Effects of Ach blocker- tubocurare- twitch tension declines. Blocks Ach and no muscle contraction. It is necessary for acetylcholine to bind to receptors in order for sodium ion channels to open and allow an action potential to occur in the muscle which is known as an end plate potential iii. Effects of direct muscle stimulation 2. Expected results a. Increasing amplitude- increase in twitch tension b. Increasing frequency- increase in twitch tension c. Tubocurare- decrease in twitch tension d. Direct

Study Guide: Chapters 3 and 4 Answer the following questions—you do not need to answer in complete questions. Differentiate between potential‚ kinetic and low quality energy. Potential- Energy that is stored in an object due to its configuration Kinetic- energy an object possess due to its motion and mass. Low quality- Energy that is unorganized and do little work. How does entropy relate to the continual energy needs of organisms Entropy represents the disorder of a system which allows the

potassium ions flow out of‚ the cell. The flow of ions causes a reversal in charges‚ with a positive charge now occurring on the interior of the cell and a negative charge on the exterior. The cell is said to be depolarized‚ resulting in an action potential causing the nerve impulse to move along the axon. As depolarization of the membrane proceeds along the nerve‚ a series of reactions start with the opening and closing of ion gates‚ which allow the potassium ions to flow back into the cell and sodium

INTRODUCTION In hydroelectric power plant‚ turbine been used to generate power from reservoir of water. Turbine been selected by their characteristic curves based on the potential energy available in the water and the amount of power to be generated. Turbine is a type that develops torque by reacting to the pressure or weight of a fluid. The operation of reaction turbine can be describes by the Newton’s third law of motion that is for every action‚ there is an equal and opposite reaction. In this

If we assume that the body of mass M is at rest in an inertial reference frame‚ then the total mechanical energy E of the two-body system when the bodies are separated by a distance r is the sum of the kinetic energy of the body of mass m and the potential energy of the system‚ given by Equation 14.15 E= K+U E= 1 2mv2- GMmr This equation shows that E may be positive‚ negative‚ or zero‚ depending on the value of v. However‚ for a bound system‚ such as the Earth–Sun

Essay 3 Shubham Tyagi How do our sensory systems work? Write about taste‚ sight‚ hearing and touch. Introduction Sensory systems are important to us; they let us perceive the environment. The senses can be broadly divided in to the sense of touch‚ smell‚ taste‚ vision and hearing. The seemingly simple perception is in fact not as simple as it sounds there is a lot of chemistry

at various horizontal distances from the lamp. The light detector (photocell) will enable us to make light intensity measurements that are more precise than those made with the human eye. The photocell converts light intensity to an electrical potential difference‚ which can be measured with a voltmeter. Using our measurements made from numerous elevations above the table‚ we assumed voltmeters were proportional to the intensity of light and observed a relationship between position and light intensity
