Question

A water-soluble hormone approaches its target cell. Which will happen first? (2 points) The hormone's signal will be transduced through the cytoplasm of the target cell The hormone's signal will interact with the target cell's DNA The target cell will make proteins that alter the cell's function The hormone's signal will enter the nucleus

Answer 1

The hormone's signal is transduced through the cytoplasm of the target cell.

"Water-soluble hormones include glycoproteins, catecholamine's, and peptide hormones composed of polypeptides, e.g. thyroid-stimulating hormone, follicle-stimulating hormone, luteinizing hormone and insulin. These molecules are not lipid-soluble and therefore cannot diffuse through cell membranes.
