What is FA synthesized from?

• Acetyl CoA

• citrate

• malonyl

• oxaloacetate

Where is FA synthesized?

• Outer membrane

• Mitochondria matrix

• cytosol

• inner membrane

Where is most ACoA made?

• inner membrane

• mitochondrial matrix

• outer membrane

• cytosol

can acoa pass the inner mitochondrial membrane

• yes

• no

how does acoa get transported into the cytosol

• APL cleaves acoa to become smaller to pass the membrane

• its incorporated into citrate via the Krebs cycle (mitochondria) and transported with a citrate carrier

• AcoA is combined with CO2 to make malonyl to be launched out the imm

• it is added with oxaloacetate to leave the IMM
