Answer 2

The sequence of organic compounds during prolonged fasting:

• Option “B” is correct i.e. first carbohydrates, then fats and lastly protein.

• During prolonged fasting, the sequence of the organic compound used up by the body is carbohydrates-fats-protein.

• During prolonged fasting, the body experiences numerous biochemical and hormonal changes to make up for the lack of food. The glycogen and glucose kept in the body lasts for a short time. After these, the body transfers onto the adipose tissues or the fat stored in the body so that the store of vital proteins in the body gets safe or are utilized at last.
