How many ATP does acetyl CoA produce in the TCA cycle?
Acetyl CoA produces 12 ATP molecules accounting for 3 NADH (9 ATP), 1 FADH2 (2 ATP) and 1 GTP (1 ATP) in the TCA cycle and oxidative phosphorylation in the electron transport system. Where Does the Krebs Cycle Take Place in the Mitochondria?
How many ATP are in 18 C fatty acids?
1 NADH in electron transport chain = 2.5 ATP, aproximately 3 ATP 1 FADH2 in electron transport chain = 1.5 ATP, approximately 2 ATP therefore 18 C fatty acids complete breakdown = 126 to 153 ATP Want to get more out of Visual Studio?

How many acetyl CoA go through Krebs?
I will give you a hint: 7 acetyl coA and 1 propionyl coA go through Krebs, minus 2 ATP for activation of the fatty acid. The complete conversion of a fatty acyl CoA to two carbon fragments of acetyl CoA always produces one more molecule of acetyl CoA than of FADH2 or NADH.
How many ATP are produced from beta-oxidation?
Adding up the NADH and FADH2, the electron transport chain ATP production from beta-oxidation and the citric acid cycle looks like this: 8 (beta-oxidation) + 27 (TCA) = 35 NADH X 2.5 ATP/NADH = 87.5 ATP 8 (beta-oxidation) + 9 (TCA) = 17 FADH2 X 1.5 ATP/FADH2 = 25.5 ATP Total ATP from complete oxidation of an 18 carbon fatty acid: lets do the math…
Does acetyl-CoA produce 10 ATP?
From the Beta oxidation process: The P/O ratios, which give the number of ATP produced per molecule, are 1.5 for FADH 2, 2.5 for NADH, and 10 for acetyl-CoA.
How many ATPs are produced from the complete oxidation of 2 acetyl-CoA?
So, the correct answer is 12 ATP.
How many ATP are produced from glucose to acetyl-CoA?
2 ATPsThe acetyl CoA thus produced enters the Krebs cycle or TCA cycle. 2 ATPs are produced in the TCA cycle per glucose molecule (2 acetyl CoA).
How many ATP are produced from the synthesis of acetyl-CoA from pyruvate?
Note that this process completely oxidizes 1 molecule of pyruvate, a 3 carbon organic acid, to 3 molecules of CO2. During this process, 4 molecules of NADH, 1 molecule of FADH2, and 1 molecule of GTP (or ATP) are produced.
How many total ATP are produced through it is only from two molecules of acetyl CoA in aerobic respiration?
So, the correct answer is 12 ATP.
How do you calculate the amount of ATP produced?
Calculation of ATP production in aerobic respiration:Glycolysis: 8 ATP (2 ATP + 2 NADH = 6 ATP, i.e. 3 ATPs per NADH molecule)Decarboxylation of pyruvate to acetyl CoA: 6 ATP (2 NADH = 6 ATP, i.e. 3 ATP per NADH molecule)Krebs cycle: 24 ATP (6 NADH = 18 ATP, 2 FADH2 = 4 ATP (2 ATP per FADH2) and 2 ATP)Also Check:
How are 36 ATP produced?
The citric acid cycle produces 36 ATP molecules. So, in aerobic respiration, a total of 38 molecules of ATP are created, with 2 ATP molecules formed outside the mitochondria.
How are 32 ATP produced?
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.
How is 34 ATP produced?
A very efficient cell can produce a total of 38 ATP from a single glucose molecule. If we consider that glycolysis and the Krebs Cycle generate a total of 4 of those ATPs, that means that the ETC can produce 34 ATP molecules in one go.
How many ATP are produced during the conversion of pyruvate to acetyl CoA quizlet?
one ATP, three NADH, and one FADH2 are produced.
What are the products of acetyl CoA formation?
So the two products formed during the formation of acetyl CoA are CO2 and NADH.
How much ATP is produced in citric acid cycle?
The citric acid cycle also produces 2 ATP by substrate phosphorylation and plays an important role in the flow of carbon through the cell by supplying precursor metabolites for various biosynthetic pathways.
What is the process of changing fatty acids into acetyl CoA?
Glycerol is changed into one of the intermediate products of glycolysis, so enters the cell respiration pathway. Fatty acids are changed in a series of reactions called beta-oxidation into acetyl CoA molecules, which enter cell metabolism at the Kreb's Cycle.
What can 9 acetyl-coas produce?
Those 9 acetyl-CoAs can continue into the citric acid cycle, where they can produce: 9 GTP. 9 FADH2. 27 NADH. Adding up the NADH and FADH2, the electron transport chain ATP production from beta-oxidation and the citric acid cycle looks like this: NADH.
How many passes does 18-C stearic acid need to break down?
– Thus, the breakdown of 18-C stearic acid requires 8 passes through the spiral, and produces 9 acetyl CoA's, but only 8 FADH2's and 8 NADH's.
How many cycles of beta oxidation are needed to completely oxidize the 18-carbon fatty acid above?
To completely oxidize the 18-carbon fatty acid above, 8 cycles of beta-oxidation have to occur. This will produce:
How many cycles of beta oxidation are needed to oxidize fatty acids?
Improve your health skill set with a scientific understanding of the effects of exercise on the body. To completely oxidize the 18-carbon fatty acid above, 8 cycles of beta-oxidation have to occur.
Where does beta oxidation occur?
Beta oxidation of fatty acids occurs in the mitochondrion for short, medium, and long chain fatty acids. Stearic acid (18 carbons) is a long chain fatty acid (LCFA). The very long chain fatty acids (VLCFA; 22 or more carbons) have initial beta oxidation in peroxisomes, down to short or medium chain length.
Where does NADH reducing equivalents go?
The NADH reducing equivalents produced in later steps in peroxisomes is exported to the cytoplasm where it can participate in “NADH shuttles” that transfer reducing equivalents from the cytoplasm to the mitochondria and thus make ATP.
