Concept #1: Chemical Reactions

Concept #2: Le Chatelier's Principle

Practice: Calmodulin is a protein that “senses” intracellular Ca2+ by binding to it. If you increase the amount of Ca2+ in a cell, which of the following do you expect? (Choose all that apply.)

Practice: Estrogen is carried in the bloodstream bound to a protein called “steroid-hormone binding protein” (SHBP). The binding is reversible and follows Le Chatelier’s Principle. Liver failure causes the amount of SHBP in the blood to decrease. Which of the following do you expect to be caused by liver failure? (Choose all that apply.)
