Hydrogen Ion. C3H6O3----->C3H5O3++H- C2H3OHCOOH--------->C2H3OHCOO+ +H- Hydrogen ion is the acid in lactate acid‚ it interfere with electrical signals in muscles and nerves‚ slows energy reactions‚ and impairs muscle contraction. The burn up we feel in intense exercise is the cause of hydrogen ion. During this experiment(Muscle fatigue lab) it will be seen that after a while of squeezing a small ball there won’t be the same amount of energy that was started with first and you will feel a burn in your

Review Sheet Exercise 3 Neurophysiology of Nerve Impulses Eliciting (Generating) a Nerve Impulse 1. Why don’t the terms depolarization and action potential mean the same thing? They require different things. Action potential requires depolarization and repolarization. Depolarization doesn’t require anything. 2. What was the threshold voltage in Activity 1? 3.0V 3. What was the effect of increasing the voltage? How does this change correlate to changes in the nerve? The action potential

Uniformly Distributed Impulse Noise Removal Rajoo Pandey structure. Another approach followed in [8] uses a differencetype noise detector and the noise detection-based adaptive medium filter. The boundary discriminative noise detection (BDND) filtering scheme proposed in [9] detects the impulse noise by employing two different size of filtering windows before the filtering operation. Most of these filtering techniques assume the presence of salt and pepper type of impulse noise. The detection of

Paper Clip Lab By: Daniel Del Carmen Mrs. McCormic IBH Biology 12 August 30‚ 2012 Background Information: You should find on some parts of your body you can feel the separate points when they are only a few millimeters apart‚ while for other parts of the body you may need a centimeter or more between them. When we touch something‚ it changes the shape of our skin slightly. We have nerve cells in our skin that detect these changes in shape and send a message to our brains‚ letting us

Project 3.2.2: Digestive System Design Introduction During his or her lifetime‚ the average person eats his/her way through at least 20 tons of food. Meats‚ vegetables or sweets - whatever your diet‚ that’s 40‚000 pounds! Our digestive system works to turn this enormous amount of food into substances that the body can use for energy and for growth and repair. But what actually happens to these foods once they enter our bodies? How does the body process each tasty bite and harness the power locked
