Exam preparation - Beta-oxidation
8 important questions on Exam preparation - Beta-oxidation
2 - ii) What is the starting input (reactant) for beta-oxidation?
2 - iv) What modification is required so that the fatty acid can be used to start beta-oxidation?
After a CA is attached to a FA, the compound is called an A CA
2 - iv) How is the fatty acid derivative moved into the mitochondria where beta-oxidation takes place? (3 parts)
The C T S is used to facilitate the movement of A CA into the M of the M
The M M is the location where B O occurs
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
2 - v) What purpose is the final output of beta-oxidation used for? (4 parts)
The C produces many E rich C E's that are taken to the E
The combination of the E and O P allow a lot of A to be made
The FA has converted into A
The E rich C E's produced in B O are taken to the E/O to generate A
2 - vi) Why is it necessary for us to perform beta-oxidation?
A CA are used to generate A via the C, E and O
3 - i) The third step (chemical reaction) of beta-oxidation is a redox reaction where the compound of the reaction is oxidised. How do the NAD+ and FAD coenzymes help facilitate these redox reactions in beta-oxidation? (3 parts)
N is R to N which allows the R to be O as the R loses T H A's
After losing T H A's the O forms a D C C B to the C to ensure both the C and the O have their C N of C B's
The O of the C converts the A F G to a K F G
3 - ii) Steps 2 of beta-oxidation is a hydration reaction. How does the addition of a single H2O results in the addition of an alcohol (-OH) group and the loss of a double carbon-carbon bond? (5 parts)
There are now T F B P's for other A's to attach to the C A's
H splits in T to become O and H
Each of the O and H attach to O of the C A's via a C B
The P C now contains an A A G as it has gained an O G
3 - iii) Step 4 of beta-oxidation is the thiolysis step that releases an acetyl CoA unit. What happens in the thiolysis reaction that allows an acetyl CoA to be released? (4 parts)
These T C's are attached to a CA and are an A CA
After an A CA is R from the FA, what remains of the FA attaches to another CA
The shorter FA will then re-enter another B O C
