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).

What is the total ATP produced 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).
Does cellular respiration produce 36 or 38 ATP?
The theoretical maximum yield of ATP for the oxidation of one molecule of glucose during aerobic respiration is 38. In terms of substrate-level phosphorylation, oxidative phosphorylation, and the component pathways involved, briefly explain how this number is obtained.
How is 36 ATP formed?
During respiration, 36 ATP molecules are produced per glucose molecule. 2 molecules of ATP are produced outside mitochondria i.e., during glycolysis and other 34 molecules of ATP are produced inside mitochondria from Krebs cycle.
How many ATP is 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).
How many ATP are produced from 1 NADH?
In cytoplasm, one molecule of NADH is equivalent to 2 ATP. Inside the mitochondria, one molecule of NADH is equivalent to 3 ATP.
Why is the total count about 36 or 38?
During chemiosmosis, the protons flow back down their gradient via ATP synthase, which is built into the membrane nearby. The ATP synthase harnesses the proton-motive force to phosphorylate ADP, forming ATP. ... Why is the total count about 36 or 38 ATP molecules rather than a specific number?
How many ATP are produced in etc?
Electron transport chain
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 ATP are produced in TCA?
2 ATPs are produced in the TCA cycle per glucose molecule (2 acetyl CoA). ATP is produced when Succinyl CoA produces succinate by the enzyme succinyl CoA synthetase. It is important to note that most of the ATP produced in cellular respiration account for oxidative phosphorylation in the electron transport chain.
How many ATP molecules are produced in aerobic respiration How many ATP molecules are produced during fermentation and glycolysis?
In aerobic respiration, one molecule of glucose yields 38 ATP molecules, eight produced during glycolysis, six from the link reaction and 24 from the Krebs cycle. The net gain is 36 ATP, as two of the ATP molecules produced from glycolysis are used up in the re-oxidation of the hydrogen carrier molecule NAD.
How much ATP is produced by Nadph?
So, the correct answer is 3 ATP.
How many NADH are produced in cellular respiration?
net yield of 2 NADH per glucose (NADH is nicotine adenine dinucleotide, a co-enzyme that serves as a carrier for H+ ions liberated as glucose is oxidized.)
Why is the total count about 30 or 32?
Why is the total count of about 30 or 32 ATP molecules rather than a specific number? Organism that only carry out fermentation or anaerobic respiration, cannot survive in the presence of oxygen. Only creates two ATP for each molecule of glucose.
