Why is the AG of ATP hydrolysis in the cell about twice as great as the AG of ATP hydrolysis in a test tube under standard conditions? O a. A cell is an open system, whereas a test tube is a closed system. O b. Reactant and product concentrations in the test tube are different from those in the cell. O C. ATP hydrolysis in cells is catalyzed by enzymes, whereas the reaction in a test tube occurs spontaneously. O d. ATP hydrolysis in a test tube releases more heat than ATP hydrolysis associated with cellular metabolism.

Why is the AG of ATP hydrolysis in the cell about twice as great as the AG of ATP hydrolysis in a test tube under standard conditions?
O a. A cell is an open system, whereas a test tube is a closed system.
O b. Reactant and product concentrations in the test tube are difterent from those in the cell.
O C. ATP hydrolysis in cells is catalyzed by enzymes, whereas the reaction in a test tube occurs spontaneously.
O d. ATP hydrolysis in a test tube releases more heat than ATP hydrolysis associated with cellular metabolism.
