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 else can I help you with?
Why is the sturcture of an enzyme so important?
It is important because with any shape its no use like a can, without a can opener you can't use the food in the can that's why its important that enzymes have a specific structure like a key to unlocking a specific lock, so it can use that enzyme
Why their structure shape is so important (hintactive site)?
The shape of the active site is very important because it determines the efficiency of the specific enzyme. If an active site shifts, the substrate can no longer bind to an enzyme's active site, therefore causing inefficiency. We say that the enzyme is undergoing denaturation.
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.
An enzyme that breaks down starch will also break down proteins?
Proteases are enzymes which break down proteins. Each enzyme can only break down one substance (they are specific to one substrate). This is because their active site has a specific shape to fit a protein and will not fit a starch molecule.
What is the difference between an enzyme and a catalyst and how are they similar. Please be very specific for me?
An enzyme is a type of biological catalyst, which means it speeds up chemical reactions in living organisms. Enzymes are specific to the reactions they catalyze and are usually proteins. Catalysts, on the other hand, are substances that speed up chemical reactions without being consumed in the process. Both enzymes and catalysts lower the activation energy required for a reaction to occur, increasing the rate of reaction.
What do enzymes have to help them fit their substrates the molecules that attach to the enzyme?
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.

What is the affect of temp on enzyme activity?
It makes it grow very big
What location on an enzyme is very specific to a particular reactant?
The active site.
Why is hair not an enzyme?
Hair like enzymes are made of protein. However for a protein to be an enzyme it must have a very specific tertiary structure (shape) and have an active site that has a complementary shape to part of its substrate molecule. ie the enzyme must fit with the thing that it breaks down The tertiary sructure of hair is not highly folded and does not have a complementary shape to a substrate molecule therefore it is not an enzyme
Would you expect a fat and a sugar molecule to be acted upon by the same enzyme?
No, typically fat molecules are broken down by lipase enzymes, while sugar molecules are broken down by amylase or sucrase enzymes. Each enzyme is specialized to break down specific types of molecules based on their chemical structure.
Why their structure shape is so important (hintactive site)?
The shape of the active site is very important because it determines the efficiency of the specific enzyme. If an active site shifts, the substrate can no longer bind to an enzyme's active site, therefore causing inefficiency. We say that the enzyme is undergoing denaturation.
Which methods you can use to determine the primary structure of an enzyme?
Off the top of my head: techniques such as chemical and enzymatic degredation (particularly if they are targeted) coupled with various analytical techniques particularly mass spectrometry and NMR. X-ray crystallography could also be used if the enzyme can be crystallised.
How many different types of substrates can an enzyme react with?
An enzyme typically acts on one specific substrate or a group of similar substrates due to its unique active site structure. Enzymes are highly specific, recognizing and binding to their substrate(s) based on complementary shapes and chemical properties. This specificity allows enzymes to carry out essential biological reactions efficiently.
How does an enzyme become denatured?
An enzyme becomes denatured when: A) the temperature exceeds the optimum temperature for that enzyme (ie the temperature that it works best at) B) the pH of the surrounding of the enzyme is too low or too high for the optimum pH for that enzyme. When enzymes are heated up too much they vibrate so vigorously that the bonds holding the protein structure in its specific shape becomes broken. The enzyme shape changes and the substrate no longer fits in to the active site. An enzyme which has become denatured is permanently inactive and will take no further part in reactions.
What two ways does ribulose 5 phosphate inefficient compared to other enzymes?
it is slow and not a very specific enzyme
