a: substrate enzyme ~
b: key
What:
The substrate is like a key. Yes, for a given enzyme the substrate fits into the active site of an enzyme. But if you want this analogy to better describe the physical changes to the substrate, you have to visualize the key being cut in half by the lock. This is the affect that hydrolitic enzymes have on their specific substrate.

a: hydrolytic enzyme ~
b: molecular chain saw
What:
This class of enzymes break down bio molecules such as cellulose,protein, starch and lipid. At their optimal temperature and with their given substrate, they can break many bonds per second. It kinda like a chain saw cutting through small branches on a tree.

a: regulatory enzyme ~
b: valve in a water pipe
What:
A valve in a water pipe can be closed or opened and regulates the amount of water moving through a pipe. The activity of a regulatory enzyme can affect the production of a particular metabolic intermediate that will influence a whole series of other enzymes and products.

a: enzyme regulation ~
b: dimmer switch
What:
"Under normal circumstances, it acts by causing a conformational change in a receptor molecule, which results in a change in the binding affinity of the ligand. In this way, an allosteric ligand modulates the receptor's activation by its primary (orthosteric) ligand, and can be thought to act like a dimmer switch in an electrical circuit, adjusting the intensity of the response."

There 2 Sides With Lots Of Movement....
a: Enzyme biochemistry ~
b: football
What: "let's say that enzyme
biochemistry is like football. You can represent an enzyme's reaction mechanism with diagrams that resemble
the Xs and Os of a football play. For both football and enzymes, there's a series of steps that have to happen for
things to work. A ball carrier has to get the handoff just in time to hit the hole, for instance, and the hole
has to open when he gets there."

Looking For Dna
a: The restriction enzyme ~
b: search engine
What: "The restriction enzyme is like a "search engine". It scans the DNA looking for its recognition site. Even a single nucleotide difference will prevent the enzyme from recognizing and cutting its site. The enzyme binds to the DNA and then cuts it."

a: protein-enzyme denaturation ~
b: bending the key
What:
"An enzyme and its substrate are traditionally compared to a lock and key, so protein/enzyme denaturation is like bending the key: It stops working."
A whole book of essential analogies it is.

a: inactive enzyme in a biochemical pathway ~
b: dam across a stream
What:
"Having an inactive enzyme in a biochemical pathway is like putting a dam across a stream: you get build-up of molecules upstream of the defective enzyme"
