Are only 2 ATPs produced for each NADH molecule that enters the last stage of respiration?
The NADH molecule produces of 2 ATPs during the last stage of respiration. Some think that three ATPs are created from the NADH, however, the last stage of respiration is different than ATP and NADH during electron transfers.
How the 38 atps are formed?
It gets produced form glucose aerobic metabolism that consists of 4 steps: 1.glycolisis = 2 ATPs +2 NADH 2.pyruvate oxidative decarboxilation = 1 NADH *2 (because we have 2 pyruvates from the glycolisis) 3. Krebs cycle = (3NADH + 1FADH + 1ATP) * 2 4.Cellular respiration cycle - process where all the NADH and FADH are converted to ATPs. Each NADH = 3ATP, but FADH=2ATP. Thus we get: 1. 8 ATPs 2. 6 ATPs (3*2) 3. 24 ATPs (12*2) --------------------- 38 ATPs
How many ATP's and NADH's are made for each molecule of glucose to breakdown?
3 ATP per NADH and 2 ATP per FADH2 through oxidative phosphyrolation in mitochondria
What is the end product of each step of cellular respiration?
Glycolysis: 2 pyruvates, 4 ATP (net gain of 2), 2 NADH Krebs Cycle: products per glucose molecule: 4 CO2, 6 NADH, 2ATP, 2FADH2 Electron Transport Chain: on average, each NADH will produce 3 ATP, and each FADh2 will produce 2 ATp. Water is also produced... 10 NADH= 30 ATP, 2FADH2= 4 ATP (plus 2 ATP from glycolysis and 2 ATP from Kreb's Cycle) total of 38. One entire round of cellular respiration produces (at the most) 38 ATP. hope this helps!
How many atps are released in respiration?
A net total of 36-38 ATPs are released during aerobic respiration, while only 2 ATPs are released during anaerobic respiration.

Four molecules of glucose would give a net yield of?
In general terms we can say that for every molecule of glucose 38 molecules of ATP are formed. Here is how it works: The 12 electron pairs involved in glucose oxidation are not transferred directly to O2. Rather, they are transferred to the coenzymes NAD+ and FAD to form 10 NADH + 2 FADH2 in the reactions catalyzed by the glycolytic enzyme glyceraldehyde-3-phosphate dehydrogenase, pyruvate dehydrogenase, and the citric acid cycle enzymes isocitrate dehydrogenase, a-ketoglutarate dehydrogenase, succinate dehydrogenase, and the malate dehydrogenase. The electrons then pass into the electron transport chain where, through reoxidation of NADH and FADH2, they participate in the sequential oxidation-reduction of per 10 redox centers before reducing O2 to H2O. In this process, protons are expelled from the mitochondrion. The free energy stored in the resulting pH gradient drives the synthesis of ATP form ADP and Pi through oxidative phosphorylation. Reoxidation of each NADH results in the synthesis of 3 ATPs, and reoxidation of FADH2 yields 2 ATPs for a total of 38 ATPs for each glucose completely oxidized to CO2 and H2O (including the 2 ATPs made in glycolysis and the 2 ATPs made in the citric acid cycle).The stoichiometric analysis can be expressed as:C6H12O6 + 38ADP + 38Pi + 6O2 - 6CO2 + 44H2O + 38ATPMoreover, the net gain of a single molecule of glucose can be analyzed as follows:Glucolysis produces directly 2 NADH, 4 ATPs, and 2 ATPs are consumed, giving a yield of 8 ATPs.Pyruvate oxydation produces 2 NADH to yield 6 ATPs.Acetyl-CoA oxydation (citric acid cycle) produces 6 NADH to yield 18 ATPs, 2 FADH2 to yield 4 ATPs, 2 ATPs or 2 GTPs formed directly, within the citric acid cycle, to yield 2 ATPs.Therefore, the total yield per molecule of glucose is 38.Finally, we have to consider that the final yield of ATP from glucose can be 36 instead of 38 because the number depends upon on which shuttle system is used to transfer reducing equivalents (2 NADH formed in cytosol during glycolisis) into the mitochondrial matrix.
What happen during glycolysis?
During glycolysis, a process that occurs in the cytoplasm of cells, glucose is broken down into pyruvate molecules. This process produces ATP and NADH, which can be used by the cell for energy production. Glycolysis is the first step in both aerobic and anaerobic cellular respiration pathways.
During glycolysis what is the overall gain of the ATP per glucose molecule?
During glycolysis, the overall gain of ATP per glucose molecule is 2. While glycolysis produces 4 ATPs, it uses 2 ATPs in the process.
What During glycolysis what overall gain of ATP per glucose molecule?
During glycolysis, the overall gain of ATP per glucose molecule is 2. While glycolysis produces 4 ATPs, it uses 2 ATPs in the process.
How many NADH molecules are produced during the stages of aerobic respiration?
10 NADH molecules are produced in total. 2 during glycolysis, 2 during link reaction (1 per pyruvate, 2 per glucose molecule), and 6 during the Krebs cycle. None during the electron transport chain.
How many ATP molecules are produced from beta oxidation of arachidic acid?
20 ATP from 8 NADH 12 ATP from 12 FADH2 9 acetyl co-A --> 9 GTP, 67,5 ATP from 27 NADH, 13,5 ATP from 9 FADH2 minus 2 ATP to start beta-oxidation = 120 ATP
What During glycolysis what is the overall gain of ATP per glucose molecule?
During glycolysis, the overall gain of ATP per glucose molecule is 2. While glycolysis produces 4 ATPs, it uses 2 ATPs in the process.
How many ATP molecules does each NADH molecule yield?
In glycolysis of cellular respiration, NADH produces 2ATP because one ATP is used to transport a molecule of NADH into the mitochondria and continue with aerobic respiration. However, in pyruvate decarboxylation and the Krebs cycle, each NADH yields 3ATPs. FADH2 yields 2 ATPs.
Is nadph formed during the Krebs cycle?
Definitely! Per ever glucose that passes through cellular respiration, 6 NADH are produced during the Krebs Cycle. (Precisely, 3 NADH are produced per turn of the Krebs Cycle and 1 glucose molecule causes the Krebs Cycle to turn twice. Therefore, 2 turns * 3 NADH per turn = 6 NADH)
What are the products of glycolysis per glucose molecule?
The products of glycolysis per glucose molecule are 2 molecules of ATP, 2 molecules of NADH, and 2 molecules of pyruvate.
