Study Notes
Functions of Enzymes
- Enzymes act as biological catalysts, speeding up chemical reactions by lowering activation energy.
- They are crucial in metabolic processes, facilitating reactions necessary for life.
EC Code Number in Enzyme Nomenclature
- The Enzyme Commission (EC) code is a numerical classification scheme for enzymes.
- It specifies the type of reaction the enzyme catalyzes, providing a unique identifier that aids in enzyme identification.
Theory of Substrate-Enzyme Interaction
- The "lock and key" theory describes how substrates fit precisely into an enzyme's active site, similar to a key fitting into a lock.
- Alternatively, the "induced fit" model suggests that the active site undergoes a conformational change to better accommodate the substrate upon binding.
Study of Enzyme Kinetics
- Enzyme kinetics examines the rates of enzyme-catalyzed reactions.
- It provides insights into enzyme activity, substrate affinity, and the effects of inhibitors on reaction rates.
Activation Energy
- Activation energy is the minimum energy required for a chemical reaction to occur.
- Enzymes lower the activation energy threshold, enhancing the rate at which reactions proceed.
