Within the cell, many chemical reactions that, by themselves, require energy input (have a positive free-energy change) can occur because the reactions

may be coupled to the hydrolysis of ATP

take place very slowly

take place when the cells are at unusually high temperatures

are catalyzed by enzymes

are aided by various metal ions that act as catalysts

How does a noncompetitive inhibitor decrease the rate of an enzyme reaction?

By binding at the active site of the enzymeBy changing the shape of the enzyme’s active siteBy changing the free energy change of the reactionBy acting as a coenzyme for the reactionBy decreasing the activation energy of the reaction

Which of the following statements about mitochondrial chemiosmosis is NOT true?

A proton gradient is established across the inner membrane of the mitochondrion.The potential energy released from the mitochondrial proton gradient is used to produce ATP.The mitochondrial proton gradient provides energy for muscle contraction.Proteins embedded in the inner mitochondrial membrane play an important role in ATP synthesis.Heat energy is required to establish the electron transport chain.
