The resting membrane potential results from A. uneven distribution of ions across the cell membrane only. B. differences in membrane permeability to Na+ and K+ only C. activity of the sodium/potassium pump only. D. uneven distribution of ions across the cell membrane, differences in membrane permeability to Na+ and K+, and sodium/potassium pump activity

Under what conditions could the opening of a chloride channel actually depolarize a neuron rather than hyperpolarize it? i. The neuron is resting at -75 mV ii. The extracellular chloride concentration is lower than the intracellular chloride concentration iii. The neuron is close to its threshold of -55 mV O a. i only O b. ii only O c. i and ii only O d. ii and iii only O e. i, ii, and i O f. None of these

What happen when you open the the GABA channels ? Does it rise the membrane permeability of Na+, K+ or CL? Choose one here? Explain short and briefly only ?

9. If sodium permeability (Pna) increases compared to normal, what is the effect on the membrane potential? (determine: change in charge on the inside of the membrane and polarity)
