Analyze Question 11

Enzymes are biological catalysts with highly specific three-dimensional shapes, particularly at their active sites. This unique conformation allows them to recognize and bind specifically to their corresponding reactant molecules, which are known as substrates.

Analyze Question 12

Enzymes are macromolecular biological catalysts. The vast majority of enzymes are composed of amino acid chains folded into complex three-dimensional structures, classifying them as proteins.
