What is the name of the site where the substrate binds to the enzyme?

The answer is : "The Active Site"

Explanation:

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.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
