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.

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 a copy of DNA that is used to direct the synthesis of a specific protein?
A gene is a segment of DNA that is used to direct the synthesis of a specific protein.
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.
Muscles produce ATP by what pathways?
Actually, there are 3 pathways for creating ATP for muscle contraction. 1) Direct phosphorylation of ADP by creatine phosphate, 2) aerobic respiration and 3) anaerobic glycolysis & lactic acid formation.
Protein synthesis occurs in the ribosomes or nuclear envelope?
Protein synthesis occurs along the ribosome. The nuclear membrane doesn't have any direct influence in making proteins.
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.
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.
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.

What is the difference between direct combination synthesis reaction?
they are the same thing
A chemical reaction in which two elements combine to form a compound is called a?
synthesis reaction
Enzymes are produced as a direct result of which process?
1)protein synthesis 2)photosynthesis 3)respiration 4)enzymatic hydrolysis
What is used to direct protein synthesis in a cell?
Ribosomes are the 'work stations' that direct that production of proteins. It used mRNA as a blue print.
