Enzymes- reduce the amount of energy required for the reactions they catalyse [accelerate]. -thus‚ increasing the rate of reactions that occur in living organisms. WITHOUT enzymes : metabolism would be so slow at body temp. that insufficient energy would be available to sustain life. -Many enzymes are “Intracellular”- used within the cell that produced them e.g. enzymes in respiration & photosynthesis -Others are “extracellular”-they act outside the

ENZYME STRUCTURE AND FUNCTIONS: Enzymes are biological catalysts. They increase the rate of reactions by a factor of between 106 to 1012 times‚ allowing the chemical reactions that make life possible to take place at normal temperatures Definition of enzyme: A protein with catalytic properties due to its power of specific activation is defined as an enzyme. STRUCTURE Enzymes are proteins their function depends on its complexity. The reaction takes place in a small part of the enzyme

Cellular Biology furthers technology-Enzymes in the Dairy Industry Since ancient times‚ enzymes have played an important role in food production. Especially in the diary industry‚ some enzymes are required for the production of cheese‚ yogurt‚ and other dairy products‚ while others are used in a more specialized fashion such as improving texture or flavour of the product. Enzymes are used to catalyze the desirable reactions in industrial processes. Today‚ enzyme applications in such processing get

Dana Calderone Responses of Enzyme Activity from pH and Concentration Abstract Enzymes are the key to many of the chemical reactions that our bodies depend on to live. Without enzymes‚ we would not exist. These biological catalysts speed up the reactions as well as reduce the amount of activation energy needed to complete the process. Knowing how important enzymes are to us‚ it is important to realize what they require to function. They need select conditions and rates to work right. These conditions

David Cameron’s First Speech as Prime Minister. 2010 Her Majesty the Queen has asked me to form a new government and I have accepted. Before I talk about that new government‚ let me say something about the one that has just passed. Compared with a decade ago‚ this country is more open at home and more compassionate abroad and that is something we should all be grateful for and on behalf of the whole country I’d like to pay tribute to the outgoing prime minister for his long record of dedicated public

Explain the use of enzymes in food production by means of examples. You must include the example of lactase. Enzymes are proteins that speed up the rate of chemical reactions (up to a million times) in living organisms. Acting as catalysts they are not consumed nor altered in the process of converting the specific set of reactants into specific products. In food production‚ enzymes are greatly appreciated by their accelerated effect in biochemical processes and are mostly used in what we

concentrations; that test the reaction rates of the enzyme catalase over a fixed period of time. The major conclusion was that catalase reacts faster in warm temperatures that are neither freezing nor boiling‚ catalase performs well in lower concentrations than the substrate‚ and catalase prefers neutral pH levels around 7. Introduction Enzymes are proteins that catalyze metabolic reactions vital for the survival and functioning of cells [1]. Without enzymes‚ metabolic processes would occur at unfeasible
