LAB EXERCISE 2 THE PHYSIOLOGY OF SKELETAL MUSCLE (Martini p. 306-316) Work in groups of 4 Objectives: Name and describe the phases of a muscle twitch. Explain why the "all or none" law is reflected in the activity of a single muscle cell but not in an intact skeletal muscle. Understand that the graded response of skeletal muscle is a function of the number of muscle fibers stimulated and the frequency of the stimulus. Define and explain the physiological basis of the following: - subminimal‚

Introduction This report will investigate the six essential nutrients required in our diet. The report will provide the function of each nutrient and explore why they are vital for the body. Carbohydrates Carbohydrates are the most important nutrient for the body as it is the largest possible source of energy. Carbohydrate supplies the body with energy‚ which allows the brain to function more effectively and allows organs to operate sufficiently. When the body has energy this allows each

Enzyme Lab Report Introduction: Enzymes are proteins that enable chemical reactions. In the enzyme lab‚ the effects of concentration‚ temperature and pH on the functionality of the enzyme catalase. The enzyme lab was also about measuring reactions by capturing the oxygen that was generated by the reaction. Materials and Methods: Experiment 1‚ 2‚ & 3 Experiment 1 examined the effects of concentration on catalase activity. Experiment 2 examined the effects of concentration in temperature

Formal Scientific Lab Report Osmosis Katy Hunter 10-26-2012 Abstract: The objectives of this lab was to be able to create models of cells with the dialysis tubing to show us how the plasma membrane is selectively permeable‚ to study the effects of osmosis on a model cell‚ and to foresee the effect of solute concentration on osmosis. In order to achieve these objectives‚ we had to fill the dialysis tubing with either water‚ or different amounts of sucrose. We then tied off the tubes and put

The temperature of water was determined by a thermometer. 1 cm stripped ends of the wires was hooked into the input posts on the back of the impendence converter. Lab tutor module was started after. B. Baseline heart rate The top of the container was covered with foil and the animal was allowed to sit quietly for 10 min. The trace was examined by pressing start. After that the baseline or the controlled

Lab Report Microscopic Study: Investigating Osmosis in Red Blood Cells Lab Report Investigating Osmosis in Red Blood Cells Introduction: The flow of water across a permeable membrane is called osmosis‚ and during this process‚ water moves down its concentration gradient. A solution surrounding a cell is hypertonic if it contains more solute particles than the inside of the cell‚ and the water will move out of the cell into the surrounding hypertonic solution by osmosis. If the solution

Lab Report Microbiology Introduction Bacteria can be found almost anywhere. For human life‚ some help us‚ some hurt us‚ and others are neutral. It is now known that good bacteria‚ or normal microflora‚ can reach 1014 microbial cells. This is far more than the 1013 cells that make up the human body (Tannock‚ 1995). The total number of bacteria on Earth is estimated to be around 4-6 x 1030 (Horner-Devine‚ 2004). It is important to know the extent of bacteria‚ how they live‚ and how they are

Genetics of Drosophila Lab Report: The test of heredity in fruit flies In my testings with breeding the fruit flies‚ I learned that the purpose of breeding them was to test how genetics pass from generation to generation‚ also known as heredity. We attempted to breed the flies and get them as close to a 9:3:3:1 ratio as possible. This would lead to an acceptable trait ratio. My hypothesis was that if we were to breed the flies in a stable environment‚ the most common fly (or the fly with the highest

absorbed by the colorimeter. This could have affected the results because light could have reached the tubes causing some of the pigment to be damaged and not give accurate results. There are not many solutions for this but I suggest that we perform the lab experiment with sufficient time to do all of it in one day permitting more exact results on how much green light will be
