The major conclusion was that catalane reacts faster in warm temperatures that are neither freezing nor boiling, catalane reforms well in lower concentrations than the substrate, and catalane prefers neutral pH levels around 7. Section 1. Enzymes are a form of proteins that act as catalysts to speed up chemical reactions without being consumed by the reaction. Enzyme acid phosphatase is found in many organisms, species and plants. Enzymes are catalysts that are used to speed up these reactions. This lab shows the affects these factors have on the rate of reaction between catalase, an enzyme found in potatoes, and hydrogen peroxide, the substrate. Assignment. I am experienced in the fields of Enzyme, physics and chemistry, and I enjoy writing on these topics. The enzymes are individuals, like the different players on a ball team, they have different specific structures and jobs.

ENZYMES LABORATORY REPORT Introduction The utilization of any complex molecule for energy by an organism is dependent on a process called hydrolysis. Search: Mcmush Lab Worksheet Answers. At very low pH and extremely high pH, the enzymes become denatured (Watson, 2014b). Increased acidity or alkalinity decreases the ability of the substrates to bind to the active site and so enzyme action decreases, a major pH change denatures the enzymes so enzyme action stops. To determine this we are going to test the amount of color absorbance by using a special tool to help us understand our results. Printer Friendly.

Enzyme inhibitors are another set of factors that reduce enzymes activity rate (Seager & Slabaugh, 2010). In this lab the behaviour and activity of these enzymes will be measured by adding enzyme extract to hydrogen peroxide and then monitoring the rate Introduction An enzyme is a protein that acts as a catalyst which reduces the activation energy needed for a chemical reaction. Hypothesis: If pH is increased or decreased past the enzymes optimum pH, the number of products produced by the enzyme will decrease because the enzyme will become denatured. Note: This is an A-level Report of coursework that achieved full marks. This laboratory report is on the topic of enzyme kinetics, previous work in this particular field was carried out in the 1700s, when biological catalyst enzymes were discovered and studied. Observe and record observations. Enzyme Lab Report Introduction: Enzymes are proteins that enable chemical reactions. The body uses enzymes in order for the body to break down food so the body can absorb vitamins, minerals, and nutrients more efficiently. Conclusion About Enzyme Activity Report Enzymes act as biological catalysts, breaking down substrates without needing a high temperature, allowing all the chemical reactions of metabolism to take place, regulating the speed at which they progress, lowering the activation energy and providing a means of controlling individual biochemical pathways. Therefore the overall aim of this investigation is to see effect of substrate concentration, presence of inhibitors, temperature and pH, on the activity of enzyme, acid phosphatase.
