Concepts Used:
Enzymes
Catalysts of biological systems can be known as Enzymes. Enzymes helps us to perform the huge variety of biochemical reactions that encompass in life are all mediated by a series of activities.
Properties of Enzymes:
Following are the properties of enzymes:
- Enzymes initiate and speed up the reaction
- The enzyme’s activity is ph dependent
- Enzymes have the capacity to forward and reverse the reaction but do not decide the direction of the biochemical pathway
- An enzyme has a particular area on which the substrate interacts to produce the desired product
- Enzyme becomes unstable at varying ph, high temperature and heat
- It have protein like characteristics
- Substrates can be catalyzed with a small number of enzymes
- Enzyme activity represents absolute, relative, group and stereo specificities
- Some enzymes perform regulatory function
- It minimise activation energy (Ea)
- The enzymes remain unaffected before and after the product formation and it can be reused
- They are soluble both in water and NaCl.
