BIOL 201 Lecture Notes - Lecture 26: Coenzyme Q – Cytochrome C Reductase, Facilitated Diffusion, Conformational Change
Document Summary
Summary: the flow of electrons and protons through the etc. Nadh, succinate & glycerol-3 phosphate (l3p) are the 3 main electron donors to the etc. Each can donate 2e-, but not all at the same time. Different donors donate to different initial complexes different #s of h + being passed across the imm when the e- are passed to o 2 (only 2e- can go through the etc at a time) Q is the e- collector collects 2e- at a time from a single initial complex at a time, and passes them to complex iii. Rotational force of the f 0 unit causes conformational change in the active site (f 1 ). It pushes against different catalytic subunits and move them around allows adp and p i to combine and form. Atp synthase uses energy stored in h + gradient formed by etc to drive atp synthesis.
