Document Summary

Cartoons, figures and text produced by r turner/r edwards/l gieg unless otherwise indicated. In- class assignment #2 today! (wednesday october 8) Remember to print out and bring. Ve minutes, but then must work on your own to complete the assignment. Citric acid cycle made simple. From the cycle we get: (per acetyl- coa) Also, the carbons are converted to 2 co2. Summarize citric acid (aka krebs, tca) cycle: Acetyl- coa (from pyruvate) is turned into co2. Energy stored in atp (substrate- level phosphorylaoon) and reduced electron carriers (nadh and fadh2) Energy inventory so far (from 1 glucose molecule) Recall: where metabolic pathways occur (eukaryotes) Transports e- from nadh (or fadh2) to oxygen. Pumps h+ across the membrane proton moqve force. Complexes are on the inner mitochondrial membrane! Complex i transfers electrons & pumps h+ ions. Complex ii transfers electrons but does not pump h+ ions. Complex iii transfers electrons & pumps h+ ions.
