- One such laboratory study investigated the binding of a hormone to three different receptor proteins in the cell membrane. The data collected are shown in the table below: 1) Provide a brief explanation as to why ligand binding to proteins must be a reversible process. 2) Calculate the dissociation constant (Kd) for the hormone binding to each of the three proteins. 3) Which of the proteins demonstrate the tightest/strongest binding of the hormone? Which demonstrates the least tight binding of the hormone? What is the basis for your answer?Draw the structure of cholesterol and write the biosynthetic relations of steroid hormones starting from cholesterol.The hormones known as "catecholamines" (adrenaline, noradrenaline, and dopamine) are not lipid-soluble. Therefore their receptor sites are: O a) On the inside of the plasma membrane O b) On the outside of the plasma membrane O c) In the cell cytoplasm O d) In the cell nucleus
