Question 1

Where is fatty acid broken down

Answer 1

Mitochondria

Question 2

Degradation of fatty acid simple schematic

Answer 2

Oxidation then hydration then oxidation then cleavage

Synthesis opposite

Question 3

Degradation of fatty acids

Answer 3

Oxidative process - B oxidation

1. Oxidation - Introduced double bound using a dehydrogenase and FAD
2. Double hydrated by a hydrotase introducing an OH
3. Hydroxyl is oxidised to a ketone using a dehydrogenase and NAD+
4. Fatty acid cleavage to give Acetyl CoA using a thiolase

Question 4

Absorption synthesis and storage

Answer 4

.

Question 5

What must fatty acids become before entering the mitochondria

Answer 5

must be activated through the formation of a thioester linkage to co-enzyme A

takes place in outer mitochondrial membrane

Question 6

Ketone bodies

Answer 6

Are formed from acetyl CoA when fat breakdown predominates in liver
