Document Summary

Respiration: passing e-s down an etc and reducing an exogenous e- acceptor. For almost all euk, tea is o2. Many bacteria can use alt e- acceptors, which allows them to do anaerobic. Complex i-iv: know that there"s 4, can order by reduction potential. I : e-s from nadh, flavoprotein and fe-s proteins, 4 h+ out (generates pmf) Chemoorganotrophs obt e-s from c sources using nadh as carrier, their etc starts w/ complex i, which gets e-s from nadh. Ii: enter via succinate and fadh2, e-s enter quinone cycle, passed to iii 4. When quinone receives e-s from upstream carrier (like fe/s), it also needs h+ to become fully reduced, therefore it accepts from cytoplasm. When quinone donates e-s to a downstream carrier, h+ are released into the periplasm and help gen pmf. E-s can also be shuttled btw large complexes by mobile proteins like cyt c. Iv : h+ and o2 to water, 2 h+ out.
