Why is the 'active site' of an enzyme important?
A
It is the area that allows the enzyme to be transported within the cell.
B
It is the part of the enzyme that is responsible for its stability.
C
It is where the substrate binds and the reaction is catalyzed.
D
It is the region that determines the enzyme's solubility in water.
Verified step by step guidance1
Understand that enzymes are biological catalysts that speed up chemical reactions in the body without being consumed in the process.
Recognize that the 'active site' of an enzyme is a specific region where the substrate molecules bind. This is crucial for the enzyme's function.
The active site is typically a pocket or groove on the enzyme's surface, formed by the unique three-dimensional structure of the enzyme.
When a substrate binds to the active site, it forms an enzyme-substrate complex. This binding can induce a change in the enzyme's shape, facilitating the chemical reaction.
The active site is essential because it lowers the activation energy of the reaction, allowing the reaction to proceed more quickly and efficiently.
