In order for ATP to effectively deliver energy to an enzyme, the following needs to be the case: a. a. ATP hydrolysis is spatially close to the enzyme’s active site b. There must be a separate protein present whose task is ATP hydrolysis c. There must be a phosphate acceptor present d. ATP must be formed during the reaction

Expert Solution
Step 1: Endergonic reaction are driven to completion by using ATP
Endergonic reactions are reactions that cannot be driven forward without an input of energy. Endergonic reactions have a positive free energy change.
Endergonic reactions can be driven to completion by coupling them to hydrolysis of ATP.
Heterotrophic cells oxidize nutrients such as glucose to produce ATP.
