The location on an enzyme where a substrate binds is called the:

Explanation

Option A: Binding site typically also refers to the active site, but active site is the better answer for the question. Option B:The reaction center present in the leaves contains pigments such as chlorophyll. These absorb light, promoting an electron to a higher energy level producing ATP through the electron transport chain. Option C: The allosteric site is a site on an enzyme where a molecule that is not a substrate may bind, thus changing the shape of the enzyme and influencing its ability to be active. Option D: In the lock and Key Model, the lock is the enzyme and the key is the substrate.This model states that both enzyme and substrate are rigid structures and only the correctly sized key (substrate) fits into the keyhole (active site) Option E: The part of the enzyme where the substrate binds is called the active site. This forms the enzyme-substrate complex.This option is preferred over Option A because it is more commonly used in the textbook.
