What is the fate of the NADH H+ and FADH2 that is Synthesised during glycolysis and TCA cycle?
NADH and FADH2 are high energy compounds that are produced in the Krebs cycle. They are oxidised in the electron transport chain. Electrons released from these pass through various complexes (complex I to IV) in the electron transport chain and eventually get transferred to oxygen.
What happens to NADH during aerobic respiration?
NADH contributes to oxidation in cell processes like glycolysis to help with the oxidation of glucose. The energy stored in this reduced coenzyme NADH is supplied by the TCA cycle in the process of aerobic cellular respiration and powers the electron transport process in the membranes of mitochondria.
What happens to NADH and FADH2 after etc?
NADH and FADH2 made in the citric acid cycle (in the mitochondrial matrix) deposit their electrons into the electron transport chain at complexes I and II, respectively. This step regenerates NAD+ and FAD (the oxidized carriers) for use in the citric acid cycle.
What is the function of NADH and FADH2 in cellular respiration?
NADH and FADH2 give their electrons to proteins in the electron transport chain, which ultimately pump hydrogen ions into the intermembrane space. This chemical gradient is used to create ATP using ATP synthase.
How many ATP molecules can be produced by FADH2 and NADH H+ respectively when derived from the TCA cycle?
Theoretically ATP yield for every oxidation cycle can be maximum upto 17, as NADH produces 3 ATP, FADH2 = 2 and end product, acetyl COA governed Citric Acid Cycle produces 12 ATP.
What happens to the hydrogen ions H+) carried by NADH and FADH2?
Electrons carried by NADH + H+ and FADH2 are transferred to oxygen via a series of electron carriers, and ATPs are formed. Three ATPs are formed from each NADH + H+, and two ATPs are formed for each FADH2 in eukaryotes.
What is the fate of NADH and FADH2?
Basically, the NADH and FADH2 molecules are affixed with electrons and are transferred to the inner membrane of the mitochondria. They travel down the electron transport chain, releasing the electrons that they once had. The end result is loads of energy, approximately 34 ATP (energy molecule).

How are NADH and FADH2 converted into ATP?
The electron transport chain is located on the inner membrane of the mitochondria, as shown below. The electron transport chain contains a number of electron carriers. These carriers take the electrons from NADH and FADH2, pass them down the chain of complexes and electron carriers, and ultimately produce ATP.
Which stage of cellular respiration produces the most NADH and FADH2?
Krebs cycle So, the correct option is ' Krebs cycle'.

How many ATP does NADH and FADH2 produce?
The oxidation of one molecule of NADH thus leads to the synthesis of three molecules of ATP, whereas the oxidation of FADH2, which enters the electron transport chain at complex II, yields only two ATP molecules.
What role do NADH and FADH2 play in the electron transport chain?
NADH: High energy electron carrier used to transport electrons generated in Glycolysis and Krebs Cycle to the Electron Transport Chain. FADH2: High energy electron carrier used to transport electrons generated in Glycolysis and Krebs Cycle to the Electron Transport Chain.

What is the fate of NADH?
The electrons from NADH eventually make their way to molecular oxygen, which is reduced to water. The energy released when NADH molecules transfer electrons is ultimately used to make ATP.
What is the fate of NADH produced during aerobic glycolysis?
In the process of glycolysis, NAD+ is reduced to form NADH + H+. If NAD+ is not present, glycolysis will not be able to continue. During aerobic respiration, the NADH formed in glycolysis will be oxidized to reform NAD+ for use in glycolysis again.
In which steps are NADH and/or FADH2 produced?
So, the correct option is ' Krebs cycle'.
How many total NADH are produced during the first and second stages of aerobic respiration?
Results of the Citric Acid Cycle The energy from its chemical bonds has been stored in a total of 16 energy-carrier molecules. These molecules are: 2 ATP. 8 NADH.
During which phase of aerobic respiration is FADH2 produced?
Flavin adenine dinucleotide, or FADH2, is a redox cofactor that is created during the Krebs cycle and utilized during the last part of respiration, the electron transport chain.

How many NADH and FADH2 are made in each step of cellular respiration?
Each turn of the cycle forms three NADH molecules and one FADH2 molecule. These carriers will connect with the last portion of aerobic respiration to produce ATP molecules. One GTP or ATP is also made in each cycle.
Which produces more ATP NADH or FADH2?
FADH2 produces less ATP then NADH because NADH has more energetic electrons. FADH2 produces less ATP then NADH because the electrons for FADH2 are dropped off at the second protein of the electron transport chain.
