BERG/STRYER VI STUDY GUIDE CHAPTER 18 1. Homework 1-4, 8, 10. Understand the overview (502-5). This chapter is about energetics in the mitochondrion , but mitochondria are symbiotic bacteria, and parallel processes are found everywhere in prokaryotic cells. Electron transport directly produces a proton gradient . The protons flow back in through the mitochondrial inner membrane , driving protein-based machinery, which causes ATP to be synthesized. The electrons come from NADH and FADH 2 in the matrix , and the ATP is also formed in the matrix. You should be able to calculate the standard free energy change given half reaction potentials (Table 18.1) using the equation Δ G o ' = –nF Δ E o ' (507). Electrons move from higher energy (top of the table) to lower energy in the electron transport chain (ETC). You should be able to write out the components of the ETC and divide them into the four complexes. Learn this linear version: NADH, FMN, (FeS) n , Q, b L , b H , FeS, c 1 , c, Cu A , a, a 3 , Cu B , O 2 .
