Question
im having trouble completing this homework assignment. i only was able to figure a few of them out.When the nerve impulse reaches the axon terminal, __(1)__ ions enter the terminal through voltage-regulated gates. The effect of the entry of these ions is to promote fusion of synaptic vesicles with the ____(2)____. Exocytosis of __(3)___ molecules follows. These diffuse across the __(4)___ and bind to ___(5)____ on the postsynaptic membrane, causing ion channels to open. The current flows that result cause local changes in the ____(6)_____.
Channels that remain open are called ___(7)___ channels. Channels that open and close in response to various chemcal stimuli are called ___(8)____. Ions move across the membrane in response to a difference in concentration, which is called the ___(9)_____gradient, and also in response to difference in charge, which is called the ___(10)_____ gradient.
i believe i have figured out 4,5 and 8 but after that im stumped.
