Cellular Energetics

If the delta G of a reaction is negative, which response shows the best conclusion for that reaction? 

• The reaction will release more energy than was needed to form the reaction.
• Energy from the reaction can be used to do work. 
• Energy is absorbed by the reaction which then can be used to power other reactions. 
• Energy is absorbed within the reaction and distributed unevenly throughout the molecule.

The induced fit model of enzyme activity suggests which of the following?

• the binding of substrate depends on the conformation of the active site
• the binding of an activator alters the active site to enable binding of products more tightly
• binding of substrate changes the conformation of the active site to bind substrate more tightly
• binging of competitive inhibitors changes the shape of the active site to bind substrate less tightly
