Expression of which of the following lowers the threshold for firing action potentials? O A. Voltage-dependent K* channels OB. Na+, K+-ATPase OC. GABAA receptors OD. CI channels O E. Voltage-dependent Na+ channels

What drives K+ ions through voltage gated channels while funny channels are also open? O pifference in K+ concentration across the PM O pressure potential O Both difference in K+ concentration across the PM and Membrane potential (difference in charge across the membrane) O Osmotic potential O Membrane potential (difference in charge across the membrane)

Matching (may not use all choices; may use some choices more than once) 45. Sección Release of inhibitory neurotransmitter 46. Decreased concentration of leaky sodium channels in the membrane Arsenic poisoning prevents mitochondria from making ATP 47. 48. Extreme sodium deficiency 49. Acetylcholinesterase concentration is decreased 50. Overdose of Potassium Chloride 51. Increased concentration of leaky potassium channels in the membrane Salto de columna A. Makes RMP more negative B. Makes RMP less negative
