Though often chemically identical, the effect of hormones is slower than the effect of neurotransmitters because hormones:
A) are delivered by the bloodstream

Question

Quizplus · Accepted Answer

Hormones are delivered by the bloodstream, which allows them to travel farther and affect a wider range of target cells than neurotransmitters, which are released locally in the synaptic cleft. However, this delivery method is slower because it takes time for hormones to circulate throughout the body and reach their target cells.
