What is the main job of the electron carriers in cellular respiration? 

• Transport electrons and hydrogen atoms to the electron transport chain 

• Capture energy throughout the process of cellular respiration

• Provide the reactants for the process of cellular respiration

During chemiosmosis

• H+ ions serve as the final electron acceptor

• a concentration gradient is generated when H+ ions are passively transported from the matrix to the intermembrane space of the mitochondrion

• energy is released as H+ ions move freely across the mitochondrial membrane

• ATP is synthesized when H+ ions move through a channel in ATP synthase

Which of the following structure is where cellular respiration (Kreb's Cycle and Electron Transport Chain) occurs in the cell?

• nucleus

• cytoplasm

• mitochondria

• vacuoles

•   Brownian motion of the protons.

•   peer pressure of the cool electrons in the stroma.  

• movement of electrons through the electron transport chain
