Question

The phosphorylation of adp to form atp is an _____ reaction that _____ energy.

Answer 1

Endergonic...requires and input of

Answer 2

1. Endergonic

2. Input of

Step-by-step explanation:

ATP has three terminal phosphates bonded to a ribose which in turn is bonded to adenine. Loss of one terminal phosphate converts ATP into ADP and plenty of energy is released to drive other processes. On the other hand, phosphorylation of ADP into ATP is an endergonic reaction and requires a source of energy to occur. During oxidative phosphorylation, the proton motive force across the inner mitochondrial membrane drives the ADP phosphorylation.
