Unformatted text preview: 14_21_Redox_potential .jpg • The proton gradient drives ATP Synthesis. • ATP synthase complex is in the inner mitochondrial membrane. It is composed of three subunits: – F o the intermembranous H+ channel – Stalk – F 1 is the ATPase complex • As the F1 complex rotates through its open, loose, and tight configurations, ATP is synthesized from ADP + Pi. • The necessary energy comes from dissipation of proton gradient. 14_14_ATPsynthase1.jpg 14_15_ATPsynthase2.jpg 14_27_H_pump_change.jpg 14_16_coupled_transpor.jpg...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
