Which statement best summarizes what you have learned about substrate and enzyme binding and how it affects the function of enzymes?

a) The shape of enzymes changes slightly as they interact with the substrate, creating a lock-and-key fit.
b) The changing of the shape of the substrate can slow down reactions by preventing the binding of the substrate and the active site.
c) The shape and charge of the substrate must be compatible with the active site of the enzyme so that enzyme-aided metabolic reactions can occur.
d) The binding between the substrate and the active site is the result of different interactions, including hydrogen-binding and electrostatic-force interactions.

Final answer:

The shape and charge of the substrate must be compatible with the active site of the enzyme for enzyme-aided metabolic reactions to occur. Option c is correct..

Step-by-step explanation:

The statement that best summarizes what we have learned about substrate and enzyme binding is option c) The shape and charge of the substrate must be compatible with the active site of the enzyme so that enzyme-aided metabolic reactions can occur.Enzymes possess an active site, which is a part of the enzyme molecule that allows it to bond to a specific substrate, forming an enzyme-substrate complex. In this process, the shape and charge of the substrate must be compatible with the active site of the enzyme for the reaction to occur.

For example, if the active site of an enzyme has a specific shape and charge that matches a substrate molecule, it can bind to the active site and undergo a reaction with the enzyme. However, if the shape or charge of the substrate does not match the active site, it will not bind effectively, and the reaction will be slowed down or prevented.
