Study Notes

Enzymes

Substrates are the molecules upon which enzymes act.
Enzymology is the study of enzymes.
The unique three-dimensional structure of an enzyme is responsible for its specificity.
Enzymes are known to catalyze over 4,000 biochemical reaction types.
Enzymes are distinguished from most other catalysts by their high degree of substrate specificity.
Orotidine 5'-phosphate decarboxylase has the unique property of being one of the most proficient enzymes, releasing almost all of the energy available from the reaction.
Catalytic RNA molecules are called ribozymes.
The field of pseudoenzyme analysis is focused on identifying and characterizing proteins that resemble enzymes but lack catalytic activity.
An enzyme's specificity is responsible for its ability to catalyze a specific reaction or set of reactions.
The main role of enzymes as biological catalysts is to increase the rates of chemical reactions in living organisms.
