Exercise Electrocardiogram Lab Purpose The purpose of this lab is to understand the concepts of an electrocardiogram of a normal person as well as understand what a normal ECG and an exercise ECG look like when performing a Bruce protocol treadmill test. Methods Materials- Test subject‚ ECG-12lead‚ 10 electrodes‚ treadmill The subject must have the electrodes properly connected before starting the treadmill test. Remove any hair from the subject before placing the electrodes on. The

2014 Preparation and IR Analysis of 2-chloride-2-methylbutane Line Reaction Abstract The purpose of this experiment was to react 2-methyl-2-butanol with concentrated HCl in order to form 2-chloride-2-methylbutane. The hydrogen for the HCl make the -OH from the 2-methyl-2-butanol into a good leaving group because H2O is formed. The H2O leaves and Cl- is free to bond with the carbocation creating 2-chloride-2-methylbutane. The materials needed for the lab were an Erlenmeyer flask with a stir

Purpose: The purpose of this lab is to determine the substance that are required in order for muscle to contract. We are experiencing this contraction by having three different solutions which contains their own disparate chemicals inside. Hypothesis: Solution A: 0.25% ATP solutions in distilled water; Base on muscle contraction mechanism which we know the force that generating cycle required is indeed of a lot of energy in the form of ATP‚ but there are additional solutions; KCl‚ MgCl2 which

Virtual Lab: Enzyme Controlled Reactions Worksheet 1. Which of the following does NOT apply to an enzyme: b. Inorganic 2. When an enzyme catalyzes a reaction: a. Substrate(s) bind in the active site 3. Which of the following would interfere most with the ability of an enzyme to catalyze a reaction? a. Reduced concentration of substrate available 4. Feedback mechanisms regulate the rate of enzyme activity‚ effectively “turning off” an enzyme in a reversible way until more product is needed

Muscle Contraction Tutorial/Review 1. Hydrolysis is the decomposition of a substance by the insertion of water molecules between certain of its bonds. The third phosphate is removed by hydrolysis and free energy is released. ADPneedds to have another phosphate molecule in order to become ATP and this happens through hydrolysis. This ATP can be used in the muscle contraction and relaxation. 2. When one flexes his/her arm‚ the muscle on top is the bicep. The origin of the bicep is at the tubercule

Compression. 2.6 Explain the basic principles of vector graphics and raster graphics. In vector graphics‚ an image is represented as a collection of straight and curved line segments. Simple objects‚ such as rectangles and ovals‚ and more complex objects are defined by the grouping of line segments. In raster graphics‚ an image is represented

Lab 1‚ Exercise 1 • Based on the information in Table 2‚ what patterns do you observe? The number of fish that I observed in a body of water increases until the dissolved oxygen was at 12 ppm. After that point‚ the number of fish declines slightly. • Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. When the dissolved oxygen levels increase‚ the number of fish that
