which electron carrier brings electrons to the electron transport chain via complex I
answer NADH
===========================
which electron carrier brings electrons to the electron transport chain via complex I1
answer =FADH2 ;FAD
===========================
As electron transport chain proceeds H ions (protons) are pumped from the mitochondrial matrix into the intermembrane space
===========================
explanation
Complex II
In Complex two electrons are expelled from NADH and exchanged to a lipid-solvent transporter, ubiquinone (Q). The decreased item, ubiquinol (QH2), unreservedly diffuses inside the layer, and Complex I translocates four protons (H+) over the film, along these lines delivering a proton inclination. Complex I is one of the primary destinations at which untimely electron spillage to oxygen happens, along these lines being one of the fundamental locales of creation of superoxide
Complex II
The extra electrons are conveyed into the quinone pool (Q) starting from succinate and exchanged through flavin adenine dinucleotide (FAD)) to Q. It comprises of four protein subunits such as succinate dehydrogenase, ,succinate dehydrogenase iron-sulfur subunit, mitochondrial,

9. In the electron transport chain picture above, how do electrons move from protein complex I to protein complex II? 1. I need you to remember that "Q" is ubiquinone which gets reduced at proteins l & I, and oxidized at protein III. "Reduced" means gains electrons, "oxidized" means loses electrons. 2. I need you to remember how "Q" moves from protein I to protein Do you remember? Don't overthink it, Preeda. As far as scientists know right now, the...

Cellular respiration: The Electron Transport Chain The breakdown of glucose ends during the Krebs cydle; however, it is important to note that the energy previously contained in glucose is mostly stored in NADH and FADHz. In the last step of celular respiration, the high-energy electrons within NADH and FADH2 are passed within a set of proteins found in the inner membrane of the mitochondrion, collectively known as the electron transport chain. The electrons provide the energy to create ATP, which...
