Signal Transduction Pathways Require Receptor.  Small Molecules Steroids

Not all signals require receptors; small molecules like steroids can enter the cell membrane and directly trigger a response.

Some signals, like steroids, bypass receptors by passing through the cell membrane to directly stimulate the cell.

Text Not all signal transduction pathways require a receptor.  For example, small molecules such as steroids can pass through target cell membrane and cause the stimulus directly.
