Why do we test for the presence of indole rather than pyruvic acid as the indicator of tryptophanase activity?
Indole is a direct byproduct of tryptophan metabolism by tryptophanase, making it a reliable indicator of tryptophanase activity. Pyruvic acid is a common metabolic intermediate and can be produced through various pathways not specific to tryptophan metabolism, making it less specific as an indicator for tryptophanase activity specifically.
What is Pyruvic Acid?
Pyruvate or Pyruvic acid is the end product of the anaerobic portion of glycolysis. If the cell has enough oxygen to run aerobic respiration then pyruvate is converted into acetyl-CoA and carbon dioxide byt eh enzyme pyruvate carboxylase. If there isn't enough oxygen in the cell, then pyruvate is converted to lactic acid in order to free up some of the required reactants(NAD+). This allows anaerobic glycolysis to continue.an ester or salt of pyruvic acid.Pyruvate is an organic acid, which can be formed from glucose through glycolysis, can form lactic acid, provides energy for cells in the citric acid cycle, and can be converted to fatty acids or carbohydrates.
Why is excess pyruvic acid produced during prolonged strenuous exercise?
Excess pyruvic acid is produced during prolonged strenuous exercise because the body relies more heavily on anaerobic respiration due to the insufficient supply of oxygen to meet energy demands. This causes an accumulation of pyruvate, the end product of glycolysis, which is then converted to lactic acid in order to regenerate NAD+ for continued ATP production.
Is hydrochloric acid an end product of fermentation?
No, hydrochloric acid is not an end product of fermentation. Fermentation typically produces alcohol, carbon dioxide, and organic acids such as lactic acid or acetic acid, depending on the type of fermentation process occurring. Hydrochloric acid is a mineral acid that is produced in the stomach to aid in digestion.
What is the end product of oxidation?
The end product of oxidation depends on the substance undergoing oxidation. For example, the end product of oxidation of organic compounds can be carbon dioxide and water, while the oxidation of metals can result in metal oxides. In biological systems, the end product of oxidation of glucose is carbon dioxide and water, which releases energy in the form of ATP.
What is the end of product of the breakdown of pyruvic acid?
Acetyl-Coa
What three carbon compound is the most common end product of glycolysis?
Pyruvate is the most common end product of glycolysis.
Is pyruvic acid considered an end product of aerobic cellular respiration?
No, pyruvic acid is not considered an end product of aerobic cellular respiration. In aerobic respiration, pyruvic acid is further oxidized to produce carbon dioxide and water in the citric acid cycle and the electron transport chain.
End product of the aerobic catabolism of glucose?
The end product of the aerobic catabolism of glucose is pyruvic acid.
What acid is produced as an end product of glycolysis?
Glycolysis takes place in Aerobic respiration which uses pyruvic acid during it's cycle however at the end of this process (electron transport chain where ATP is made and O2 is the final electron acceptor) H2O is the "end" product. FERMENTATION is used in Anaerobic respiration which uses a carbon of Glucose to begin the process which results in the production of PYRUVIC ACID and the creation of 2 ATP. Glycolysis DOES NOT produce and acid....
What is the end product of glycolisis?
pyruvic acid, NADPH, and ATPTwo from each is given off.Two ATPs are used in the reaction
Can pyruvic acid use in the Krebs cycle?
The pyruvic acid that is produced by glycolysis is used as the initial input for the Krebs Cycle (also called citric acid cycle). In the initial step of the Krebs Cycle, the pyruvic acid is converted to acetyl-CoA via pyruvate decarboxylation. This continues a series of chemical reactions leading to the production of 2 ATP molecules.
What is lactic acid and why does this increase the muscles?
When muscles are working hard and not enough oxygen is available the Kreb's cycle shuts down and the end product of glycolysis, pyruvic acid gets converted to lactic acid.
The starting substance of the Kreb's cycle which is regenerated at the end of the cycle is?
Pyruvic acid
Do all microorganisms use pyruvic acid in the same way?
No, not all microorganisms use pyruvic acid in the same way. Pyruvic acid is a key molecule in cellular respiration and can be converted into different compounds depending on the organism and its metabolic pathways. Some microorganisms may further metabolize pyruvic acid through fermentation, while others may oxidize it completely through the citric acid cycle.
Why do we test for the presence of indole rather than pyruvic acid as the indicator of tryptophanase activity?
Indole is a direct byproduct of tryptophan metabolism by tryptophanase, making it a reliable indicator of tryptophanase activity. Pyruvic acid is a common metabolic intermediate and can be produced through various pathways not specific to tryptophan metabolism, making it less specific as an indicator for tryptophanase activity specifically.
Show how alanine could be deaminated to give the end-products indicated alanine pyruvic acid of what value is deamination to a microbe?
Alanine can be deaminated by the enzyme alanine deaminase to form pyruvic acid. This reaction involves the removal of the amino group (-NH2) from alanine. Deamination is valuable to a microbe as it provides a source of carbon for energy production through the production of pyruvic acid, which can enter the citric acid cycle or be used in gluconeogenesis.
