ETC

Question 1

ETC

where is the ETC?

Answer 1

-mitochondrial membrane

Question 2

ETC

5 major components?

Answer 2

• NADH dehydrogenase
• succinate dehydrogenase
• cytochrome BC1 complex
• cytochrome oxidase
• oxygen

Question 3

ETC

mobile electron carries?

Answer 3

• 2
• UQ
• Cyt C

Question 4

ETC

step 1?

Answer 4

• proteins set up in increasing electronegativity
• first component, weak electron acceptor
• last component, strong electron acceptor

Question 5

ETC

step 2?

Answer 5

• electrons passed along components along membrane
• NADH binds to NADH dehydrogenase
• FADH2 binds to succinate dehydrogenase(2nd component)
• H+ pumped into inter membrane space
• UQ carries electrons from NADH dehydrogenase to BC1
• Cyt C carries electrons from BC1 to cytochrome oxidase

Question 6

ETC
important terms:
Chemiosmosis? 
Mobile electron carrier?
Electron carriers?

Answer 6

• production of ATP
• movement of ions from high concentration to low concentration through membrane protein
• results in release of hydrogen
• carry electrons between proteins in inner membrane of mitochondria
• UQ and Cyt C, carry electrons they receive through oxidation of glucose
