question 49

• B) Cells are less efficient at heat production than nonliving systems.
• C) The hydrolysis of ATP in a cell produces different chemical products than does the reaction in a test tube.
• D) The reaction in cells must be catalyzed by enzymes, but the reaction in a test tube does not need enzymes.
• E) Reactant and product concentrations in the test tube are different from those in the cell.
