please explain how hydrophobic and hydrophilic hormones differ in how they produce effects on their target?

Question

cells. many thanks

Answer 1

OK hydrophobic hormones pass through the plasma membrane, hydrophillic hormones don't. This means that hydrophillic hormones have to pass the message through the plasma membrane in another way e.g. adrenaline binds to a receptor on the membrane, which then activates adenylate cyclase producing cAMP which acts as a 'second messenger' activating and deactivating enzymes within the cell as necessary (if you're interested look up the beta adrenergic response.

Because hydrophobic hormones can pass through the cell membrane they can work more directly, the hormone can bind a receptor in the cytoplasm, the complex may then go onto bind DNA for example. Try looking up steroid hormones they are one example of hydrophobic hormones.

Answer 2

Hydrophobic hormones act on cell walls, membbranes and other lipids(adsorbed). Hydrophilic hormones are absorbed.

Answer 3

Hydrophilic hormones mix readily with water. Hydrophobic ones are afraid of water and will not mix.

Answer 4

hydrophilic hormones have affinity towards water while d hydrophobic do not have.........it can be related to the function of hydrophilic colloids in plants//

Answer 7

It determines whether they can cross membranes

Answer 8

It's probabaly stated there in your text book.
