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
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
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
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

A smog is a combination of smoke and fog. The initial reaction of photochemical smog is the photolysis of nitrogen dioxide (NO2) into nitrogen (NO) monoxide and ozone (O3). [g_article_ads] Nitrogen dioxide is found in the exhaust gases given out from automobiles and industries. This NO2 dissociates in the presence of UV radiation emit with … Read more
Greenhouse Effect. Greenhouse effect is a mechanism of maintaining the temperature of our earth. The earth heats up from the radiation received from the sun and the heat is reflected back into the atmosphere in the form of infra-red (IR) radiation. The earth receives a large amount of radiant energy from the sun and about … Read more
Air pollution can be defined as the introduction of various material that cause harm or discomfort to living being including humans, natural vegetation and structures in to the atmosphere. These materials can be chemicals, particulate materials or biological materials which have the capability of acting adversely on natural ecosystem when they present in a sufficient … Read more
