beta receptors

• they are signaling proteins
• normally adrenaline binds to trigger “go”
• propranolol is synthetically designed to be able to bind to them too -> be similar enough to adrenaline, but not similar enough to be recognized as adrenaline, so it can just sit there and basically do nothing
• its like buying the whole row of your plane seat just so there’s nobody that’ll fck u up, the seats could be taken, but you don’t want that to happen
• it blocks (-> beta blockers) the receptor from adrenaline and thus from reacting like it would normally do when adrenaline binds (pump up heart rate, blood pressure, etc)
