Why does the ATP formed during the oxidative phosphorylation phase of cellular respiration vary between 32 and 34 ATP?

Hi, this is because it depends on which electron transporter from the Krebs cycle, NADH or FADH2 delivers electrons to the electron transport chain. Each NADH will generate 3 ATP in the electron transport chain while FADH2 will only deliver 2 ATP per molecule. This is so because FADH2 drops off the electrons in the mitochondria at a lower energy level (they enter later in the chain) than do NADH. Hope this helps.

∙ 11y agoThe energy produced by NADPH ranges from 2.5 to 3.3 ATP, and FADH2 from 1.5 ATP to 2 ATP. This range along with not all of the protons flowing through the ATP synthase accounts for this discrepancy. That is why there is not an exact number.

Differentiate between external inertial cellular respiration?
The external inertial respiration refers to breathing, while the cellular respiration refers to respiration between the cells.
What is one true distinction between fermentation and cellular respiration?
cellular respiration uses oxygen but fermentation does not use oxygen
What is external respiration and internal respiration?
External respiration is to breathe and facilitate gas exchange in the lungs or an analogous body cavity, depending on the organisms anatomy. Cellular respiration is the process of oxidative phosphorylation, where ATP energy is generated from biomolecules by the cell. In aerobes, the process involves a series of electron steps and oxygen is the terminal electron acceptor
What is the main relationship between photosynthesis and cellular respiration?
The products of photosynthesis are used in the process of cellular respiration and vice versa.
What is the major similarity and difference between cellular respiration and respiration and photosynthesis?
That it have cell
What is oxidative phosphorylation and what is its purpose?
Oxidative phosphorylation occurs in order to produce energy in the form of ATP. It occurs after chemiosmosis, in which a concentration gradient of hydrogen ions is created in the mitochondria between the matrix and the intermembrane space. As the hydrogen ions flow across this gradient, ADP and Pi are combined and ATP is produced. Hope this helps!
What is the difference between photorespiration and respiration?
photorespiration: RuBP accepts oxygen instead of CO2 during photosynthesis because production of oxygen has exceeded production of CO2. respiration: Oxygen is produced in oxidative phosphorylation/chemisosmosis and used to produce water during respiration.
Different between oxidative phosphorylation and substrate level phosphorylation?
Substrate-level phosphorylation occurs during Glycolysis and the Kreb's Cycle and involves the physical addition of a free phosphate to ADP to form ATP. Oxidative phosphorylation, on the other hand, takes place along the electron transport chain, where ATP is synthesized indirectly from the creation of a proton gradient and the movement of these protons back accross the membrane through the protein channel, ATP synthase. As the protons pass through, ATP is created.

What is the process of converting energycfrom a light -excited electron into pyrophosphate bond of an ADP molecule?
Most probably it is the substrate-level phosphorylation.
What is released when a chemical bond is broken between the second and third phosphate of an ATP molecule?
It isn't. AMP (adenosine monophosphate) remains intact but has no chemical energy to give and it is not broken off. It must be reenergized in the portion of cellular respiration called oxidative phosphorylation, where it goes to ADP (a-diphosphate) and finally to ATP (a-triphosphate), which is as high as the molecule can go and remain stable.
What is the difference between substrate level phosphorylation and chemiosmosis?
substrate level phosphorylation does not involve (electron transport chain), oxidative phosphorylation does. Substrate level phosphorylation involves the direct transfer of phosphate from a phosphate bearing molecule to ADP, thus yielding ATP. In cellular respiration, oxidative phosphorylation requires a protein, ATP synthase, to channel energy provided by a concentration of H ions; this energy results in the combining of phosphate with ADP.
