You can use the Enzyme Notes on this site to help access this information.
- Define enzyme and active site
- Explain enzyme-substrate specificity (lock and key)
- Explain the effects of temperature, pH, and substrate concentration on the enzyme activity (and be able to identify and/or sketch the graphs)
- Define enzyme denaturation and describe ways in which it occurs
- State that metabolic pathways consist of chains and cycles of enzyme-catalyzed reactions.
- Describe the induced-fit model for enzymes (extension of lock and key model)
- Explain that enzymes lower the activation energy of the chemical reactions that they catalyze (and be able to identify this effect on a graph)
- Explain the difference between competitive and non-competitive inhibition, with reference to one example of each.
- Explain the control of metabolic pathways by end-product inhibition, including the role of allosteric sites.
An enzyme is a protein or RNA produced by living cells, which is highly specific and highly catalytic to its substrates. Enzymes are a very important type of macromolecular biological catalysts. Due to the action of enzymes, chemical reactions in organisms can also be carried out efficiently and specifically under mild conditions. enzyme definition
