PH level of Amylase Background info: What is Amylase? Amylase is an enzyme that helps digest carbohydrates. It is produced in the pancreas and the salivary glands. (Dugdale & Longstreth‚ 2011) Factors Affecting Amylase: Things that affect the efficiency of Amylase are temperature and pH levels. (Wikimedia Foundation‚ Inc‚ 2013) Function in the body: The function of Amylase in the human body is to break down plant-based starch sources. Therefore‚ providing the human body with more

Enzymatic activity of Human saliva (Salivary amylase) against Temperature Proponent: Ian Angelo P. Dela Cruz BS-Biology 1-3 Prof. McJervis S. Villaruel Professor – BIOL2015(Lab) ABSTRACT This report entitled “Enzymatic activity of Human saliva (Salivary amylase) against temperature” aims to know and observe the enzyme activity of the human saliva. The research only included the use of starch-agar as the medium to observe enzyme activity during the experiment. Five starch-agar

WHY DOES THE COLOUR LEAK OUT OF COOKED BEETROOT? PLAN Hypothesis Temperature has an effect on the leaking of the colour from beetroot. This means that as the temperature is altered there will be a change in the rate of colour leakage. Scientific Background Beetroot is a very familiar vegetable and is commonly known as beet. It is famous in most recipe books that advice that its outer skin is not to be removed to avoid getting red dye in the cooking water. If we look at the internal structure

Effect of Catalase at Different Temperatures Abstract The role of this experiment is to determine the effect of temperature on enzymatic activity. The results of the experiment were the colder the temperature the slower the reaction rate and the hotter the temperature the faster the reaction rate. Introduction Enzymes are chemical substances found in living cells and they act as catalysts of the various chemical reactions that occur in them.(Preszler‚ 2012) They bind to substrates that have

attempt to observe how enzymes (starch phosphorylase in particular) are affected by varying its temperature before introducing it to the substrate it will be reacting with. A catalyst (enzyme) is a substance that changes the rate of a reaction; for a reaction to take place at all‚ the enzyme must first come into contact with the substrate. Enzymes are subject to a number of factors which effect how fast they can cause a reaction with a substrate; these factors include temperature‚ pH levels‚ chemical

The Effect of Temperature on Solubility By Aviraj Singh Rogers 2 Background: The solubility of most solid substances is generally said to increase as the temperature of the solvent increases. However‚ some substances‚ such as ytterbium sulfate‚ do the opposite. This can be explained through the Second Law of Thermodynamics which states that “in all energy exchanges‚ if no energy enters or leaves the system‚ the potential energy of the state will always be less than that of the initial state”

Effect of different temperatures on amylase activity. Literature review This study is an attempt to follow the activity of amylase because it has a major role in the life of living organisms and is found abundantly in them. Amylase is a catalytic enzyme which hydrolyzes starch into maltose and dextrin at a certain temperature (Biology.kenyon.edu‚ 2015). In plants such as fruits and vegetables carbohydrates are referred to starch which is polysaccharide and is converted into disaccharide and eventually

Enzymes are biological catalysts and each individual enzyme can only catalyse to one type of reaction – due to its specific shape. Each individual enzyme has its own specific shape which is determined by the amino acid sequence that it is made up of – each enzyme’s active site matches to its unique substrate molecule. For the sake of our experiment – enzymes catalyse reactions because they become an active site for reactions to take place. This lowers the energy that is needed for the reaction but

Practical 2.1- The Effect of Temperature on Membranes Objective To investigate the effect of temperature on membrane structure Introduction Beetroot Pigments Beetroots contain Betalains which are the red pigments present in the cell vacuole. Betalains are soluble in water and they contain nitrogen. Betalains extracted from beetroot is commonly used as food dye because it is not known to cause any allergic reactions.

Abstract: Enzymes are part of human’s everyday lives and improve the quality of living. Enzymes decrease activation energy which pertains to how much energy is needed for chemical reactions to take place. Enzymes also known as catalysts is one of the main factors in producing energy in individual’s bodies. The experiment conducted was to test how different temperatures effected the catabolizing of fungal and bacterial amylase‚ as well as the optimal temperature needed for the enzyme to correlate
