what is an example of both exogenous and an endogenous ligand?
Homework Answers
Ligand is s substance which binds to a target site of a proteins and brings some conformational changes in the protein. The binding depends on the charge, structure of the ligand and the target protein etc. The binding occurs by intermolecular forces.
All hormones, neurotransmitters and drugs are ligands.
All signalling molecules in the living system are ligands. Epinephrine binding to the receptor on the cell surface is a ligand. It is endogenous ligand. Epinephrine is a hormone produced by the body.
All drugs are exogenous ligands. Asprin drug is one such ligand. Asprin also binds to receptors of the cell and bring changes in the cell functioning.

Consider the following Y_i=β_0+β_1 X_i+u_i where Xi is
endogenous. Assume that Zi is an exogenous variable that can be
used in 2SLS.
Consider the following Ý, βο + β1x, + ut where Xi is endogenous. Assume that Zi is an exogenous variable that can be used in 2 SLS. i. Define both stages of 2SLS (X and Y) Derive the 2SLS estimator for B1 Prove the estimator from (ii) is unbiased. 1. ii. iii.

For the following statements identify how you would model the change. What is the exogenous shock? How do you model it? Then identify the endogenous changes to price and quantity as the market adjusts to the shock. Due to exceptional weather there is a bountiful cocoa harvest. In the cocoa market, the exogenous shock is a(n) [decrease in demand, increase in demand, decrease in supply, OR increase in supply?] . As a result, one would expect the equilibrium price to...
