Enzymes only work with certain substrates. If a certain enzyme only works with a certain substrate, it is because the enzyme Group of answer choices has a particular shape that matches the substrate. can only reach that one substrate inside the cell. activates in response to chemicals from the substrate. is only found in organisms with that substrate.

has a particular shape that matches the substrate

Explanation:

Enzymes are proteinous biological catalyst i.e. they speed up the rate of biochemical reactions in living systems. Like every other catalyst, enzymes reduce the activation energy of the reactions they are involved in without getting used up in the process.

Enzymes operate by binding to a substrate molecule i.e. the reactant and form a bond with them in order to synthesize a product. However, enzymes are substrate-specific i.e. they are very particular about the substrate they bind to. This property is due to the shape of the enzyme which matches a particular substrate.

Enzymes, like every other protein molecules, are made up of amino acid subunits, which are responsible for the shape that determines the specificity of the protein.
