Respuesta :
Steroids are fat-soluble signal molecules that are derived from cholesterol
Answer:
D) Steroids
Explanation:
Steroids are small fat soluble hydrophobic ligands found in animals, plants and fungi. They can directly cross the plasma membrane and interact with internal receptors.
They are derived from cholesterol and hence are composed of a hydrocarbon skeleton with four fused rings like cholesterol. Different steroids vary by the functional groups that are attached to them. Examples of steroid hormones are estradiol and testosterone.
