You are working with a mammalian cell that has K+ leak channels, Na+ leak channels, and Na+ /K+ ATPase. In the extracellular solution, you use NaCl and KCl in which both the Na+ and K+ ions were radioactively labeled. The ion concentrations are as follows: inside [K+ ] = 150 mM, inside [Na+ ] = 10 mM, outside [K+ ] = 15 mM, outside [Na+ ] = 140 mM. a. When the Na+ ions are at electrochemical equilibrium, what is...

Constants Part A The biochemistry that takes place inside cells depends on various elements, such as sodium, potassium, and calcium, that are dissolved in water as ions. These ions enter cells through narrow pores in the cell membrane known as ion channels. Each ion channel, which is formed from a specialized protein molecule, is selective for one type of ion. High-resolution measurements have shown that an ion channel is a 0.30-nm-diameter cylinder with length of 5.0 nm. The intracellular fluid...

Let’s consider an electrical current through a single ion channel, as shown in the following figure. We start by treating an ion channel as a cylindrical pore through the cell membrane. The channel is of length L ≈ 5 nm and is filled with water. The concentration difference of Na+ ions across the channel is Δc ≈ 100 mM. This concentration difference produces a flux of ions through the channel given by DΔc/L, where D is the diffusion constant for...

Special channels called aquaporins allow water to move between cells. These channel proteins are selective- they freely let water molecules through the membrane but NOT ions or other molecules- but (like leak channels) are not gated.Based on those facts, state which of the following would be the most likely to determines the direction (and how quickly) water can move across a membrane using aquaporins, and (in a few sentences) explain your answer. how much ATP is present inside the cell...
