How many ATP are produced per each molecule of glucose?
Thus the net yield is two ATPs per glucose molecule. The remaining 34 molecules of ATP generated during the complete aerobic metabolism of glucose are synthesized during oxidation of pyruvate to CO2 and H2O in mitochondria.
What is the total number of ATP produced from a molecule of glucose in the process of aerobic respiration in eukaryotic cells?
Overall, the theoretical maximum yield of ATP made during the complete aerobic respiration of glucose is 38 molecules, with four being made by substrate-level phosphorylation and 34 being made by oxidative phosphorylation (Table 1).
Why is ATP 36 or 38?
In eukaryotic cells, the theoretical maximum yield of ATP generated per glucose is 36 to 38, depending on how the 2 NADH generated in the cytoplasm during glycolysis enter the mitochondria and whether the resulting yield is 2 or 3 ATP per NADH.
How many ATP does glucose produce in glycolysis?
During glycolysis, glucose ultimately breaks down into pyruvate and energy; a total of 2 ATP is derived in the process (Glucose + 2 NAD+ + 2 ADP + 2 Pi –> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O). The hydroxyl groups allow for phosphorylation. The specific form of glucose used in glycolysis is glucose 6-phosphate.
How many ATP molecules are produced in glycolysis?
Glycolysis: Glucose ( 6 carbon atoms) is split into 2 molecules of pyruvic acid (3 carbons each). This produces 2 ATP and 2 NADH.
How many ATP are produced per glucose in anaerobic respiration?
Summary. Aerobic respiration is far more energy-efficient than anaerobic respiration. Aerobic processes produce up to 38 ATP per glucose. Anaerobic processes yield only 2 ATP per glucose.
Why do eukaryotes only produce 36 ATP?
Complete answer: In prokaryotes, there are no mitochondria, the whole process of respiration occurs within the cytoplasm so no ATP is consumed in transporting across the organelle. Therefore, 38 ATPs are made from one glucose in bacteria while 36 are made in a eukaryotic cell.
How are 36 ATP molecules produced per glucose molecule during respiration?
Out of 36 ATP molecules produced per glucose molecule during respiration. Explanation: Out of 36 ATP molecules 2 are produced in glycolysis outside mitochondria and the rest of the ATP molecules are produced inside mitochondria in the Krebs cycle and electron transport chain (respiratory chain).
How many ATP molecules are produced from one glucose?
First, all the NADH2 from 1 glucose-. 2 are formed from glycolysis. 2 from link reaction. 6 from Kreb’s cycle. There are also 2 FADH2 obtained in Kreb’s cycle. Since 1 NADH2 = 3 ATP and 1 FADH2 = 2 ATP, total ATP formed are 34.
What is the net gain of ATP in cellular respiration?
Most biochemists agree that in prokaryotic microorganisms, a total of 36 molecules of ATP can be produced during cellular respiration. In eukaryotic cells, the number is 34 molecules of ATP. Two molecules of ATP are produced as the net gain of glycolysis, so the grand total is 38 molecules of ATP (36 in eukaryotes).
How many ATPs are obtained from aerobic respiration?
2 more ATP are directly obtained from glycolysis and 2 from substrate level phosphorylation (ie, without entering ETC) of 2 GTPs formed in Kreb’s cycle. Thus, 34 from ETC, and 4 from elsewhere make total 38 ATPs from aerobic respiration.
