The difference between speed and velocity is that Velocity also includes a direction the acceleration of gravity on earth is approximately 10m/s2 if you drops rock from a tall building‚ about how fast will it be falling after 3 seconds? 30m/s Momentum is defined as Mass time’s velocity suppose you live on the moon. Which of the following would be true? Your weight would be less than your weight on Earth‚ but your mass would be the same as it is on Earth. In which of the following

Abstract: This lab tests how temperature and pH affect how enzymes will function. The lab showed that temperature will denature an enzyme when past its optimal working temperature and won’t denature in cold temperatures‚ but have slowed molecular activity. pH will also have an affect on an enzymes efficiency‚ when out of optimal pH the enzyme will not function as it is supposed to and if to far out of the optimal pH the enzyme will change shape and no longer work. Enzymes also showed to be reusable

------------------------------------------------- Enzyme Pre-Lab Harry Kang 9/26/12 1) The purpose of this lab was to determine the rate of enzyme activity under variety of different conditions‚ such as‚ different amount of drops of enzymes and different temperature of water. The class measured the pressure in the test tube during the reaction of the substance with‚ 1.5 ml of H2O2‚ 1.5ml of H2O and different amounts of enzyme drops‚ to determine how much oxygen gas is produced during the reaction

Enzymes are naturally occurring biological catalysts that are extremely efficient and specific. Enzymes accelerate the rate of a reaction by factors of at least a million as compared to the same reaction without the enzyme. Most biological reaction rates are not perceivable in the absence of the enzyme. The term enzyme was first used by a German pshysiologist Wilhelm Kühne in 1897. There are over 700 different kinds of enzymes that have been identified. Enzymes can be classified into several categories

introduction to enzymes Enzymes are the foundation of energy and the life force in all living things. They are responsible for building‚ detoxifying‚ and healing the body. They are also the force that allows your body to digest and absorb food. Enzymes also regulate tens of thousands of other biochemical functions that take place in the body every day. Without enzymes‚ seeds would not sprout‚ fruit would not ripen‚ leaves would not change color‚ and life would not exist. Therefore‚ the study of enzymes has

Enzyme Immobilization Methods Covalent Binding: Covalent binding is a conventional method for immobilization; it can be achieved by direct attachment with the enzyme and the material through the covalent linkage [37]. The covalent linkage is strong and stable and the support material of enzymes includes polyacrylamide‚ porous glass‚ agarose and porous silica [38]. Covalent method of immobilization is mainly used when a reaction process does not require enzyme in the product‚ this is the criteria

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

Title: E. Coli Transformation with a Plasmid DNA Containing the GFP Gene Introduction: Bacterial transformation is the process of bacteria taking in and expressing exogenous DNA. This has led to many other discoveries. In order for bacterial transformation to occur the bacteria must be in a certain physical state to be able to take in DNA. This is called competency and it allows the cell membrane to be permeable so DNA can pass through. Currently researchers are studying the transformation
