What are enzymes ?
Solution and Explanation
Enzymes are proteins that catalyse biological reactions. They are very specific in nature and catalyse only a particular reaction for a particular substrate. Enzymes are usually named after the particular substrate or class of substrate and some times after the particular reaction.
For example, the enzyme used to catalyse the hydrolysis of maltose into glucose is named as maltase.
Again, the enzymes used to catalyse the oxidation of one substrate with the simultaneous reduction of another substrate are named as oxidoreductase enzymes.
The name of an enzyme ends with ' - ase'.

Questions Asked in CBSE CLASS XII exam
A ladder of fixed length \( h \) is to be placed along the wall such that it is free to move along the height of the wall.
Based upon the above information, answer the following questions:(iii) (b) If the foot of the ladder, whose length is 5 m, is being pulled towards the wall such that the rate of decrease of distance \( y \) is \( 2 \, \text{m/s} \), then at what rate is the height on the wall \( x \) increasing when the foot of the ladder is 3 m away from the wall?

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.
