Enzymes Enzymes are the sparks that start the essential chemical reactions our bodies need to live. They are necessary for digesting food‚ for stimulating the brain‚ for providing cellular energy‚ and for repairing all tissues‚ organs‚ and cells. There are three types of enzymes: metabolic enzymes‚ digestive enzymes‚ and food enzymes. Metabolic enzymes catalyse‚ or spark‚ the reactions within the cells. The body’s organs‚ tissues and cells are run by metabolic enzymes. Without them our bodies

Project Enzymes are organic catalysts produced by living organisms which aid in the progression of specific biochemical reactions without undergoing any permanent chemical changes themselves. They are complex‚ conjugated proteins necessary and required to sustain life. Today‚ enzymes are also used world-wide in a variety of different industrial applications such as the production of paper‚ wine fermentation‚ and bio-remediation. One of the most important industrial applications enzymes are used

the chemical and physiological properties of this particular enzyme and determined whether the lactase came from human cells or bacterial cells. In the statistical analysis statistical formulas and techniques are used to analyze the significance of a set of data and the validity of the conclusions made based on that data. These are some terms and definitions that will be crucial to understanding the validity of this experiment. An enzyme is a protein that acts as a catalyst to lower the activation

scale Enzyme applications 1. Detergents Bacterial proteinases are still the most important detergent enzymes. Lipases decompose fats into more water-soluble compounds. Amylases are used in detergents to remove starch based stains. 2. Starch hydrolysis and fructose production The use of starch degrading enzymes was the first large scale application of microbial enzymes in food industry. Mainly two enzymes carry out conversion of starch to glucose: alpha-amylase and fungal enzymes. Fructose

grouped into primary events that include the metabolism of residual lactose and of lactate and citrate. There are different types of cheeses because there are many enzymes that are used to make the cheese‚ and also there are endless forms of molds that help age cheese giving each cheese its distinctive taste‚ texture and appearance. Enzymes are used in many food production processes to speed up the chemical reactions‚ which reduces water usage and energy consumption. The original objective of cheese

Enzymes and Their Importance in Plants and Animals Enzymes are large proteins that are responsible for catalysing thousands of metabolic processes that sustain life. Enzymes work similarly to those catalysts used in industry by lowering activation energy and therefore dramatically speeding up the rate of a reaction‚ however‚ these biological catalysts are highly selective to their substrate. Almost every chemical reaction that occurs in a cell requires enzymes in order to occur at rates required

Enzyme Inhibition Many drugs exert their action by inhibition of an enzyme activity in the body. If the activity of an enzyme is vital to the cell or organism‚ then inhibition may lead to death of the cell or organism. It is now possible to design new drugs which are enzyme inhibitors once a target enzyme has been identified. Types of Inhibitors A) Reversible Inhibitors: The effect of the inhibitor is instantaneous‚ and it can be removed from the enzyme by dialysis so that the enzyme activity

Enzyme Lab Marcus James. December 20‚ 2013 HL Biology 3 Period 1 Purpose and Background The purpose of this lab is to explain how enzymes act as catalysts for biological reactions in different temperatures. This lab relates to enzymes‚ proteins‚ and substrates; that we learned in class. The union of the enzyme and the substrate is called the enzyme-substrate complex. The make-up of an enzyme is proteins and made up of chains and amino acids. Enzymes

What effect does temperature have on the oxygen production of enzymes in an animal’s liver? A temperature which is too high would be able to produce little to no oxygen because of the extreme temperature. Just like a temperature too high‚ a temperature which is too low would also produce little to no oxygen for the same reason. Animals that have livers are considered warm-blooded‚ with very warm temperatures; therefore it would make sense for a warm temperature to produce the most oxygen; but one

The Rate of Reaction that Enzyme Concentration‚ pH‚ and Temperatures Have on the Amylase Enzymes Color Disappearance Abstract: Compare reaction rates of the concentrations‚ pH’s‚ and temperatures of the enzyme Amylase. At what concentrates do the substrate molecules collide with each other‚ making the reaction possible? At what pH levels do the 3D molecular structures change breaking the H-bond and/or denaturize? At what temperatures do the collisions of the substrate molecules happen
