Question 1
1 / -0

Substrates bind to the active sites of an enzyme by interactions like :

A
ionic bonding

B
hydrogen bonding

C
van Der Waals' interactions

D
All of the above

Solution

Substrates bind to the active site of the enzyme through hydrogen bonds, hydrophobic interactions, ionic bonding, temporary covalent interactions (Van der Waals') or a combination of all of these to form the enzyme-substrate complex.
Question 2
1 / -0

Drugs which supplement (or) substitute for chemical messengers are :

A
antagonists

B
agonists

C
blocking chemicals

D
all

Solution

An agonist is a chemical that binds to some receptor of a cell and triggers a response by that cell. Agonists often mimic the action of a naturally occurring substance.
Whereas an agonist causes an action, an antagonist blocks the action of the agonist and an inverse agonist causes an action opposite to that of the agonist. So agonist drugs copy the action of the chemical messengers thereby substituting them.
