I am wondering can intracellular metabolic compounds enter the cell from the extracellular? Which mechanisms are involved allow above compounds enter cells? Passive fusion? Cell endocytosis? Or other mechanisms？There are many types of compounds such as Phenylethylamine,3-hydroxybenzoic acid,Catechol,1,2,4-benzenetriol,Naphthalene,benzoic acid,Prenol,glycerin,Butyric acid，
Tannic acid，Myristic acid and etc. How can I find these mechanisms efficiently?
Dear Weixin,
Here is a good review article for you:

Passive diffusion from extracellular to the cell will require concentration gradient for the substance. As ur asking about metabolic compounds there should be a lower concentration of it in the cell in order to move. For endocytosis to occur specific protien domains should be there to act like a receptor for the metabolic compound in order to move them
