A thermodynamically spontaneous reaction O A. happens quickly, with no addition o energy to the system happens quickly whether or not there is an addition of energy to the system OB. С. °°has the capacity to happen but might not happen quickly has the capacity to happen but only in the presence of a catalyst

Which of the following is true of thermodynamically spontaneous reactions? O A. They are all energy-yielding They are all energy-consuming They all result in an increase in the temperature of the system They all result in a decrease in the temperature of the system В.

Explain what is happening in this photo in terms of kineticenergy and potential energy. Include the energy conversionsthat occur when the penguins eat fish and climb back upon the glacier. Describe the role of ATP and enzymes in theunderlying molecular processes, including what happens tothe free energy of some of the molecules involved.

Regarding the reasoning for the Michaelis-Menten equation to be unsuitable for accurate analysis of experimental data, select all that apply: It is nonlinear It is only valid for reactions at equilibrium It is not valid under experimental conditions Extrapolation to Vm is inaccurate and therefore Km also cannot be accurately described
