What is the role of ATP in coupling the cell's anabolic and catabolic process?

Question

give short answer if u can

Answer 1

Metabolic reactions are organized into pathways that are orderly series of enzymatically controlled reactions. Metabolic pathways are generally of two types:

1. Catabolic pathways = Metabolic pathways that release energy ( ATP) by breaking down complex molecules to simpler compounds (e.g., cellular respiration which degrades glucose to carbon dioxide and water; provides energy (ATP) for cellular work).

2. Anabolic pathways = Metabolic pathways that consume energy ( ATP) to build complicated molecules from simpler ones (e.g., photosynthesis which synthesizes glucose from CO2 and H2O; any synthesis of a macromolecule from its monomers).

Metabolic reactions may be coupled, so that energy released from a catabolic reaction can be used to drive an anabolic one.  ( HERE also there is the role of ATP observed)

Catabolic reactions or pathways produce energy as ATP, which can be utilized in  anabolic pathways.

Apart from building blocks and ATP anabolic reactions also require a good deal of reducing power ... ( READ MORE)
