Describe the electron transport chain and why the electrons are passed only one direction from one transport protein to another.
Homework Answers
Electron transport chain is the major component of respiratory system. Electrons from NAD and FAD passes through complex I to complex IV and the level of energy is decreased as the electrons passes from complex 1 to 4. Since the next level of energy is less than the previous one, energy releases at each step and released energy is used to pump the hydrogen ions from inner mitochondrial matrix to intermitochondrial membranous space which is essential for ATP synthesis.

What happens along an electron transport chain?
What happens along an electron transport chain? Electrons are passed from a reducing agent to an oxidizing agent, releasing free energy at each step. Electrons are passed from molecule to molecule, gaining potential energy at each step. O Electrons store energy that can be used to break down sugar molecules. O Protons are pumped through ATP synthase, making ATP.

Describe the oxidation-reduction that the components of the electron transport chain undergo as electrons are accepted and donated. Include in your answer the direction of electronegativity as well as the separate roles of the components of the electron transport chain including flavin mononucleotide, the Fe-S group, ubiquinone, and the cytochromes.

It is used to phosphorylate NAD+ to NADPH B. It excites electrons of the reaction center of photosystem I. C. It is used to maintain a proton gradient for ATP synthesis D. It is used to break down a water molecule

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...
