12.3 oxidative phosphorylation

Question 1

where does oxidative phosphorylation occur?

Answer 1

inner mitochondrial membrane (cristae)

Question 2

respiration of lipids

Answer 2

• lipids -> glycerol + fatty acids
• glycerol + Pi -> triose phosphate
• enters glycolysis
• fatty acid -> 2 C -> acetyl CoA
• enters krebs

Question 3

respiration of proteins

Answer 3

• proteins -> amino acids
• deamination (amine group removed)
• enter at different points

Question 4

electron transfer chain

Answer 4

• NADH and FADH donate electrons
• goes down ETC
• energy released
• used to actively transport H+ into intermembranel space from inner membrane
• H+ move down [H+] gradient through ATP synthase channels
