Why the number of ATP is not known exactly?
There are three reasons that we cannot state an exact number of ATP molecules generated by one molecule of glucose.
Phosphorylation and the redox reactions are not directly coupled to each other, so the ratio of number of NADH to number of ATP is not a whole number..
Why we can’t specify an exact number of ATP are created in aerobic respiration?
Determining the exact yield of ATP for aerobic respiration is difficult for a number of reasons. … Also, some bacteria use different carriers in their electron transport chain than others and the carriers may vary in the number of protons they transport across the membrane.
Why does NADH produce more ATP?
This difference arises because they donate their electrons at different points to the electron transport chain. NADH donates it’s electrons to the first enzyme complex, that is NADH dehydrogenase complex, while FADH2 donates it’s electrons to the second enzyme complex, succinate dehydrogenase complex.
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 yields the most ATP?
The stage of cellular respiration which yields the most ATP is the electron transport chain.
How many moles of ATP are produced from 1 mole of glucose?
30 molesCellular respiration is able to produce 30 moles ATP from 1 mole glucose, and ATP contains 7.3 kcal per mole.
How do you calculate ATP efficiency?
We can determine the efficiency of ATP production by comparing the energy in ATP created by the reaction to the energy released by the reaction: where N is the number of ATP molecules formed and Ereact is the energy released as heat in the chemical reaction that is coupled with the reaction to form ATP.
Where do the 36 ATP come from?
Total ATP production from aerobic respiration: 36 ATPs for each glucose that enters glycolysis (2 from glycolysis, 2 from citric acid cycle, 32 from ETP).
How are 32 ATP produced?
The NADH pulls the enzyme’s electrons to send through the electron transport chain. The electron transport chain pulls H+ ions through the chain. From the electron transport chain, the released hydrogen ions make ADP for an end result of 32 ATP.
How many ATP are formed in glycolysis?
2 ATPDuring 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.
Does glycolysis require oxygen?
Glycolysis requires no oxygen. It is an anaerobic type of respiration performed by all cells, including anaerobic cells that are killed by oxygen. For these reasons, glycolysis is believed to be one of the first types of cell respiration and a very ancient process, billions of years old.
What is the net gain of ATP in glycolysis?
Overall, glycolysis produces two pyruvate molecules, a net gain of two ATP molecules, and two NADH molecules.
Why is the maximum per glucose ATP count as 36 38 ATP?
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.
What is NADH ATP worth?
The 3 ATPs per NADH is an estimate made from lab experiments under carefully-defined conditions, and it’s quite likely that the actual values vary considerably in the cell itself! Hope this helps.
What process does not produce ATP?
Aerobic respiration is the final way that ATP is formed. … Without oxygen, aerobic respiration converts to anaerobic respiration, which only produces 2 ATP compared to aerobic respirations 34. Anaerobic respiration results in lactate build up in animals, or alcohol and carbon dioxide build up in yeast and plants.
What stage of cellular respiration produces the most ATP?
Krebs cycleThe 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). The electron transport chain takes place in the mitochondria.
How many net ATP are made in glycolysis quizlet?
two ATPGlycolysis has a net energy yield of two ATP molecules and two NADH molecules.
Can you then calculate how many ATP?
There is a theoretical maximum of 38 ATP produced from a single glucose molecule: 2 NADH produced in glycolysis (3 ATP each) + 8 NADH produced in Krebs cycle (3 ATP each) + 2 FADH2 produced I don’t know where (2 ATP each) + 2 ATP produced in the Krebs cycle + 2 ATP produced in glycolysis = 6 + 24 + 4 + 2 + 2 = 38 ATP, …
