Exam 3: Neurotransmission

All of the following is true for glutamate except:

Why does an action potential only reach a particular value?

What effect on a neuron's resting potential would a drug that stop sodium-potassium pump activity likely have?

Neurotransmitters may also bind to receptors outside of the synapse,a process called _____________ neurotransmission

List and describe the steps occurring in neurotransmission

Calcium causes _____________,the fusing of synaptic vesicles to the axon membrane and release of stored neurotransmitters into the synaptic cleft

Large molecule neurotransmitters are typical transported into vesicles in the:

Where does the synthesis of large neurotransmitter molecules typically occur?

The number of action potentials occurring per unit of time is referred to as the:

Compare and contrast ionotropic and metabotropic receptors.

GABA is thought of as an inhibitory neurotransmitter because:

Which of the following is an example of a concentration gradient?

Why might a researcher wish to design a drug that inhibited autoreceptors for a particular neurotransmitter?

Why do action potentials only travel down the axon and not the other direction?

The activation of a neurotransmitter receptor is another way of stating that:

The binding of a neurotransmitter causes a _____________ change in the receptor to occur.

Channels that open or close depending on local potential changes are called:

An excitatory postsynaptic potential hyperpolarizes a local potential.

Depolarization means that the charge inside a cell approaches the charge outside of the cell.

A(n)_______________ is an enzyme that causes phosphorylation of a substrate protein.
