Hormone-cell specificity hormones Though systematically ; A circulate w/ hormone specific receptors only cells are affected * target cell activation depends on 3 factors 1. Blood levels of hormone of 1 in 2. Relative number receptors on target Cell (strength) of binding between receptor and. 3 Affinity hormone · Up-Regulation : Target Cells form more receptors in response to low hormone levels more receptors formed Whormone levels * Down-Regulation : Target cells lose receptors to high hormone levels. from high levels home Ahormones target alter cell activity - The Dalter plasma membrane permeability and/or membrane potential
