What does NADPH add to the Calvin cycle?
NADH is generated by the electrons transferred to the NAD+. It is used in oxidative phosphorylation of for ATP synthesis later on.
What is equation for oxidative phosphorylation?
3ADP + 3Pi + NADH + H+ +1/2O2 ----> 3ATP +NAD+ + H20
Products of oxidative phosphorylation?
ATP is created by the movement of protons back into the mitochondrial matrix through complex V which is ATP synthase. The effect that electron transport has on oxidative phosphorylation is that the two processes are tightly coupled, stopping electron transport will ultimately stop oxidative phosphorylation.
When NADH loses a hydrogen ion?
It becomes NAD. This happens during electron transport where NADH drops off its H+ and electrons to be used in oxidative phosphorylation. NAD now must move to glycolysis or citric acid cycle to regain its hydrogen.
What is the function of dehydrogenase?
dehydrogenase is an enzyme which transfers hydrogen ions from a substrate to an activator.Example are activators are NAD+ and FAD+.
What is an output from oxidative phosphorylation?
Net inputs: glucose, ADP, NAD+ Net outputs: Pyruvate, NADH, ATP
What does fermentation replenish?
Answer: NAD+. Glycolysis requires a constant supplies of NAD+, which is used to produce NADH. In oxidative phosphorylation, the electron transfer chain will reduce the NADH to NAD+. Fermentation does the same task but in a slower fashion. NAD+ is essential for glycolysis.
Photophosphorylation differs from oxidative phosphorylation in that?
in oxidative phosphorylation, the H+ moved out of the cell using the channel proteins that make up the ETC (electron transport chain) and then they flow back into the mitochondria through the ATP synthase because of the concentration gradient. Photophosphorylation has its H+ ions travelling in the opposite direction (from inside to outside of the chloroplasts through ATP synthase. Another difference is the fact that in photophosphorylation the H+ are produced by splitting water while the H+ in oxidative phosporylation come from H+ that have been removed from compounds and have had their electrons removed by NAD+ or FAD.
Why NAD plus can be used to shuttle electrons?
NAD+ accept electrons.
What is the role of enzyme complex in the electron transport chain?
A. Transfer electrons to NAD+ B. Power Krebs cycle C. Receive electrons from NADH D. Produce ATP from sugar
Where does the oxygen in the electron transport chain comes from?
The high energy electrons come from NADH and FADH2 (as they are electron carriers). NADH is produced throughout various stages of cellular respiration (aerobic respiration), while FADH2 is produced mainly as a product of the Kreb's cycle.
Where is most of the ATP made in cellular respiration?
The most ATP is created when NADH+ is reduced in the electron transport chain to NAD which causes a proton gradient that is then pumped through ATP synthase (and enzyme) creating most of the ATP in Cellular Resp.
