CASSAVA STARCH AS A MAJOR COMPONENT IN MAKING BIODEGRADABLE PLASTIC ABSTRACT The purpose of this experiment is to be able to help the society with its environmental issues by creating biodegradable plastic out of cassava starch. The procedures that the researchers used in this investigatory project were all experimental and were based on Scientific Method. The researchers used environment-friendly materials which can be made into biodegradable plastics that will not harm the environment

Factors affecting Enzyme Activity: The effect of pH on enzyme activity Background Knowledge: An enzyme is a biological catalyst – which speeds up the reaction rate‚ without itself getting altered. Enzymes are proteins with long polypeptide chains that are folded up into three – dimensional shapes. An enzyme acts on a substrate to convert the substrate into a product useful for the organism.The active site is a special region on the surface of the enzyme where the substrate binds to the enzyme.

ANAEROBIC DIGESTION ON BIODEGRADABLE WASTE FOR METHANE GAS CAPTURE BIODEGRADABLE WASTE: Biodegradable waste is a type of waste‚ typically originating from plant or animal sources‚ which can be decomposed by other living organisms. Biomass‚ manure‚ sewage‚ municipal waste‚ green waste and plant materials are some of these common biodegradable waste. ANAEROBIC DIGESTION: This is a series of biological processes in which microorganisms breakdown biodegradable materials in the absence of oxygen

Introduction: With the execution of this experiment‚ we began to go deeper into the Cell and Molecular Biology course. The main focus of the experiment would be how the Restriction Endonucleases cleave the strands of DNA. For this experiment‚ pBR322 was the specimen to use. Restriction Endonucleases work by cleaving the sugar phosphate backbone of specific DNA sites. Restriction enzymes that have been isolated from bacteria have a defensive role. This idea is illustrated when an attacking foreign

The main structural difference between starch glycogen cellulose comes from? In: Human and Animal Interaction Starch‚ glycogen and cellulose are all polymers of glucose. They differ in the type of glucose present and the bonds which link thr glucose monomers together. Starch and glycogen are made from alpha-glucose. This is an isomer of glucose in which the hydroxyl (-OH) group attached to carbon number 1 is below the plane of the ring. Starch is itself composed of two types of polymer:amylose

1. tested and measured? The purpose of this experiment was to determine whether the dark or light coleus leaf had the presence of starch. We used a dark and light leaf to test the presence of starch and how much was produced. 2. Summarize the results and how the results were obtained. Be sure to note the reason for each treatment of the leaves. As appropriate‚ compare experimental samples to controls. Both leaves were boiled in water then placed in hot ethyl alcohol. After adding the iodine
