BIO 116 EXAM #4 - PART 3 WITH
QUESTIONS AND ANSWERS LATEST
UPDATE 2026\2027
chemical signals that are involved in the
regulation of the other organs in the
hormone body
communication between cells, body
parts, and individuals
secretes hormones into the bloodstream
endocrine gland hormones then affect targets cells with
specific receptors
hormones are secreted by glands
hormones are carried in the
how do hormones differ from
bloodstream
neurotransmitters?
hormones have a slow, prolonged
response to stimuli
act as “first” messengers
cannot cross the plasma membrane;
bind to receptors on the target cell
nonsteroid (peptide) hormones membrane
trigger second messengers (cAMP)
inside the cell
influence activity of the target cell
made from cholesterol
diffuse through the cell and nuclear
membrane
steroid hormones bind directly to receptors inside the
DNA
results in cell production that influences
cell activity like proteins and enzymes
, interferes with the natural hormone
why are there usually additional concerns production in the body
surrounding steroid hormones?
they act more slowly, but last longer
