Question

What role does ATP play in coupled reactions?

Answer 1

Answer: i m explaining in simple words

1. ATP is first used to store energy from a catabolic reaction and then used to release energy for an anabolic reaction.
2. Another use of ATP is phosphorylation of different substrates including proteins.

Explanation:

hey take reference of diagram also

Answer 2

Answer:

ATP produces energy for both energy-consuming endergonic processes and energy-releasing exergonic reactions that require a minimal activation energy input.

Explanation:

Coupled Reaction:

• A coupled reaction is a chemical process in which energy is transferred from one side to the other via a characteristic intermediate.  
• The formation of ATP, which is an endergonic process connected to proton gradient dissipation is an example of coupled reaction

ATP:

ATP stands  for adenosine triphosphate.

It is a tiny molecule that is usually referred to as the cell's energy currency.

Role of ATP in energy coupling

• Cells generate energy by combining the exergonic reaction of ATP hydrolysis with endergonic reactions.
• Phosphorylation is the process by which ATP transfers its phosphate group to another molecule.
• In energy coupling, ATP is the molecule whose burst of energy is used to pair an exergonic process to fuel an endergonic reaction.
• When ATP is involved in the reaction, the common intermediate is  phosphorylated molecule. It is a molecule to which one of ATP's phosphate groups has been attached.
