All of the following apply to enzyme structure and function
EXCEPT: (choose what does not apply to the question)
A. enzyme active sites function to lower the activation energy of
substrate molecules B. enzymes may require coenzymes that change
the shape of the active site C. enzymes increase the speed of
chemical reactions D. enzymes may have allosteric sites that are
used to regulate substrate-active site binding E. enzymes may
require cofactors such as Ca++ that improve the binding of the
substrate to the active site AB. all of the above are properties of
enzymes, no exception AC. none of the above are properties of
enzymes
Homework Answers
All the given points from A to E are true about enzymes. Enzyme active sites do function to lower the activation energy of substrate molecules and they may require coenzymes that change the shape of the active site. Enzymes increase the speed of chemical reactions also they may have allosteric sites that are used to regulate substrate-active site binding. Along with co-enzymes, they may also require cofactors such as Ca++ that improve the binding of the substrate to the active site.
Hence the correct option is likely to be AB i.e, all of the above are properties of enzymes, no exception

Which statement about enzyme catalysis is false? All of the active site amino acids are next to each other in the primary sequence. Enzymes speed up reactions by forming specific non-covalent bonds between the enzyme amino acids and the transition state molecule. Some enzymes require other molecules, called cofactors, to carry out chemical reactions. Generally, the most important amino acids for an enzyme's function are those in the active site.

Part A - Overview of enzyme structure and enzymatic reactions Enzymes are large globular proteins. Much of their three dimensional shape is the result of interactions between the R (variable) groups of their amino acids. The active site is the portion of the enzyme that will interact with the substrate the molecule that the enzyme acts upon. The nature and arrangement of amino acids in the active site make each enzyme specific to a substrate and to the reaction it...
