1. INTRODUCTION 1.1 ENZYMES THE ENZYMES SPEAK!! “We are the catalysts of the living world! Protein in nature and in action specific; rapid and accurate; huge in size but with small active centres; highly exploited for disease diagnosis in lab centres”. DEFINITION Enzymes may be defined as biocatalysts synthesised by living cells. They are protein in nature (exception RNA acting as ribozyme) colloidal and thermo-labile in character and specific in their action. HISTORICAL BACKGROUND In

1. How do fungi obtain food? Once obtained‚ how is the method that fungi use to digest food similar to how animals digest food? How is it different? a. Fungi obtain their food by absorption from their surroundings such as soil‚ living and dead plant/animal material. Animals digest food by consuming them and digest them through their digestive systems in their bodies. Fungi on the other hand‚ excrete digestive enzymes onto the food and digest them outside of their system. Then they use hyphae to

Before synthetic fibers were developed‚ artificially manufactured fibers were made from cellulose‚ which comes from plants. These fibers are called cellulose fibers. Advantages[edit] Synthetic fibers do not depend either on an agricultural crop or on animal farming. They are generally cheaper than natural fiber. Synthetic fibers possess unique characteristics which make

Fiber is material that we cannot digest (the cell wall in plants made of a carbohydrate called cellulose is very difficult to digest Dietary fibers are often described as nonstarch polysaccharides. Fiber is also known as roughage is essential in the human diet to help exercise the muscles of the digestive tract. An adequate amount of fiber in

polysaccharide. Carbohydrates have many uses such as: for energy‚ for storage of food in both plant and animal cells e.g. Starch‚ chloroplasts‚ for structure in plant cells e.g. cellulose have a structural use in plant cell walls giving it structure. Carbohydrates are sweet and soluble in water with the only exceptions of starch and cellulose. Reducing sugars react with the copper in Benedict’s reagent to form a brick-red precipitate. Non-reducing sugars however do not react with Benedict’s reagent because

Sacchromyces cervesiae and Fusarium oxysporum respectively. Introduction A variety of lignocellulosic materials like agricultural residues‚ municipal and industrial wastes are being investigated for bioethanol production (Ying et al.‚ 2009). Cellulose is an abundant biopolymer on the earth and is considered the best renewable energy resource (Rezaei et al.‚ 2008). The major limitations exist for the productions of ethanol from agricultural wastes due to physical and chemical associations
