Answer: 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 correct answer is C. The medial surface of the left lung exhibits a concavity called Cardiac Notch.
Explanation:
The two lungs are not of equal size because the heart is located somewhat oblique, with its apex slightly to the left of the middle plane of the body, which forces the left lung to have a concavity in its medial aspect to accommodate the apex of the heart, resulting smaller than the right lung. The cavity in the left lung that houses the apex of the heart is called the cardiac notch.
