A neurotransmitter may have an excitatory or an inhibitory effect on the postsynaptic cell, depending on __________.
Otrada [13]

A neurotransmitter can have an excitatory or inhibitory effect on the postsynaptic cell, depending on <u>which of its </u><u>receptor(s</u><u>) are present on the </u><u>postsynaptic</u><u> (target) cell.</u>

<h3>How do excitatory and inhibitory neurotransmitters act?</h3>

Sometimes neurotransmitters can bind to receptors and cause an electrical signal to be transmitted through the cell (excitatory). In other cases, the neurotransmitter can prevent the signal from continuing, preventing the message from being carried (inhibitory).

With this information, we can conclude that a neurotransmitter is a signaling molecule secreted by a neuron to affect another cell across a synapse.

What characteristic of viruses distinguishes them from cells?
Helga [31]

Answer: Viruses, although not living things, do show some characteristics that they are living. Because they can't reproduce by themselves (without a host), viruses are not considered living. They are made of proteins and glycoproteins like cells are. They contain genetic information needed to produce more viruses in the form of DNA or RNA.

They are acellular, that is, they contain no cytoplasm or cellular organelles. They carry out no metabolism on their own and must replicate using the host cell's metabolic machinery.

Identify how a hormone molecule performs its function. formation of mRNA in the nucleus initiation of DNA replication because of
expeople1 [14]

Answer:

binding of the hormone molecule with its receptor of the cell.

Explanation:

Hormones are chemical messengers secreted or released by endocrine glands to effect a response in another location called target location. Hormones are proteinous molecules and like every other protein, its function is determined by its shape.

Hormones function or effect their changes by binding to the receptor of the target cell. The hormone recognizes and will only bind to its own receptor molecule on its target cell on order to bring about any change. This defines the specificity of the hormone.
