Enzymes and Their Functions - Activity Sheets

reaction between an enzyme and a substrate can be affected by different factors. Some of the factors that can affect enzyme activity are temperature, pH, concentration of the enzyme and concentration of the substrate. In living organisms, enzymes work best at certain temperatures and pH values depending on the type of enzyme. 1. What are ...

Liver Enzyme Lab

Liver contains a specific enzyme called catalase. When hydrogen peroxide (H 2 O 2) is added to liver, a chemical reaction occurs which results in the products of oxygen gas (O 2) and liquid water (H 2 O). The purpose of this lab is to determine if changes in temperature will have an effect on the activity of an enzyme. The reaction is as ...

enzymes, and supplements published annually have now extended this number to over 5 000. Within this system, all enzymes are described by a four-part Enzyme Commission (EC) number. For example, the enzyme with the trivial name lactate dehydrogenase has the EC number, and is more correctly called l–lactate: NAD+ oxidoreductase.

Question #2: What is the effect of substrate concentration on enzyme activity? 1. Take a fresh amount of 1% H 2 O 2 and dilute it to 0.5% (1/2 H 2 O 2 and and 1/2 water). Swirl so the solution mixes well then set up a cup that is 4 cm deep with this 0.5% solution. 2. Set up a second cup with 4 cm of fresh 1% H

Experiment 10 – Enzymes - Laney College

Jan 10, 2012·enzymes. Since enzymes are proteins, they can be denatured in a variety of ways, so they are most active under mild conditions. Most enzymes have optimum activity at a neutral pH and at body temperature. Enzymes are also very specific – they only act on one substrate or one class of related substrate molecules.

Our experimental design was to find out if decreasing the amount of substrate will affect the reaction rate of the enzyme. For this experiment we used yeast as our peroxidase.

Restriction Enzyme Lab - Weebly

Many restriction enzymes require Mg2+ for activity and recognize palindromic stretches of DNA, generally 4-8 base pairs in length. The probability that a given enzyme will cut, or “digest”, a piece of DNA is directly proportional to the length of its recognition site. Statistically, an enzyme will average one cut for every 4n base

Experiment 5: Enzyme Kinetics

Enzyme specificity toward substrate binding (as seen in the image below) is explained by two models, the lock-and-key model and the induced fit model. The lock-and-key model was the original model used to explain the enzyme-substrate complex fit whereby the enzymes and subtrates were thought to have

Baseline Activity Procedure: 1. Read the entire procedure before beginning. Pay special attention to the requirements for mixing the contents of the substrate and enzyme tubes and timing the reaction. Use a dedicated serological pipet for each solution. Precise volume measurements and accurate timing are crucial for rate studies. 2.

analysis of experiments with variable enzyme con- centrations is presented in Table 1. The results can be analyzed by statistical tests [6,7] and are directly convertible to variance as a function of velocity, because the latter quantity is directly proportional to enzyme concentration (cf. Fig.2). It is clear from

structure of the enzyme, and may also affect the ability of the enzyme to bind ("embrace") the substrate. As a consequence, the catalytic activity (i.e. the degree to which it increases the rate of the reaction) of all known enzymes is sensitive to pH, and each known enzyme exhibits its greatest activity at one pH--the enzyme's optimal pH.
