What is the direct energy source that drives ATP synthesis during respiratory oxidative phosphorylation?
The difference in H+ concentrations on opposite sides of the inner mitochondrial membrane.
During oxidative phosphorylation, NADH and FADH oxidizes at the hydrogen carriers to provide electrons to the electron transport chain (etc) (chain of electron carriers) and H+ ions. As electrons pass through the etc, ATP is synthesized.
If energy is ever needed along the process, ATP is used. But i doubt it as the electron do not require external chemical energy to move along the carriers.
What else can I help you with?
In fermentation is ATP produced by substrate level phosphorylation or oxidative phosphorylation or both or neither?
ATP in fermentation is typically produced by substrate-level phosphorylation, which involves the direct transfer of a phosphate group to ADP from a phosphorylated substrate. Oxidative phosphorylation, which involves the use of an electron transport chain to produce ATP, is not generally involved in fermentation.
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.
Substrate-level phosphorylation can best be describe as?
Substrate-level phosphorylation can best be describe as the direct transfer of phosphate from one substrate to another. Oxidative phosphorylation is different from substrate level phosphorylation is that it generates ATP by using a proton motive force.
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.
The production of energy-rich ATP molecules is the direct result of?
The production of energy-rich ATP molecules is the direct result of cellular respiration, specifically the process of oxidative phosphorylation. During this process, high-energy electrons from the breakdown of food molecules are used to create a proton gradient across the inner mitochondrial membrane, which drives the synthesis of ATP by ATP synthase.
What is the direct energy source that drives ATP synthesis during respiratory oxidative phosphorylation in eukaryotic cells?
the proton-motive force across the inner mitochondrial membrane.

The direct source of ATP for the development of a fetus is?
The direct source of ATP for the development of a fetus is glucose. Glucose is obtained from the mother through the placenta and is used by the fetus for energy production through glycolysis and oxidative phosphorylation in the mitochondria of fetal cells.
ATP can convert to ADP during what?
Phosphorylation. It can be done by direct transfer of phosphate group (substrate-level phosphorylation), by the use of proton gradient (oxidative phosphorylation), or by using sunlight (photophosphorylation).

What structure of the throat opens to direct air into the respiratory pathway?
The epiglottis opens to direct air into the respiratory pathway.
The transfer of a phosphate group that occurs in glycolysis is called?
The transfer of a phosphate group that occurs in glycolysis is called substrate-level phosphorylation. This process involves the direct transfer of a phosphate group from a substrate molecule to ADP to form ATP.

What is the difference between direct combination synthesis reaction?
A direct combination reaction is when two or more reactants combine to form a single product, without the need for a catalyst or additional reactants. Synthesis reactions involve the formation of a new compound from simpler reactants. So, direct combination synthesis is a specific type of synthesis reaction where the products are formed directly from elements or simpler compounds without any side products.
What is subtrate level phosphorylation?
Oxidation of G3P occurs by the removal of hydrogen atoms are picked up by NAD+, and NADH+H+ results. Later the NADH will pass on electrons to the electron transport chain. Oxidation of G3P and subsequent substrtes result in four high energy phosphate groups and these are used to synthesize four ATP. So basically substrate-level ATP synthesis is when an enzyme passes a high-energy phosphate to ADP and ATP results.
