Enzymes

                                              Introduction-

• Enzymes are work as a biological catalysts that increase the rate of reaction(biochemical reaction). 
• Mainly enzymes are in 3D structure globular proteins(tertiary and quaternary structure)
• Enzyme are macromolecular biological catalysts, enzyme accelerate or catalyze chemical reaction.
• During the reaction substrate bind with the enzyme at active site of enzyme , converts into different molecule called products.
• microbial enzyme are the biological catalysts for the biolchemical reaction leading to microbial growth and respiration ,as well as formation of fermentation products. 

Structure of enzyme-

  The active site of an enzyme is a region that binds substrates ,co-factors and prosthetic groups. Active site is less than 5% of the total surface area of enzyme.active site have tertiary structure of proteins.

active site further divided into two types 

Binding site- it choose the substrate and binds to active sites 

Catalytic site- it performs the catalytic action of enzyme 

Characteristics;

• Enzyme increase the rate of reaction 
• The presence of enzyme does not effects the nature and properties of end products
• Small amount of enzyme accelerate the chemical reaction 
• Enzyme are sensitive to change in pH, temp, and substrate concentration\.
