What must be present for any type of hormone to be able to act on a target cell?Multiple ChoiceProtease enzymesHormone response elementsProtein receptorsProtein channels

Fill in the Blank QuestionFill in the blank question.Protein molecules that act as receptors for nonsteroid hormones typically have a site, which interacts with the hormone. As a result, the site of the receptor interacts with other membrane proteins, triggering a cellular response.

What makes a cell a target of a particular hormone?Multiple choice question.The location of the target cell in the bodyThe chemical properties of the hormoneThe location of the gland that secretes the hormoneThe presence of a receptor for that particular hormone
