Role and characteristics of the heme group heme

15.?Role and characteristics of the heme group
- Heme groups: All 3 have a Fe+3(ferric form) in the middle, can only
accept 1 electron at a time. (CONFIRM IN VIDEO)
16.
- --?Major features of the Q cycle (slide 22)
-2 rounds.
- Qh2= donating electrons will be re-oxidized to Q by releasing 2 electrons.
ROUND 1: 1 e- to cytc b and transfers to Q and releases 2H+. 1 e- is
accepted by cytc c(Fe 3+)
Round 2: same mechanism but the difference is incoming 2H+, H2
accepts 2H+ from the matix side
17.Function of complex III

- Also tranport e-’s and protons
- NET translocation is 2 protons
- 4 H+ are pumped out
-
Complex III- contains cytochrome proteins (complex 3, 3=c, cytochrome
proteins)
18.Function of cytochrome c
19.Function of complex IV 20.Description of the chemiosmotic theory
21.?Structural characteristics of ATP synthase Function of ATP synthase 22.Mechanism of H+ transport by ATP synthase 23.The binding change mechanism of ATP synthase
