What are the different fates of pyruvate?
Next, show that in aerobic conditions (the presence of oxygen), pyruvate has two possible fates:
- The first is cellular respiration, which occurs in fed conditions – when glucose is abundant.
- The second is gluconeogenesis, which occurs in fasting conditions – when glucose is in demand.
What are the three metabolic fates of pyruvate?
– Acetyl CoA, which is a substrate for the citric acid cycle and fatty acid synthesis. – Oxaloacetate, which is an intermediate in the citric acid cycle and also a substrate for gluconeogenesis. – Lactate, which is produced by eukaryotes in the absence of oxygen.
What are the possible fates of pyruvate after glycolysis?
Pyruvate can enter in lactic acid fermentation and alcoholic fermentation in anaerobic condition, in aerobic condition pyruvate loss hydrogen and carbon dioxide and convert into acetyl CoA and enter into the TCA cycle, and also enter into the biosynthetic pathway.
What are the three possible fates of pyruvate generated from glycolysis?
Terms in this set (11)
- pyruvate to acetyl-coA to citric acid cycle. Fate of pyruvate under aerobic conditions (Oxygen is available) in any cell type.
- pyruvate to lactate/lactic acid.
- pyruvate to acetaldehyde to ethanol.
- pyruvate dehydrogenase complex.
- lactate dehydrogenase.
- pyruvate decarboxylase.
- alcohol dehydrogenase.
- NAD+
What are fates of pyruvate Class 10?
Pyruvate is found at the intersection of various metabolic pathways. When oxygen is present, pyruvate enters the Krebs cycle after decarboxylation and formation of acetyl CoA. When oxygen is absent, pyruvate undergoes fermentation, i.e. alcoholic or lactic acid fermentation.
What are the primary metabolic fate of pyruvate?
In most cells, the major metabolic pathway for pyruvate is mitochondrial oxidation to acetyl-CoA. Generally, the rate of mitochondrial pyruvate uptake and oxidation matches the pyruvate generation rate and the cytosol pyruvate concentration is stabilized.
What are the three possible fates of pyruvate quizlet?
Fates of Pyruvate
- conversion to acetyl CoA by PDH.
- conversion to lactate by lactate dehydrogenase.
- conversion to oxaloacetate by pyruvate carboxylase.
What is the best description of the fate of pyruvate in animal cells if there is oxygen present?
What is the best description of the fate of pyruvate in animal cells if there is oxygen present. pyruvate remains in the cytoplasm and produces ethanol.
What are the fates of pyruvate Class 10?
What are the two fates of glycolysis?
Glycolysis is used by all cells in the body for energy generation. The final product of glycolysis is pyruvate in aerobic settings and lactate in anaerobic conditions.
