Cell Signalling + everything before Flashcards
what is the difference between agonists and antagonists
agonists - initiate changes in cell function, producing effects
antagonists - binds to receptors without initiating any effect
antagonists have how much efficacy
no efficacy
agonists have how much efficacy
high efficacy
agonists potency depends on what two parameters
efficacy and affinity
what are cations
positively charged ions
what are anions
negatively charged ions
in metabolic processes, what happens to the pH
it produces acidic by-products therefore reducing the pH
how do hormones from the endocrine glands get to their targets
hormones secrete out of the cell and into the bloodstream where they will travel to the the target cell and bind to receptors
what happens to hormones that binds to cells without receptors
no response
