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.
