How many ATP can NADH make?
For every pair of electrons transported to the electron transport chain by a molecule of NADH, between 2 and 3 ATP are generated.
For each pair of electrons transferred by FADH2, between 1 and 2 ATP are generated..
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.
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).
Which process produces the least amount of ATP?
The process of glycolysis only produces two ATP, while all the rest are produced during the electron transport chain.
How is glucose converted to ATP?
Cells convert glucose to ATP in a process called cellular respiration. Cellular respiration: process of turning glucose into energy In the form of ATP. Before cellular respiration can begin, glucose must be refined into a form that is usable by the mitochondrion.
How many ATP are made 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).
Why do we use 36 ATP instead of 38?
During cellular respiration, total energy produced is 38 ATP. Two processes take place during cellular respiration- glycolysis and krebs cycle. … In the mitochondrion, glucose is completely broken down into carbon dioxide and water and 36 ATP. So total ATP produced is 38 ATP.
Why is the actual yield of ATP likely to be lower in a cell?
In the last stage of respiration, some protons leak through the inner mitochondrial membrane back inside the matrix, so proton motive force which spins the headpiece of ATP synthase to produce ATP is decreased, hence less ATP produced.
Why do eukaryotes generate only about 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.
How many ATP are used in anaerobic respiration?

Why do prokaryotes produce 38 ATP?
Sure. In prokaryotes the usual figure is 38. Per glucose, you get 2 net ATPs from glycolysis. … We generally say that you get 3 ATPs per NADH and 2 per FADH2, so that these carriers produce a total of 30+4 = 34 ATPs….. and the Krebs cycle itself produces 2 GTPs, which are equivalent to 2 more ATPs, for a total of 38.
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.
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.
How do we get 38 ATP?
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).
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.
