What determines if a cell is a target cell for a particular hormone?

Answer 1

If the signal molecule is able to fit through the cell membrane, it will bind to an intracellular receptor, if it cannot pass through the cell membrane, it will bind to an external membrane-surface receptor.

Answer 2

there are certain receptors on target cells that only accept certain hormones, like a lock and key. Hormones flow throughout your body and come into contact with many cells, but they ONLY effect the cells with the receptor for that hormone

Answer 3

The binding of a hormone to a receptor is the first step. Target cell activation by hormone-receptor interaction depends equally on 3 factors. First the blood levels of the hormone, second ,relative numbers of receptors for that hormone on or in the target cells and the third ,strength of the binding between the hormone cell and the receptors.

Answer 4

Generally, the receptor on the cell, the lock, is entered by the signaling molecule as a key enters a lock. Then a signal transduction pathway is initiated and a cascade effect ensues. Some lipid signaling molecules can diffuse into the cell right through the cell membrane.

Answer 5

Certain cells only react to certain messages. A hormone might only affect one type of cell and therefore, only that type of cell will be a target cell.

Answer 6

Hormones moves through the body. If it touches a cell that has the correct receptors, it binds to the cell and prompts the cell to make certain proteins or enzymes

Answer 7

Receptors
