Comparison of Hormones and Neurotransmitters
Both hormones and neurotransmitters are chemical messengers that must bind to specific receptors to transmit their signals. However, they differ significantly in their mechanism, scope, and timing. Hormones are secreted into the bloodstream, leading to widespread effects that are slower to manifest but tend to be longer-lasting. In contrast, neurotransmitters are released in close proximity to their target cells, resulting in localized, rapid, and transient effects.

A specific chemical messenger is released by a cell and causes an immediate, short-lived response in a single, neighboring cell. Based on the fundamental properties of hormonal signaling, how would the effects of a hormone differ from the effects of the messenger described?
A pharmaceutical company is developing a new medication intended to produce a very rapid, localized effect on a single organ. The medication is designed to function like a hormone, using the body's circulatory system for delivery. Based on the fundamental principles of how hormones work, what is the primary challenge this design faces?
