Different body cells can respond differently to the same peptide hormone because _____.
a. the hormone is chemically modified in different ways as it travels through the circulatory system
b. different target cells have different sets of genes
c. each cell converts that hormone to a different molecule
d. a target cell's response is determined by the components of its signal transduction pathways

Respuesta :

The correct answer is d: a target cell's response is determined by the components of its signal transduction pathways.
The response of a cell to a hormone depends on the cell’s receptor and a signal transduction. When a peptide hormone binds to a receptor on the cell membrane, a second messenger is activated in the cytoplasm. The second messenger has a role of triggering signal transduction leading to the cellular response. Lots of different signal transduction processes (for example, different intracellular proteins) are used to coordinate the behaviour of target cells.
