Question

Quizplus · Accepted Answer

Hydrophobic molecules cannot pass through the plasma membrane through simple diffusion, and thus require cytosolic receptors to bind to, in order to initiate signalling cascades. This is characteristic of hormonal signalling, which includes molecules such as steroids and thyroid hormones. Autocrine, paracrine, endocrine, and synaptic signalling are not exclusively characterized by hydrophobic molecules passing through the plasma membrane.
