Introduction: How is the human body able to digest the food that you eat? How quickly your body digests your food? This is because the human body contains enzymes that are the biological substance‚ a.k.a proteins‚ that act as catalysts and help complex reactions occur. There are many different enzymes that each have different specific functions. The enzymes include: diastase‚ pepsin‚ lipase‚ catalyse and urease. Lipase is an enzyme found in the digestive tract that catalyses the break down of fats into

Chemical Reactions Chemical reactions happen in almost everything around us. Reactions are very important in everyday life‚ and science. Chemical reactions are the changing of substances to other substances by the breaking of bonds in reactants and the formation of new bonds in products. There are different types of chemical reactions such as combination reaction‚ decomposition reaction‚ single-replacement reaction‚ double-replacement reaction‚ and combustion reaction. Combination

Redox Reactions Reactions involving oxidation and reduction processes are very important in our everyday world. They make batteries work and cause metals to corrode (or help to prevent their corrosion). They enable us to obtain heat by burning fuels--in factories and in our bodies. Many redox reactions are complex. However‚ combustion and synthesis (from elements) are two ordinary examples which require very little description. Just a little more involved are the displacement reactions‚ with

REACTIONS OF HYDROCARBONS Diane Cate Satsatin Biology Student‚ Biology Department College of Science‚ De La Salle University-Dasmarinas ABSTRACT Five substances which are Hexane‚ Eugenol‚ Unknown hydrocarbon 1‚ Unknown hydrocarbon 2‚ and Acetylene gas was used for the selective reactivity of hydrocarbons to functional group tests; Bayer’s test‚ Bromine test light‚ Bromine test dark‚ and Tollen’s test. In Bayer’s test‚ only Acetylene‚ Eugenol and Unknown hydrocarbon 2 reacted positively

Title: Surface Area vs. Rate of Reaction Research question: How can different temperatures affect the rate of reaction‚ when the reactant is in powder form? Hypothesis: If the temperature of the water is increased‚ the rate of reaction will also increase as the heat given off to the particles will increase leading to more movement and frequent collisions. Background information: Chemical reactions occur when two or more molecules interact with each other‚ but that can only occur when they

Sociological Reactions to HIV/AIDS in the 80’s‚ 90’s and new Millennium In the early stages of identifying HIV‚ it was first believed that only certain individuals were able to become infected. This group was known as the 4-H group: homosexuals‚ hemophiliacs‚ heroin addicts and Haitians. The stigma of HIV was that it infected people with promiscuous or unclean ways. Jerry Falwell‚ a televangelist‚ fundamentalist Southern Baptist pastor and conservative cofounder of the Moral Majority‚ became a

Theme of colonization in Heat of Darkness The growth of liberalism and colonialism as social and political forces took place almost simultaneously in the beginning of 19th century. Colonialism is related to the concept of imperialism. The English novelists who are concerned with the problem of colonialism are mainly E.M Forster and Joseph Conrad. Colonialism and imperialism are shaping forces in their novels. Forster’s liberalism and his depiction of the colonialism are never introduced in clear

Polymerization reaCTIONS polymers are high-molecular-weight compounds‚ fashioned by the aggregation of many smaller molecules called monomers. Ex. plastics that have so changed society and the natural and synthetic fibers used in clothing are polymers. Classification of polymers Homopolymers - consist of repeated long chains or structures of the same monomer unit. Ex. PVC(polyvinyl chloride) Copolymers - polymers that consist of more than one molecule. Trimers - molecules consisting
