Examining a pathway inside a cell, you determine the following: A+ B --> C + D Which of the follow statements is / are true. (Select all that apply) Possible rate limiting step. Step is in equilibrium. Step does not require energy. Increasing D may decrease C. Likely point of regulation. Given the following: A+B C + D at equilibrium the measured concentrations are: A= 3 M B = 2M C = 5M D = 4 M Select the statements that is / are true. (Select all that apply) The reaction releases energy. The reaction is not at equilibrium because the concentrations vary dramatically The keq is 3.33 The reaction has a negative delta G
