Sciousness. Explain how injecting excess insulin can
impair brain function. Explain also why an injection of
glucagon can restore normal function.
3. Endocrine disruptors can interfere with biological pro-
cesses by mimicking hormones, activating or blocking
the body's hormone receptors, disrupting the synthesis
of hormones, or altering their breakdown. How are these
mechanisms of action similar to those of the psychoactive
drugs that act at synapses?
