The catalytic site of enzyme controls its enzymatic activity. Active site is the point of attachment of substrate with the enzyme that has a specific amino acid sequence.
For example, the digestive enzyme protease breaks down the large protein molecules into smaller digestible peptides.Įnzymes are proteins and each enzyme has a specific structure consisting of active site and a catalytic site. With the help of enzymes, the substrates are converted into products that are utilized by the cell. Activation energy of enzyme is the amount of energy required to initiate a reaction. They lower thee activation energy of biochemical reaction in cells and thus speed up the rate of reaction. Enzymes are proteins having a 3D structure that needs to be maintained for an enzyme to remain functional. What are enzymes?Įnzymes are the biological catalysts that speed up the chemical reactions in cells of living organisms. Amylase enzyme catalyzes carbohydrate digestion.
Trypsin enzyme catalyzes the breakdown of proteins. Enzymes are specific for the type of reaction that they catalyze.įor example, the digestive enzymes break down the macromolecular food particle into small digestible particles. Enzyme specificity describes the tendency of an enzyme to catalyze a specify biochemical reaction by binding to specific substrate.
