What is the maximum number of ATP produced from the complete oxidation of 3 molecules of glucose?
The complete oxidation of one molecule of glucose produces 36-38 ATP. Therefore, the complete oxidation of 3 molecules of glucose would produce 108-114 ATP in total.
When an organism such as yeast lives by fermation it converts the pyruvic acid from glycolsis into a different compound such as alcohol Why doesn't it secrete pyruvic acid directly?
Yeast metabolizes pyruvic acid through fermentation to produce alcohol because this process enables it to regenerate NAD+, necessary for sustaining glycolysis in the absence of oxygen. By converting pyruvic acid into alcohol, yeast can maintain its energy production despite limited oxygen availability. Additionally, secreting pyruvic acid directly would not serve the same energy-generating purpose as fermentation.
What happen to pyruvic acid molecule in the mitochondrial matrix?
Pyruvic acid (CH3COCOOH) is an organic acid. It is also a ketone, as well as being the simplest alpha-keto acid. The carboxylate (COOH) ion (anion) of pyruvic acid, CH3COCOO-, is known as pyruvate, and is a key intersection in several metabolic pathways. It can be made from glucose through glycolysis, supplies energy to living cells in the citric acid cycle, and can also be converted to carbohydrates via gluconeogenesis, to fatty acids or energy through acetyl-CoA, to the amino acid alanine and to ethanol.
What would happen if an organism lacked hexokinase?
If an organism lacked hexokinase, it would be unable to phosphorylate glucose to glucose-6-phosphate, which is the first step in glucose metabolism. This would impair the organism's ability to utilize glucose for energy production.
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
What is the maximum number of ATP produced from the complete oxidation of 3 molecules of glucose?
The complete oxidation of one molecule of glucose produces 36-38 ATP. Therefore, the complete oxidation of 3 molecules of glucose would produce 108-114 ATP in total.
What is the pH of glucose solution?
Glucose is a neutral molecule, so a solution of pure glucose would have a pH of 7. However, when glucose is dissolved in water, it can undergo a slight oxidation reaction to form gluconic acid, which can lower the pH slightly below 7. Generally, the pH of a glucose solution would be close to neutral, around 6.8-7.4.
How many atoms of carbon hydrogen and and oxygen are in two molecules of pyruvic acid?
Each molecule of pyruvic acid has 3 carbon atoms, 4 hydrogen atoms, and 3 oxygen atoms. Therefore, two molecules of pyruvic acid would have a total of 6 carbon atoms, 8 hydrogen atoms, and 6 oxygen atoms.

Does oxygen ever have a 3- oxidation number?
No, oxygen will never have a -3 oxidation number. If it had a -3 oxidation number, it would not have a full octet. It would have a +1 charge, therefore making it not happy.
What compound has the atom with the highest oxidation number?
The compound with the highest oxidation number would be an oxide of fluorine, such as OF₂. In this compound, the oxidation state of fluorine is +2, which is the highest oxidation state observed for fluorine.
What is the oxidation number of ferric oxide?
The oxidation number of iron in ferric oxide (Fe2O3) is +3. This is because oxygen typically has an oxidation number of -2, and since there are 3 oxygen atoms in Fe2O3, the total oxidation number from oxygen is -6. In order for the compound to be neutral, the oxidation number of iron must be +3 to balance out the -6 from the oxygen atoms.
Oxidation number of no3?
If you are referring to the nitrate ion, NO3-, the oxidation number of oxygen would be O2- and nitrogen would be N5+. If you are talking about nitrogen trioxide NO3, the oxidation number of oxygen would be O2- and nitrogen would be N6+. Edit: Nitrogen trioxide does not exist in its free state.
What is the oxidation number of the element in question?
The oxidation number of an element is the charge it would have if all its bonds were ionic.
What is the oxidation number for 6H?
The oxidation number for hydrogen (H) is typically +1. Therefore, the total oxidation number for 6 hydrogen atoms would be +6.
