The formation of an action potential can be divided into five steps. (1) A stimulus from a sensory cell or another neuron causes the target cell to depolarize toward the threshold potential. (2) If the threshold of excitation is reached‚ all Na+ channels open and the membrane depolarizes. (3) At the peak action potential‚ K+ channels open and K+ begins to leave the cell. At the same time‚ Na+ channels close. (4) The membrane becomes hyperpolarized as K+ ions continue to leave the cell. The

Potential Energy • Definition and Mathematics of Work • Calculating the Amount of Work Done by Forces • Potential Energy • Kinetic Energy • Mechanical Energy • Power An object can store energy as the result of its position. For example‚ the heavy ball of a demolition machine is storing energy when it is held at an elevated position. This stored energy of position is referred to as potential energy. Similarly‚ a drawn bow is able to store energy as the result of its position. When assuming

successful agency-client relationship rely on understanding: 1. What are the key drivers of successful client retention? 2. Are these in line with the key success factors for new client attraction? In response to answering these questions‚ our report aims to investigate segmentation and buyer behavior within the advertising industry. The selection and retention criteria of advertising agencies can be described by three distinct elements: 1. Relationship Management: the chemistry between the client

BUYING BEHAVIORS This study will allow us to understand how local consumers make decisions to buy. Based on those facts‚ we will be able to have an effective strategy and avoid mistakes related to cultural differences. CONSUMERS PERCEPTIONS COUNTRY OF ORIGINS First‚ we will look at the perception of the country of origin. In that case‚ France ’s opinions toward the United States vary widely. Therefore‚ it is hard to say if we ought to display ostentatiously the origin of the American Product

There are 5 stages which a consumer often goes through when he/she around their Purchase. These stages also exist because of normal human psychology. These 5 stages are : Problem/Need Recognition- This is in general the first stage in which the consumer recognizes that what essentially is the problem or need and hence accordingly a consumer can identify the product or kind of product which would be required by the consumer.

A graded potential in physiology‚ is described as local changes in membrane potential that occur in varying grades or degrees of magnitude or strength. When compared to graded potential‚ an action potential is described as brief‚ rapid‚ large (100mV) changes in membrane potential during which the potential actually reverses so that the inside of the excitable cell transiently becomes more positive than the outside. As with a graded potential‚ an action potential involves only a small portion of

THE WORK DONE BY A CONSERVATIVE FORCE ALWAYS HAS FOUR PROPERTIES: 1. It can be expressed as the difference between the initial and final values of a potential-energy function. 3. It is independent of the path of the body and depends only on the starting and ending points. 2. It is reversible. 4. When the starting and ending points are the same‚ the total work is zero. The total mechanical energy ME = K + U is constant. Object moving in a uniform gravitational field gravitational a

BIOSC 048: Problem Set Questions 1. Given that cell A has significantly more nongated K+ channels than cell B‚ which cell has the larger resting membrane potential? Explain. If the permeability to K is higher in A than in B‚ then the resting membrane potential (rmp) will be closer to the equilibrium potential in cell A‚ which means the rmp will be more negative in cell A than in cell B; or in other words‚ the potential difference will be LARGER in cell A. 2. Predict the effect of a reduced
