Students have asked these similar questions
Generally, a cell that is affected by a particular steroid hormone would be expected to have ________.
enzymes that are activated or inactivated by the hormone's second messenger
a receptor inside the cell that binds the hormone
a cell-surface receptor that binds the hormone
DNA sites that interact with the hormone
“Some hormones are produced as inactive and then get converted into active hormone”
– justify this statement using an appropriate example.
Hormones are often synthesized and stored in an inactiveform within secretory vesicles. Secretion usually occurs onlywhen the hormone-producing cell is stimulated. Explain theadvantages that this process has over making the hormonemolecules as they are needed.
