electron transport chain Flashcards
What is the pH level is pure water
pH 7
What is pH?
Is the measure of the total hydrogen charge/ ion concentration in solution
What is responsible for ATP production?
Electron transport chain and ATP synthesis
NADH and FADH2 how many electrons
2
another name for electron transport chain
Respiratory chain, consists of large membrane protein complexes involved in electron transfers
where are proteins make up?
They are embedded in inner mitochondrial membrane
what is the final electron acceptor
O2
Where do NADH and FADH2 enter the respiratory (electron transport) chain?
NADH enters in complex 1 and FADH2 is complex 2
Which complexes use the energy from electron transfer to move protons?
Complex 1, 3 and 4
In which direction do the protons move through the protein complexes of the respiratory (electron transport) chain?
Mitochondria matrix to the intermembrane space
If the respiratory chain is working properly, how does the pH of the mitochondrial matrix differ from the pH in the intermembrane space (IMS)?
pH of mitochondria matrix will be higher than the intermembrane space
High ——- energy of NADH (electron donor) and O2 is low —— energy
Potential
The energy source that most directly drives ATP synthesis by ATP synthase during oxidative phosphorylation is the
H+ going down the concentration gradient
Which portion of ATP synthase catalyzes the formation of ATP from ADP and Pi?
F1
ATP production by the transfer of phosphate from substrate directly to ADP is called
substrate level phosphorylation
