Answer :
The subject of this question is glucuronic acid conjugation, which is a biochemical process that occurs in the human body. Let's go through each option to find the exception:
It is an important pathway in the newborn.
- Glucuronic acid conjugation is indeed an important metabolic pathway in newborns. This pathway helps in the detoxification and elimination of drugs and other substances.
After conjugation, it usually leads to inactivation of drug.
- Yes, glucuronic acid conjugation typically results in the inactivation of drugs. The conjugation process makes the drugs more water-soluble, allowing for easier excretion from the body.
In the human body, the glucuronic acid conjugation is predominant.
- This statement is correct. Glucuronic acid conjugation is one of the major pathways for phase II metabolism in the human liver, aiding in the detoxification of numerous substances.
None of the answers.
- This option implies that each of the initial statements is true.
Two of the answers.
- This option would imply that two of the statements given are exceptions, which is not correct based on what we have evaluated.
Considering the above explanations, all the listed statements about glucuronic acid conjugation are true. Therefore, the correct choice is:
d. None of the answers.
In summary, glucuronic acid conjugation is indeed crucial across various stages of human development, primarily inactivates drugs for excretion, and is a predominant detoxification pathway in the human body.
