humans‚ is enzyme that catalyzes the hydrolysis of starch into simpler compounds. Its enzymatic activity is affected by several factors‚ such as temperature and pH. The rates of enzymatic activity of salivary amylase in different temperatures and pH were measured and resulted to be very near 50 C and 7 respectively. However‚ due to some errors that were committed‚ the expected optimum temperature was not achieved. Introduction Of all biomolecules found in the cells and organisms‚ the enzymes‚ because

ABSTRACT Enzymes are highly specific and can distinguish isomers of the same molecule. The enzyme invertase specifically catalyzes the reaction of the conversion of sucrose to its individual carbohydrates glucose and fructose. It does not catalyse the reaction of maltose to 2 glucose or lactose to galactose. In this experiment‚ titrimetric and spectrophotometric methods were used to determine the specificity of invertase by determining the amount of glucose converted from the given disaccharides

Short answer questions – generally complex by their nature and require knowledge and integration of several different concepts 1. Explain what are the end goals of reproductive cloning and therapeutic cloning. Outline the steps both procedures share and the step(s) specific for each procedure. • Reproductive Cloning- Reproductive cloning is a type of cloning which is performed for the purpose of creating a duplicate copy of another organism. It is accomplished using a process called somatic cell

temperature conditions. Introduction Before doing research on amylases‚ an explanation of enzymes is needed to fully understand each part of the experiment. An enzyme is a protein that helps speed up a chemical reaction (Raven‚ 2011). An enzyme is a catalyst‚ which is made by living cells; usually enzymes assist in developing the metabolic process of cells (Underkofler et al‚ 1958). The way in which enzymes speed up the chemical reaction is by lowering the activation

Cell Biology- Osmosis‚ Cell Size and Diffusion and Enzymes 1.0 INTRODUCTION Cells are the basic building blocks of all living things. They provide structure for the body‚ take in nutrients from the food‚ convert those nutrients into energy‚ and carry out specialized functions. Cells also contain the body’s genetic material and can make copies of themselves. A cell is also a metabolic compartment where many different chemical reaction occur. There are two types of cells‚ eukaryotic and prokaryotic

The optimum temperature for amylase production was found to be 37°C. Amylase production occurred at pH 3.0-9.0 with a maximum at pH 5.0. The best enzyme activity was observed at pH 6.0 and temperature 70°C. Key Words: Bacillus sp; solid culture; α-amylase. Alpha amylase (EC3.2.1.1‚ 1‚4alpha-D-glucan-glucanohydrolase) is an extracellular enzyme‚ which is involved in the starch processing industries where it breaks starch down into simple sugar constituents (Reddy et al.‚ 2003; Asgher et

Measurement of Enzymatic Activity of Acetylcholinesterase (AChE) Nicole Tallian Dan Lappe‚ Dan Ahmadizadeh‚ Francesca Iacono Jason O’Rawe Bio 204 L60 10/8/11 Introduction The most important enzyme for muscle and nerve movement is acetylcholinesterase (AChE) (Zapletalova). An enzymes job is to attach to one of the reactants‚ or the substrate‚ and lower the biochemical activation energies. AChE uses hydrolysis to break down the neurotransmitter acetylchoine (ACh). This neurotransmitter
