Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Phosphorylation of ADP ____
A
requires an input of energy
B
releases energy
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The energy released when electrons are passed from higher-energy NADH or FADH2 to the lower-energy O2 is required to phosphorylate ADP and once again generate ATP. It is this energy coupling and phosphorylation of ADP to ATP that gives the electron transport chain the name oxidative phosphorylation.

Detailed explanation-2: -ADP is adenosine diphosphate . Therefore, energy is required for the formation of these bonds attaching phosphate group.

Detailed explanation-3: -group to a molecule of adenosine diphosphate (ADP)-or to state it in chemical terms, by the phosphorylation of ADP. This reaction requires a substantial input of energy, much of which is captured in the bond that links the added phosphate group to ADP.

Detailed explanation-4: -ADP can be “recharged” to form ATP by the addition of energy, combining with Pi in a process that releases a molecule of water.

Detailed explanation-5: -The synthesis of high-energy-transfer compounds, such as ATP, involves phosphorylation. ATP is formed by phosphorylation of ADP, with energy for the phosphorylation being provided by an exergonic reaction.
