Question

Which of the following pathways would increase its activity level during starvation?

• A. Fatty acid degradation
• B. Amino acid synthesis
• C. Fatty acid synthesis
• D. None of these

Answer 1

The correct option is A Fatty acid degradation

• During starvation the priority of the metabolism in body is to provide sufficeint glucose to the brain and other tissues that are absolutely dependent on this fuel,.
• However precursors of the glucose are not abundant at the time of starvation and most of the stored fatty acid is utilised at times like this.
• These fatty acid cannot be converted to glucose because acetyl CoA cannot be transformed to pyruvate.
• Therefore the fatty acid that are stored in the body are converted to acetyl CoA and are used in the metabolism to provide energy to the body in the state of starvation.
• Therefore the answer option 'Fatty acid degradation' is correct.
