Lipids Metabolism (FA oxidation)

Question 1

Catabolism of fatty acids

Answer 1

• Occurred at mitochondria
• Produce acetyl-CoA
• NADH & FADH2 is the reducing power

Question 2

Anabolism of fatty acids

Answer 2

• Occurred at animal cytosol and plant chloroplast
• Start as a condensation of malonyl-CoA and acetyl-CoA
• NADPH is the reducing power

Question 3

Fatty acid Oxidation

Answer 3

3 types (B , A , W)

Question 4

Beta oxidation

Answer 4

Major pathway → mitochondria

Produce acetyl & propinoyl co A

Successive removal of 2 carbon atoms (acetyl co A).

Question 5

Alpha oxidation

Answer 5

Alternative (brain) minor path way

Question 6

Omega oxidation

Answer 6

ER, Succinvl COA

Question 7

Minor & major oxidation pathways

Answer 7

eliminate toxic level FA

Question 8

Beta oxidation pri steps

Answer 8

Activation & transportation

Question 9

Beta oxidation Occurs in .. steps

Answer 9

4
oxidation - Hydration - oxidation - Splitting

Question 10

Complete Beta oxidation

Answer 10

a- formation acetyl coA & NADH & FADH2
B- oxidation acetyl co A …TCA cycle to CO2 & H2O
