Detailed explanation-1: -The reactions governing the breakdown of food to obtain energy are called catabolic reactions. Conversely, anabolic reactions use the energy produced by catabolic reactions to synthesize larger molecules from smaller ones, such as when the body forms proteins by stringing together amino acids.

Detailed explanation-2: -Typically, anabolic and catabolic reactions are coupled, with catabolism providing the activation energy for anabolism. The hydrolysis of adenosine triphosphate (ATP) powers many anabolic processes. In general, condensation and reduction reactions are the mechanisms behind anabolism.

Detailed explanation-3: -When an anabolic process is paired with a catabolic process, what must be true? The catabolic process must release at least as much energy as is required to drive the anabolic process.

Detailed explanation-4: -Catabolic and anabolic pathways are often coupled in the cell because the free energy released from one pathway is used to drive another. The catabolic pathway is a pathway through which energy is released by breaking down complex molecules or compounds into simpler ones.
