During prolonged fasting, the body undergoes several biochemical and hormonal changes to make up for the lack of food and hence energy so as to be able to continue the vital processes needed for existence. The glycogen and glucose stored in the body last for a short time. After these, the body moves onto the adipose tissues or the fat accumulated in the body so that the store of vital proteins in the body gets spared or is utilized at last.
So, the correct answer is 'First carbohydrates, next fats and lastly proteins'.
So, the correct answer is 'First carbohydrates, next fats and lastly proteins'.

Explanation:
The correct answer is option 'A': During prolonged fasting, the sequence in which organic compounds are used up by the body is carbohydrates first, followed by fats, and lastly proteins.
Reasoning:
During fasting, the body goes into a state of energy conservation and begins to utilize stored energy sources to meet its energy demands. The body primarily relies on carbohydrates for energy, which are stored in the form of glycogen in the liver and muscles.
Sequence of Organic Compound Utilization:
- Carbohydrates: Initially, the body depletes its glycogen stores through a process called glycogenolysis. This provides an immediate source of energy.
- Fats: Once the glycogen stores are depleted, the body switches to utilizing fats as the primary fuel source. Fats are broken down into fatty acids and glycerol through a process called lipolysis. The fatty acids are then converted into molecules called ketone bodies, which are used as an alternative energy source by tissues, including the brain.
- Proteins: In the absence of sufficient carbohydrates and fats, the body starts breaking down proteins. Proteins are primarily used for building and repairing tissues but can be broken down into amino acids to provide energy. However, breaking down proteins for energy is not ideal as it can lead to muscle wasting and other negative health effects.
Conclusion:
During prolonged fasting, the body utilizes organic compounds in the following sequence: carbohydrates first, followed by fats, and lastly proteins. This sequence ensures that the body conserves its energy stores and prioritizes the use of carbohydrates and fats before resorting to breaking down proteins for energy.
