal electron acceptor.
