30 moles of ATP are produced from 1 mole of glucose through the Krebs cycle.
How many ATP are produced per glucose?
Biology textbooks often state that 38 ATP molecules can be made per oxidized glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).
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 are produced from 2 moles of glucose?
For each molecule of glucose that is broken down, two molecules of pyruvate, two molecules of ATP, and two molecules of NADH are produced. In the absence of oxygen, pyruvate is converted to lactate, and NADH is reoxidized to NAD+.
What accounts for the different number of ATP?
What accounts for the different number of ATP molecules that are formed through cellular respiration? … The electron transport chain differs in composition between species, so different organisms will make different amounts of ATP using their electron transport chains.
How is 34 ATP produced?
The Krebs cycle takes place inside the mitochondria. The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle).
How many ATP are used in anaerobic respiration?
Aerobic vs anaerobic respiration
|Location||Cytoplasm (glycolysis) and mitochondria||Cytoplasm|
|Stages||Glycolysis (anaerobic), Krebs cycle, oxidative phosphorylation||Glycolysis, fermentation|
|ATP produced||Large amount (36 ATP)||Small amount (2 ATP)|
How many ATP are formed in etc?
The electron transport chain is the final step of cellular respiration where 34 ATP molecules are produced.
How do you calculate ATP?
Answer. ATP= Total Supplies – Total Demand in a given date range.
How many ATP are produced 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.
How is glucose metabolized by ATP?
To start the process, a glucose molecule will get modified to two pyruvate molecules in the metabolic pathway called glycolysis. … This final process of cellular respiration harnesses the energy delivered by NADH and FADH2 to drive ATP synthase to produce 34 ATP per glucose.
Why do eukaryotes only produce 36 ATP?
Why do eukaryotes generate only about 36 ATP per glucose in aerobic respiration but prokaryotes may generate about 38 ATP? A) eukaryotes have a less efficient electron transport system. … eukaryotes do not transport as much hydrogen across the mitochondrial membrane as prokaryotes do across the cytoplasmic membrane.
What happens when two moles of ATP are added to a mole of glucose?
Glucose Oxidation Energy Balance
Anaerobically, each mole of glucose produces 2 moles of ATP. … Two molecules of triose-phosphate produced per molecule of glucose yields 4–6 ATP. These, in addition to the 2 ATP made from glycolysis, gives a total of 6–8 molecules of ATP per glucose molecule. Decarboxylation of pyruvate.
How many ATP are produced in TCA cycle?
How many ATP are produced from one turn of the citric acid cycle starting with NAD+ in the electron transport chain? Step 8 is another oxidation involving the coenzyme FAD.
|Step 4 (NAD+ to E.T.C.)||3|
|Step 8 (FAD to E.T.C.)||2|
|NET (one pyruvic)||15 ATP|
|NET (2 pyruvic)||2 x 15 = 30 ATP|
How many ATP are produced from 1 NADH?
Web Link. 2.5 ATP/NADH and 1.5 ATP/FADH2 are produced in the electron transport chain. Some resources will say 3 ATP/NADH and 2 ATP/FADH2, but these values are generally less accepted now.
