Do an enzyme And its substrate fit together like a lock and key?
Enzymes are proteins that have a very specific structure. The region on the surface of an enzyme that is responsible for binding and converting the subtract into the product is called the active site.
Why is it necessary for a cell to produce one enzyme molecule for every substrate molecule that needs to be catalyzed?
Because evey substrate needs its own enzyme. Every substance has it depends upon the dissociation constant for the enzyme/substrate interaction. Some enzymes can catalyze reactions for low-affinity substrates, as long as the concentration of substrate molecules is great enough.
How enzyme structure makes an enzyme very specific?
Enzymes are proteins, which are made up of amino acids. Each enzyme has a different sequence of amino acids and changing even one amino acid will mean that the tertiary structure of the enzyme will be lost and so will it's active site. As enzymes are substrate specific, only a certain substrate will bind to its active site, due to its amino acid sequence determining the shape of the active site.
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 does a enzyme-substrate complex do?
An enzyme-substrate complex is formed when a subtrate molecule binds with the active site of an enzyme that is of similar shape and size. The active site of the enzyme will alter slightly to combine with the substrate molecule. This will put an strain on a particular bond of the substrate molecule, which will lower the activation energy for the reaction as the bond will break more readily. The substrate is then catalysed.
What is an enzyme's active site?
An enzyme's active site is a groove or dip in the enzyme that is shaped for a particular substrate to attach to.
What to enzymes do in an enzyme-substrate?
in an enzyme-substrate complex, the enzyme acts on the substrate .
What enzyme speeds up a chemical reaction is known as?
All enzyme's are catalysts for certain chemical reactions. Each enzyme will only work with a certain substrate one analogy being that the enzyme is a key and the substrate is a keyhole, and each enzyme has a unique enzyme.
The binding together of an enzyme and a substrate forms a what?
enzyme-substrate complex
What is it called when and enzyme and substrate come together?
The binding of an enzyme and a substrate forms an enzyme-substrate complex. It lowers the activation energy of a chemical reaction

Is a substrate an enzyme?
NO. The enzyme acts on the substrate. The substrate is the chemical/compound being altered by the action of the enzyme. They are NOT the same.
The substance acted upon by an enzyme is called its?
A substrate is the substance acted upon by an enzyme. The enzyme substrate complex is when an enzyme molecule combines with its substrates.

When properly aligned the enzyme and substrate form an enzyme substrate?
complex
