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 extracellular concentration of Na+ on the magnitude of the action potential in an electrically excitable cell. If there

THREATS FACING MALAYSIA Malaysia‚ being a trading nation that highly dependent on international trade‚ our economic performance is very vulnerable to the performance of our major international trading partners. For decades‚ our economic growth has been overly reliant on external sector developments‚ foreign direct investment (FDI) and international trade. Domestic investment decisions are not base on economic fundamentals but rather these decisions are very much influenced by the market behavior

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

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

What is kinetic energy? Kinetic energy is energy due to object’s motion. Kinetic energy of an object depends on both its mass and its speed. Kinetic energy increases when mass increases. You can find kinetic energy by using the formula kinetic energy equals one half times mass times speed to the second power. What is potential energy? Some objects have stored energy as a result of their positions or shape.Potential energy is stored energy that results from the position or shape of an object.
