Did a bit of research, found a cool one.
Did you know that our brains are split into two parts, right inside our head? One half is the left brain and the other half is the right brain. Some people use one half of the brain more than the other half when they are doing certain activities, like talking or reading. The half that is used is sometimes tied to which hand they prefer to use. If someone likes to use their right hand when doing an activity, like drawing or throwing a ball, do they also prefer to use their right ear, eye, or foot when hearing, seeing, or kicking something? Which side do people use the most? In this science project, you will get to find out!

Answer:
Hi!
The answer is (C) Both (a) and (b)
Explanation:
Drug Metabolism:
- Drug metabolism is divided into two steps: Phase 1 and Phase 2 reactions.
- Phase 1 reactions involve the degradation or formation of functional groups.
- Phase 2 reactions involve the conjugation of the drug or its Phase 1 intermediate with a polar conjugating molecule. Phase 2 generally performs the detoxification step in the drug degradation process.
- Phase 2 or conjugation reactions are further divided into 2 types:
- Type 1: Glucoronidation and sulfonation: An activated conjugating molecule such as glucoronic acid, sulfate or glutathione etc. is combined with the drug to form a conjugated molecule.
- Type 2: Amino acid conjugation: An activated drug or substrate is conjugated with an amino acid such as glycine or glutamine.
Glutathione Conjugation:
Glutathione is a tripeptide found in most tissues, particularly in the liver. It performs important detoxification functions for all cells. The enzyme, glutathione S-transferase conjugates glutathione with drug intermediates to form a drug-glutathione conjugate. This conjugate can easily be excreted through bile or urine.
Amino acid Conjugation:
This is an important reaction in xenobiotic biotransformation; particularly for xenobiotics with carboxylic group or an aromatic hydroxylamine groups. Drug intermediates combine with glycine or glutamine to form an amino acid conjugate.
