Answer 1

i) What are the electron carrier molecules at the beginning of the chain NADH/FADH2

ii) In what order are the components of the chain arranged increasing electronegativity

iii)What is created by the ETC in the intermembrane space electrochemical gradient

iv) What accepsts the electrons at the and of the chain oxygen

v) Where does NADH get oxidized NADH dehydrogenase

vi) What complex catalyzes the reaction that produces water decreasing eletronegativity

vii) What provides the energy to make ATP protons (H+)

viii) What is made in the process of chemiosmosis ATP
