Classify each of the statements and hormone interactions with the appropriate interactive effect. One hormone enhances the target organ's response to a second hormone that is secreted later. Two or more hormones act together to produce an effect that is greater than the sum of their separate effects. The effects of estrogen and progesterone on the uterus. The effects of insulin and glucagon on blood glucose levels. The effects of FSH and testosterone on sperm production. One hormone opposes the action of another. Antagonistic. Permissive. Synergistic.
