Models to describe the enzyme substrate interactions

models of enzyme

There are two proposed models for explain the enzyme substrate interactions. Lock and key model Induced fit model 1. Lock and key model. This model is proposed by Emil Fisher in 1984 as a result of studies carried out on enzyme specificity. This hypothesis states that the enzymes are structurally complementary to their substrates, as … Read more

Introduction of Enzymes

Enzymes

An introduction to Enzymes – specific catalysts.                           Most are proteins. Few RNAs have enzymatic activity. Catalyze biochemical reactions. Increase the rate of reaction. Act repeatedly. Needed in small quantities. Substrate specific. Normally aqueous medium is required. Have high molecular weights. Catalytic activity is lost when they are denatured or dissociated in to subunits. Some enzymes … Read more

Introduction of Proteins

Proteins

Proteins – poly-peptide chains. Proteins are the most versatile molecules of natural bio molecular plans. From a chemical point of view, proteins are the most structurally complex and functionally sophisticated molecules which are made up of twenty amino acids with different chemical properties joining with peptide bonds. Proteins are therefore known as polypeptides. Each type … Read more

Eutrophication

What is Eutrophication? Eutrophication is an outcome of the process of adding excessive nutrients like nitrates, phosphates and organic matter into a lake or other water body. Algal blooming usually caused by runoff of nutrients such as animal waste, fertilizers or raw sewage from the land. This causes a dense growth of plant life in … Read more
