Arrange the following events in the correct order.
a) an enzyme/substrate complex is formed.
b) products leave the active site of the enzyme.
c) a substrate is converted to products and enzyme/products complex is formed.
d) a substrate enters the active site of the enzyme.

D, A, C, B.

Explanation: The enzymatic reaction first requires that the enzyme recognizes its substrate and enters in the enzyme's active site. Then enzyme and the substrate form a complex called enzyme/substrate complex and the substrate is converted to products in the complex and then release from the active site, so the enzyme can bond to another substrate molecule.

explanation:

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
