are amylases? Amylases are enzymes that break down starch or glycogen. Amylases are produced by a variety of living organisms‚ ranging from bacteria to plants and humans. Bacteria and fungi secrete amylases to the outside of their cells to carry out extracellular digestion. When they have broken down the insoluble starch‚ the soluble end products such as (glucose or maltose) are absorbed into their cells. Amylases are classified based on how they break down starch molecules i. α-amylase (alpha-amylase)

Lab Report (Effect of concentration on enzyme activity) Biology Noor Alawadhi 11- KC Introduction: An Enzyme is a protein‚ which is capable of starting a chemical reaction‚ which involves the formation or breakage of chemical bonds. A substrate is the surface or material on or from which an organism lives‚ grows‚ or obtains its nourishment. In this case it is hydrogen peroxide. This lab report will be explaining the experiment held to understand the effects of the changes in the amount of

Investigating the effect of changing substrate concentration on the activity of the enzyme catalase The aim of this experiment is to examine how the concentration of a substrate (hydrogen peroxide) affects the rate of reaction of an enzyme catalyse (found in liver cells) Research Question: how does changing the concentration of the substrate affect the rate of reaction of the enzyme catalyse? Hypothesis: As the concentration of the substrate increases‚ so does the rate of reaction until the reaction

The first step to this experiment is being completely protected from any possible harm that could possibly occur as a consequence of the practical test. Therefore‚ a lab coat‚ safety gloves with clean hands and goggles must be worn before starting the experiment. The initial room temperature should be calculated using a thermometer and a marker is used to name beakers 1 and 2. Divide the 10 test tubes into two groups and name them 1-5 in both groups. 5 different stopwatches are used to record the

Enzymes and ATP Enzymes act as protein catalysts in biochemical processes Enzymes bind to a substrate and forms the enzyme substrate complex. Enzymes work by lowering the energy of activation. Activation energy must be supplied for the reaction to begin‚ once supplied‚ the reaction can proceed on its own. Enzymes can speed up events. They are not used by during the reaction because the enzyme stays the same‚ it does not change during the reaction. (Hudon-Miller‚ Enzymes‚ 2013) Enzymes act as

certain environmental factors affect the enzyme activity rate. For the first experiment‚ where we tested the increase in concentration of enzyme with the substrate‚ we found that higher concentration of enzyme increases the rate of reaction of the enzyme. This is because more enzyme molecules are present‚ which allow more substrate molecules to get into the active sites of the enzyme (Sattler W& Esterbauer H). When calculating the absorbance of different enzyme concentration‚ it was noticeable that

The Effect of Temperature on Enzyme Activity and Oxygen Production Throughout this report you will gain information as to how temperature effects the amount of oxygen produced in an enzyme- catalase experiment. In the experiment we used liver extract as a catalase and created a chemical reaction within a reaction chamber between the catalase and hydrogen peroxide as well as three different controlled temperatures. In the procedure below there will be a step by step process as to how

RESULTS 28⁰C was the optimal temperature. 28⁰C had the maximum rate of reaction for the class data and results provided by this experiment; the results were represented graphically in graph 1 and graph 2. The reason for having 2 tables and graphs is because 28⁰C was done twice. Data for 28⁰C was collected in this experiment and it was collected again by peers in the classroom. Results are identical because all temperatures except 28⁰C was collected once from peers. Based on the results from the

BIO 5 Lab Report: Lactase Enzymes Enzymes are biological catalysts or assistants. Enzymes consist of various types of proteins that work to drive the chemical reaction required for a specific action or nutrient. Enzymes can either launch a reaction or speed it up. The chemicals that are transformed with the help of enzymes are called substrates. In the absence of enzymes‚ these chemicals are called reactants. Enzymes are thought to have an area with a very particular shape. When a molecule of
