The Effect of Concentration‚ pH and Temperature on Enzyme Activity Biology For Majors October 4‚ 2012 Abstract We examined the reaction an enzyme has when its concentration‚ pH and temperature are altered. In order to do this‚ we added different levels of pH into different test tubes with the enzyme (sucrose)‚ and substrate (sucrose)‚ and we then inverted the tube. The higher pH produced more enzyme activity. Temperature effects enzyme activity by decreasing its stability when the temperature

1) What factors affect the color of meat and poultry? There is a protein called myoglobin that is purple. When it comes into contact with oxygen‚ it changes to oxymyoglobin and the resulting color is a bright red. In addition‚ meat color is affected by age (of the animal)‚ the species‚ sex‚ diet‚ and the level of exercise it received. While safely storing meat in a fridge‚ it is normal to experience color changes. 2) Does a change in color indicate spoilage? A change of color does not necessarily

Meat and Maggots Joanne Lorenz SC1130: Week 1 Exploring the Scientific Method April 14‚ 2013 Dustin Childress Meat and Maggots This week we were asked to attempt a scientific experiment‚ I attempted to observe 2 jars‚ in each jar I put a piece of meat. On one of the jars I placed a stopper and on the other I left it open so that the air can get to the meat. I then watched for 3 days to see what happens. The question that I was trying to find out is do fly’s

In the poem "The Meat Works" by Robert Grey. A man is working in a meat works and does not like his job but it is necessary so he can make money. The purpose of this poem being written was to show that people have to sacrifices and put up with things they do not enjoy to survive. One emotion witch comes up in the meat works is despair. Robert Grey has formed a free versepoem. An example of this is "but I settled for one of the low paid jobs‚ making mince sigh the furthest end from those bellowing

The Psychological Effect of Popular Media on the Increase of Crime Over time‚ it has been observed that people have a tendency to learn from the world around them and from the people they interact. The phenomenon of learning within a social context by observation can be termed as social learning. Most individuals tend to observe and replicate the behavior of things with which they come in frequent contact and this is more likely to occur if their feel an emotional attachment with the object

Effect of physical training on the capacity to secrete epinephrine M. Kjaer and H. Galbo +Author Affiliations 1. Department of Medical Physiology B‚ Panum Institute‚ University of Copenhagen‚ Denmark. Abstract Epinephrine responses to hypoglycemia and to identical relative work loads have been shown to be higher in endurance-trained athletes than in untrained subjects. To test the hypothesis that training increases the adrenal medullary secretory capacity‚ we studied the effects of

Part B: Practical Report The Effect of Temperature on Enzyme Activity Aim: To investigate how temperature effects the enzyme catalase. Hypothesis: If the temperature of water is increased then the enzyme will react quicker to form oxygen and water‚ when compared to cold water. Purpose: To design and conduct a plan of a practical about the effects of temperature on enzymatic activity with a partner. Introduction: An enzyme is a protein‚ which speeds up a specific chemical reaction without altering

Danger in Packing Meat In Eric Schlosser’s "The Most Dangerous Job" Is about the working conditions in slaughterhouses the employees go through on a daily bases. Schlosser writes his story with how cows are slaughtered for packing‚ then you realize he is really making a point about the hazardous conditions employees are forced to work in. According to Schlosser " The "IBP revolution" has been directly responsible for many of the hazards that meatpacking workers are now forced with" (658). To keep

of the drag force on a circular cylinder. The devices used in this experiment were a fan‚ closed-channel venturi-shape pipe‚ a Pitot tube‚ circular cylinder with holes of different angles‚ U-tube manometers and a barometer. INTRODUCTION When a fluid is passing through an object‚ it produces a total force on the object. This force is a combined force of lift and drag forces (Anderson 2007). External flows past objects have been studied extensively because of their many practical applications. For
