Quizplus · Accepted Answer

Metabotropic receptors do not form a membrane-spanning pore through which ions pass. Instead, they activate signaling pathways inside the cell through G proteins and second messengers. Ion channels, on the other hand, form pores through which ions can pass across the cell membrane.
