Question
Select all the following that can be used to describe the sturcture of enzymes, the importance of the shape, and the relationship of enzyme shape and function.
Check all that apply.
1. Amino acids are linked by hydrogen bonds with various chemical groups attached to give enxymes their two dimensional shape.
2. Amino acids are linked by hydrogen bonds with various chemical groups attached to give enxymes their three dimensional shape.
3. Amino acids are linked by hydrogen bonds with various chemical groups attached to give enzymes their four dimensional shape.
4. Aminso acids are linked by peptide bonds with hydrogen bonds between nearby amino and carboxyl groups to give enzymes their two dimensional shape.
5. Amino acids are linked by peptide bonds with various chemical groups attached to give enzymes their four dimensional shape.
6. one or more polypeptide chains are folded and bond together in the fourth level of protein organization.
7. The shape of an enzyme determnes its function.
8. The number of amino acids in an enzyme determines its function.
9. The active sit binds with the substrate.
10. enzymes are substrate specific.
11. Alteration of active sites does not alter the enzymatic reaction.
Explanation / Answer
5.Amino acids are linked by peptide bonds with various chemical groups attached to give enzymes their four dimensional shape.
All enzymes are proteins. The proteins are essentially a chain of amino acids. Amino acids bind to each other by peptide bonds. And they form the quarternary structure.
6. one or more polypeptide chains are folded and bond together in the fourth level of protein organization.
An enzyme is made up of one or more polypeptide chains. The spatial organization of the files protein chain determines the function of the enzyme.
7. The shape of an enzyme determnes its function.
9. The active site binds with the substrate.
The whole enzyme do not participate in the enzyme substrate reaction. Only the active site participate in the reaction.
10. enzymes are substrate specific.
Enzymes do not react with random substrates. They are specific as explained in lock and key hypothesis.
All other options are wrong.
