11.2 Flashcards
The flow of electrical charge
Current
Force opposing charge flow
Resistance
Do insulators have high or low resistance
High
Canalis
Pipeline
Open to reduce resistance allowing current in the form of ions to flow across the membrane
Integral membrane proteins
What are the two Main Gated ion channels
Ligand gated
Voltage gaited
Which gated ion channel is activated when bound by specific molecules like neurotransmitters and hormones
Ligated
Which gated ion channel is activated be changed in membrane potential charge
Voltage gated
Potential energy generated by charge difference
Voltage
Extracellular fluid higher in Na or K
Na
Cytoplasm higher in Na or K
K
Which Gate is action potential
Voltage
Which gate is graded or local
Ligand
What is the entire process of sending a wave or voltage charge down an axon
Action potential
Where does ap occur
Muscle cells and axon of neurons
