How much ATP does aerobic respiration make total?

How much ATP does aerobic respiration make total?

The three stages of aerobic cellular respiration are glycolysis (an anaerobic process), the Krebs cycle, and oxidative phosphorylation….Aerobic vs anaerobic respiration.

Aerobic Anaerobic
ATP produced Large amount (36 ATP) Small amount (2 ATP)

Does aerobic 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.

Is it 36 or 38 ATP?

ATP yield during aerobic respiration is not 36–38, but only about 30–32 ATP molecules / 1 molecule of glucose .

Why do we use 36 ATP instead of 38?

If you use the phosphero-glycerol shuttle you get 36 ATP (trades cytoplasmic NADH for mitochondrial FADH2). NADH yields ~ 3 ATP thats why you get 38 if you use the malate shuttle. FADH2 yields ~ 2 ATP thats why you get 36 if you use the phosphero-glycerol shuttle.

What is the net gain of ATP in aerobic respiration?

There is net gain of 38 ATP molecules during aerobic respiration of one molecule of glucose. But in most eukaryotic cells, 2 molecules of ATP are required for transporting the NADH produced in glycolysis into the mitochondrion for further oxidation.

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.

What is the net gain of ATP in glycolysis?

2
In glycolysis, the net gain of ATP molecules is 2. Two ATP per glucose molecule are required to initiate the process, then a total of four ATP are produced per molecule of glucose.

What is the net gain of ATP?

There is net gain of 38 ATP molecules during aerobic respiration of one molecule of glucose. But in most eukaryotic cells, 2 molecules of ATP are required for transporting the NADH produced in glycolysis into the mitochondrion for further oxidation. Hence, net gain of ATP here is 36 molecules.

How many net ATP is produced in glycolysis?

two ATP molecules
Overall, glycolysis produces two pyruvate molecules, a net gain of two ATP molecules, and two NADH molecules.

How much ATP is produced by cellular respiration?

Most of the ATP produced by aerobic cellular respiration is made by oxidative phosphorylation. 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 ATP molecules are produced during chemiosmosis?

My biochemistry text (which is recent) says that chemiosmosis produces about 28 ATP per starting glucose. Adding that to the 2 net ATP from glycolysis and the 2 ATP from the tricarboxlyic acid cycle (a.k.a. the Kreb’s cycle) comes t Aerobic respiration produces a net yield of about 32 ATP per starting glucose.

What is the net yield of aerobic respiration?

Aerobic respiration produces a net yield of about 32 ATP per starting glucose. The final stages of aerobic respiration are not just chemical reactions, where we can balance chemical equations and get exact numbers for products.

How many ATP molecules are produced per starting mole of glucose?

About 30 moles of ATP are produced per starting mole of glucose. Cellular respiration can be broken down into 5 steps, and all of them – except for the first one – occur inside mitochondria. 1. Glycolysis
