Which of these is the second step of an enzymatic reaction?(a) Binding

1.	Which of these is the second step of an enzymatic reaction?(a) Binding of the substrate to the enzyme(b) Change in the conformation of the enzyme(c) Production of an enzyme-substrate complex(d) Release of product from the enzymeI got this question in an online quiz.Question is taken from Biomolecules in portion Biomolecules of Biology – Class 11
Answer» Right option is (a) Binding of the SUBSTRATE to the enzyme For explanation I would say: In an enzymatic reaction, a substrate FIRST binds to the active site of an enzyme. This INDUCES a conformational change in the enzyme to form an enzyme-substrate COMPLEX. This is converted into a product which is then released.
