Electron Transport Chain

Question 1

What is the purpose of the electron transport chain

Answer 1

Occurs in mitochondrial matrix
Transports e- across the matrix to open proton spores and be eventually converted into water
Pumps H+ out of the matrix and creates ATP

Question 2

How many complexes are there

Answer 2

4

Question 3

Which complexes have proton spores

Answer 3

Complex 1,3, 4

Question 4

Which complex makes water and how

Answer 4

Complex 4, using e- & 2H+ + 1/2 O2

Question 5

Explain the conc. gradient at the end

Answer 5

High H+ outside the matrix (in the inter membrane space), low conc. H+ inside the matrix membrane

Question 6

Explain ATP synthase

Answer 6

Creates ATP by absorbing potential energy as it spins from transporting H+ from high conc. to low conc. in the matrix membrane through oxidative phosphorylation

Question 7

How much ATP is generated

Answer 7

1NADH=3ATP
1FADH2= 2ATP
Overall= 5

Question 8

Which enzyme excepts e- from complex 1/2

Answer 8

Co enzyme Q10 ( ubiquinone)

Question 9

Which enzyme is an intermediate between complex 3/4

Answer 9

Cyt. C
