Enzymes are almost all proteins. They are often globular proteins. We can describe them in terms of their primary, secondary, tertiary and quaternary structure. They are long chains of amino acid units held together by peptide bonds, looped and folded into secondary and tertiary structures by disulfide bonds, hydrophobic interactions, and salt bridges.
the fast ones
This depends on the enzyme. Temperature, pH, and the presence of co-factors, or allosteric inhibitors.
pH, temperature, salt concentration are just some of the factors
You have probably only one important enzyme, that is present in saliva. That is called as 'Ptyalin'. This enzyme brakes down the carbohydrates to sugar. This enzyme continue to act in stomach also for some time, till acid in the stomach makes the enzyme ineffective.
endospore
Folds,Faults,Joints and Un-comformities are some important Geological Structure.
This depends on the enzyme. Temperature, pH, and the presence of co-factors, or allosteric inhibitors.
One is cofactor A.
Enzymes are catalysts that speed up chemical reactions. Some environmental factors that can affect enzyme activity are temperature and pH levels.
Substance concentration, enzyme concentration, temperature and PH level
Locamotion, cell movement, biosynthesis
pH, temperature, salt concentration are just some of the factors
The enzyme's surface folds are complementary to the substrate's surface folds.
Many things can denature proteins. Proteins have different optimal ranges in pH and temperature and outside of these optima then the enzyme will not work as well or at all. Also specific detergents will denature an enzyme depending on the enzyme.
Blocking of enzyme activity depends on various factors such as concentration of substrates, pH, temperature, some durgs. As for example rifampicin durg blocks RNA polymerase II activity.
