Question

Quizplus · Accepted Answer

Signal molecules are generally classified based on their receptors into two main types: cell surface receptors (such as G protein-coupled receptors, ion channel receptors, and enzyme-linked receptors like protein kinases) and intracellular receptors (such as steroid hormone receptors). None of the options provided accurately reflect this classification.
