Question

multiple - choice question
when properly aligned, the enzyme and substrate form
a phosphorylated intermediate
a product.
a cofactor
an enzyme - substrate complex.
a coenzyme

Explanation:

Enzymes are biological catalysts. When an enzyme and its specific substrate are properly aligned, they first form an enzyme - substrate complex. This complex is a temporary structure that allows the chemical reaction to occur more efficiently. A phosphorylated intermediate is related to phosphorylation reactions, a product is the result of the reaction after the complex breaks down, a cofactor is a non - protein component that helps the enzyme function, and a coenzyme is a type of cofactor that is an organic molecule.

Answer:

D. an enzyme - substrate complex.
