Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
on an enzyme, the place that attaches to a substrate
A
Polypeptide
B
Base
C
Substrate
D
Active site
Explanation: 

Detailed explanation-1: -The part of the enzyme where the substrate binds is called the active site (since that’s where the catalytic “action” happens). A substrate enters the active site of the enzyme. This forms the enzyme-substrate complex.

Detailed explanation-2: -In biology and biochemistry, the active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction. The active site consists of amino acid residues that form temporary bonds with the substrate (binding site) and residues that catalyse a reaction of that substrate (catalytic site).

Detailed explanation-3: -The substrate reversibly binds to the active site of the enzyme, forming the enzyme-substrate (ES) complex. The bound substrate is converted to product by catalytic groups in the active site, forming the enzyme-product complex (EP).

Detailed explanation-4: -Enzymes bind substrates at key locations in their structure called active sites. They are typically highly specific and only bind certain substrates for certain reactions.

Detailed explanation-5: -Substrate bind to the active site of the enzyme through a variety of interactions. These forces are van der Waal, interactions, ionic bonding, hydrogen bonding or dipole-dipole interaction.
