How many carbons from 1 glucose molecule enter 1 round of the Krebs cycle?
Two carbons from one glucose molecule enter one round of the Krebs cycle in the form of acetyl-CoA, which is derived from pyruvate through pyruvate dehydrogenase.
What does one pyruvate produce after the Krebs cycle?
One pyruvate molecule produces 3 molecules of carbon dioxide, 4 molecules of NADH, 1 molecule of FADH2, and 1 molecule of ATP after completing the Krebs cycle. These molecules are important for generating energy through the electron transport chain.
What are the Products of the Krebs cycle per molecule of pyruvate?
For one molecule of Pyruvate (pyruvic acid) the Krebs cycle produces 2 molecules of carbon dioxide (CO2), 3 molecules of NADH, one molecule of FADH2, and one molecule of ATP.Also, the change from pyruvate to acetyl CoA produces one NADH and one carbon dioxide molecule; CoA is recycled in and out of the cycle.
How many ATP and NADH molecules are produced from each molecule of glucose in the citric acid cycle only?
In my textbook it says that 1 molecule of ATP and 3 molecules of NADH are made from 1 molecule of pyruvate, via the citric acid cycle. However, since the question is asking for 1 molecule of GLUCOSE, the answer would be 2 ATP and 6 NADH since the oxidation of glucose produces TWO molecules of pyruvate, the amount of ATP and NADH would have to be doubled. I actually have this EXACT question on my exam... hmmm... do I know you by chance? o__O
How does many ATP produced from 2 moles of pyruvate in Krebs cycle?
For each mole of pyruvate, the Krebs cycle produces 3 molecules of NADH, 1 molecule of FADH2, and 1 molecule of ATP. Therefore, from 2 moles of pyruvate, the Krebs cycle produces 6 molecules of NADH, 2 molecules of FADH2, and 2 molecules of ATP. These NADH and FADH2 molecules go on to generate more ATP through oxidative phosphorylation in the electron transport chain.
How many carbons from 1 glucose molecule enter 1 round of the Krebs cycle?
Two carbons from one glucose molecule enter one round of the Krebs cycle in the form of acetyl-CoA, which is derived from pyruvate through pyruvate dehydrogenase.
What are the products of acetyl CoA formation from a molecule of pyruvate?
The products of acetyl CoA formation from a molecule of pyruvate are acetyl CoA, NADH, and carbon dioxide. This process occurs during the mitochondrial pyruvate dehydrogenase complex reaction, where pyruvate is converted to acetyl CoA by a series of enzymatic reactions.
How many bonds are in 2 pyruvate molecule?
Each pyruvate molecule has a total of 3 carbon atoms, 4 hydrogen atoms, and 2 oxygen atoms, resulting in a total of 6 carbon-hydrogen (C-H) bonds, 2 carbon-oxygen (C-O) bonds, and 1 oxygen-hydrogen (O-H) bond. Therefore, a single pyruvate molecule contains 9 bonds. Consequently, 2 pyruvate molecules would have a total of 18 bonds.
What does one pyruvate produce after the Krebs cycle?
One pyruvate molecule produces 3 molecules of carbon dioxide, 4 molecules of NADH, 1 molecule of FADH2, and 1 molecule of ATP after completing the Krebs cycle. These molecules are important for generating energy through the electron transport chain.

What is the difference between 1-2 vs 1-4 addition to dienes?
In 1-2 addition to dienes, two atoms or groups add to adjacent carbons in the diene molecule, while in 1-4 addition, the atoms or groups add to carbons that are separated by one carbon atom in the diene molecule.
What are the hydrocarbons prefix?
The prefixes for naming hydrocarbons are based on the number of carbon atoms in the molecule. They include: meth- (1 carbon), eth- (2 carbons), prop- (3 carbons), but- (4 carbons), pent- (5 carbons), hex- (6 carbons), hept- (7 carbons), oct- (8 carbons), non- (9 carbons), dec- (10 carbons).
How is the process of numbering carbons in sugars carried out?
In sugars, the process of numbering carbons is carried out by starting at the end of the molecule closest to the carbonyl group (aldehyde or ketone). The carbon closest to the carbonyl group is assigned the number 1, and subsequent carbons are numbered sequentially along the carbon chain.
How many pyruvate molecules are produced per glucose molecule during glycolysis?
Glucose contains six carbon atoms, whereas pyruvate only contains three, so it is possible to derive two pyruvate molecules (3+3 carbon atoms) from one glucose molecule (=6 carbon atoms). During the early stages of glycolysis, the glucose is converted into Fructose-1,6-bisphosphate. This molecule also has six carbon atoms, and is split by an enzyme called 'fructose biphosphate aldolase' into two separate molecules containing three carbon atoms: glyceraldehyde-3-phosphate and dihydroxyacetone phosphate. It is the glyceraldehyde-3-phosphate that is later converted into pyruvate, accounting for the first pyruvate molecules from glucose. However, the other 3-carbon molecule, dihydroxyacetone phosphate, is kept in equilibium with glyceraldehyde-3-phosphate by an enzyme known as 'triose phosphate isomerase', so that this is eventually converted into pyruvate as well. The result being two pyruvate molecules per glucose molecule.
How many acetate groups are produced from one glucose during cellular respiration?
Each glucose molecule is converted to two molecules of pyruvate through glycolysis. Each molecule of pyruvate can then be converted to 1 acetyl CoA for a total of 2 acetly groups from 1 glucose
How many atoms make up 1 molecular of vinegar?
Vinegar is acetic acid or CH3COOH and there are totally 8 atoms (2 carbons, 2 oxygens and 4 hydrogens) in one molecule of vinegar.
