The release of neurotransmitter from a neuron is an example of:
a. exocytosis and is a form of passive transport.
b. pinocytosis and it is a form of primary active transport.
c. receptor-mediated endocytosis and it requires expenditure of atp.
d. endocytosis and is a form of passive transport.
e. exocytosis and it requires expenditure of atp

E. exocytosis and it requires expenditure of ATP

Explanation:

Neurotransmitters are molecules released by synaptic pre-neurons and are the means of communication in a chemical synapse. They bind to neurotransmitter receptors and can attach to an ion channel (ionotropic receptors) or an intracellular signaling process (metabotropic receptors). Neurotransmitters are specific for the receptor they bind to and elicit a specific response in postsynaptic neurons, resulting in an excitatory or inhibitory signal. Because exocytosis is an example of active transport, it requires expenditure of ATP.

the answer to your question is (pancreas).

a less-active, mature cell in areolar connective tissue would be a:

a. fibroblast

b. fibrocyte

c. chondroblast

d. chondrocyte
