Question

Which of the following accurately describes a general difference between hormones and neurotransmitters?

a. Hormones are released directly into the bloodstream, whereas neurotransmitters are not
b. Hormones can be hydrophilic, whereas neurotransmitters are generally not hydrophilic
c. Hormones can increase heart rate faster than neurotransmitters can
d. Hormones are always bigger than neurotransmitters

Answer 1

Hormones are released directly into the bloodstream and travel throughout the body, while neurotransmitters are released at synapses and have localized effects. Some hormones can be hydrophilic, but not all. The size of hormones and neurotransmitters can vary.

Step-by-step explanation:

Hormones and neurotransmitters are both signaling molecules that transmit messages in the body, but they have key differences. One difference is that hormones are released directly into the bloodstream and travel throughout the body, affecting any cells that have receptors for them. On the other hand, neurotransmitters are released at synapses and have localized effects on nearby cells.

Another difference is that while neurotransmitters are generally not hydrophilic, some hormones can be hydrophilic. Hydrophilic hormones are water-soluble and can easily travel through the bloodstream.

It is important to note that the size of hormones and neurotransmitters can vary, so it is not accurate to say that hormones are always bigger than neurotransmitters.
