Enzymes control the rate of metabolic reactions‚ they act as biological catalysts‚ which means they are used but not used up and they also control the speed of the reaction. Enzymes are proteins which means that anything that disrupts this structure such as high temperature or change in pH will affect the enzyme activity. There are many factors affecting enzyme action for example temperature effects them‚ if the Increasing the heat gives molecules more kinetic energy so they vibrate this can then

Static and Kinetic Friction Introduction The amount of friction force between two surfaces in contact depends on the type of the surfaces in contact and the amount of compression between the surfaces. Static friction is the force that is acting against your force before the object begins to move. If you exert a small push on the box‚ the box will not move because static friction is directly opposite to the push. If you apply a greater force than the static friction force‚ the friction increases

Kinetic and Thermodynamic Reaction Condition Brandon Bullock 2/10/15 Objective The purpose of this experiment is to test kinetic theory by running several reactions and determine which product are formed under kinetic conditions and which products are formed under thermodynamic conditions. Kinetically controlled products have low transition states. This makes it easy for the product to be formed at low temperatures

Computer Enzyme Action: Testing Catalase Activity 6A H2O2 is toxic to most living organisms. Many organisms are capable of enzymatically destroying the H2O2 before it can do much damage. H2O2 can be converted to oxygen and water‚ as follows: 2 H2O2 → 2 H2O + O2 Although this reaction occurs spontaneously‚ enzymes increase the rate considerably. At least two different enzymes are known to catalyze this reaction: catalase‚ found in animals and protists‚ and peroxidase‚ found in plants. A great

The Effects on Enzymes By Bailey Rose The Effects on Enzymes Bailey Rose 10/31/2011 Abstract In this lab exercise‚ the study of enzyme catalase‚ we viewed the breakdown of hydrogen peroxide into water and oxygen. The purpose was to isolate catalase from starch and measure the rate of activity under different conditions. Changes in temperature and pH along with Substrate Concentration and Enzyme Concentration were the conditions tested in the experiment. Our class performed

Salt (Sodium Chloride) Equilibrium On part (A) we are to observe which reaction rate is faster‚ and doing the experiment. We have concluded that: “Aluminum had faster rate of reaction rate than iron because it is more active than iron based on the activity series.” TABLE B. Temperature (C) Time to complete the reaction 30’C 22 seconds 50’C 20 seconds 70’C 18seconds In this part‚ we have concluded that as temperature increases‚ the reaction rate increases also. TABLE C.

Cardiovascular Endurance I did the 1 mile walk and my time was 17 minutes and 26 seconds. My heart rate at the end of my walk was 100 bpm. My VO2 max was a 48.72 and for my people are around my age that just ranked in the category of just good. I was not able to perform the 3 minute step test because of medical reasons. The benefits of the step test would be that there is not a lot of energy being exerted by the participants. Unlike running‚ stepping comes natural making this test less challenging

on the rate of enzyme activity of Catalase Aim To investigate the effect of substrate concentration (manipulated by increasing concentration of hydrogen peroxide) on the rate of enzyme activity of catalase‚ produced by liver cells‚ on the decomposition of hydrogen peroxide. Introduction Enzymes are biological catalysts that increase the rates of reactions. In an enzyme-catalyzed reaction‚ the substrate binds to the active site and forms enzyme-substrate complex with the enzyme through the lock

Enzymes are organic catalysts‚ usually proteins that speed up metabolic reactions. They lower the amount of energy needed for reactions to progress in cells. In enzymatic activity‚ the molecules at the beginning are called substrates. Lactose metabolism is when lactose is destroyed‚ maintained or produced. For instance‚ being lactose intolerance that’s where lactose is destroyed. Metal cofactors in enzyme activity are required to function properly. The Effect of Temperature on Enzymatic Activity:
