Question 11 (0.75 points) Which statement is INCORRECT? Steroid hormones are hydrophobic. Protein hormones are made from amino acids. Steroid hormones are made from cholesterol. Protein hormones diffuse through the target cell membrane.

The incorrect statement is: **Protein hormones diffuse through the target cell membrane.**<br /><br />Protein hormones are hydrophilic and cannot diffuse through the hydrophobic cell membrane. They bind to receptors *on* the cell membrane, triggering a signaling cascade within the cell.<br />
