What is the charge of proteins inside a neuron? please explain why
Homework Answers
The proteins are negatively charged inside a neuron because anions which are negatively charged species are big and cannot go out through any channel.

You are studying a neuron from a newly discovered alien species, inside the neuron are many positive charged proteins, P+ Outside the neuron are high concentrations of two negatively charged ions, X- and Y-. Another ion, Z+, also exists both inside and outside the cell (assume the rules of cell membranes, permeability, electric charges and ion channels are the same as a regular neuron on Earth). 1. In its default state, the alien neuoron's membrane is permeable only to Z+....

D 4. Which of the following is TRUE regarding the resting state of a neuron? There is more K+ outside of the neuron than there is inside of the neuron. During the resting state, all of the Na+ and K+ leaky channels are nonfunctional The H+-ATPase pump is responsible for establishing the resting electrochemical gradient in the neuron. The outside of the neural cell has a positive charge while the inside of the neural cell has a negative charge.

En (mv) [] in mM 150 Inside Outside neuron neuron 10 12 120 100 1.25 250 Na+ CI Ca++ 4. Use the Goldman equation to determine the resting potential for a neuron described in the Table for question 3. Assume that at resting potential, the permeability of K+ is 8 times that of Na+, that the permeability of K+ is 3 times that of Cl., and that the permeability of Ca++ is 0.

a) What can you say about the charge density inside a piece of conducting material at electrostatic equilibrium? Justify your answer. b) Explain why two distinct equipotential surfaces cannot intersect. c) Explain why equipotential surfaces are perpendicular to the electric field lines. d) A point charge q=30nC is placed in the cavity of a conducting shell. The shell itself has a total charge of -50nC. Find the charges on the inner and outer surfaces of the shell.
