Enzymes that are produced only when substrate is present are termed?
induced enzyme
Where does an enzymes join with a substrate?
The enzyme substrate complex
What is the name given to the substance that an enzyme works on?
An enzyme will alter its substrate although the specific substrate depends on the enzyme.
What is enzyme cooperativity?
If an enzyme has two or more subunits, a substrate molecule causing induced fit in one subunit can trigger the same favorable conformational change in all the other subunits of the enzyme. Essentially, enzyme cooperativity is a mechanism of amplification regarding the response of enzymes to substrates: One substrate molecule primes an enzyme to accept additional substrate molecules more readily.
What are the molecules that enzymes act on called?
The molecule upon which an enzyme acts is called the substrate.
Enzymes that are produced only when substrate is present are termed?
induced enzyme
Substrate attaches to what part of an enzyme?
In the induced-fit model of enzymes, a substrate associates itself with which part of an enzyme?
What to enzymes do in an enzyme-substrate?
in an enzyme-substrate complex, the enzyme acts on the substrate .
Where does an enzymes join with a substrate?
The enzyme substrate complex
What is a induced fit hypothesis?
a. The substrate can be altered so it is induced to fit into the enzyme's active site. b. The enzyme changes its shape slightly as it binds to the substrate. c. The enzyme is altered so it is induced to fit many different types of substrate. d. Several sites on an enzyme can be induced to act on a substrate.
How are substrates like keys and enzymes like locks?
Enzymes have an active site that is specific for a substrate - therefore enzymes only work when the right substrate is present. The surfaces of the enzyme and the substrate fit together - like a lock and key - allowing the enzyme to fulfil its function. The theory of "induced fit" is more widely accepted - it is similar, but the enzyme shape changes to accommodate the substrate.

What is a change in the shape of an enzyme allowing it to react effectively with a substrate is a what?
An induced fit is a change in the shape of an enzyme which allows it to react effectively with a substrate. The reason for the alteration is to speed up a chemical reaction.

What is the difference between the lock and key model versus the induced fit model of the enzyme substrate complex?
The lock and key model means that the substrate must perfectly fit the enzyme, and the enzyme does not change. The induced fit model is different as when the substrate fits together with the enzyme, the enzyme itself will change to either join substrates together or break a substrate down.
What are the molecules that enzymes act on called?
The molecule upon which an enzyme acts is called the substrate.
